5.0 CHAIR’S REMARKS & REPORT – STEPHEN ANTOSZ
The Chair’s Report was presented at the Monday General Session.
5.1 IEEE PES TECHNICAL COUNCIL
The Technical Council of the IEEE Power Energy Society (PES) is presently composed of the Chairpersons
of the PES Technical Committees, plus the Chairpersons of Standing Committees reporting to it. For
operating functions it is responsible to the IEEE Technical Advisory Board and for technical activities to the
IEEE Technical Activities Board.
The PES Technical Committees report to the Technical Council on matters concerning membership,
technical publications, recognition, scope and the coordination of the Power Energy Society generated
standards. For standards relating to their technical scope, the Technical Committees work directly with the
IEEE Standards Board and the Power Energy Society Standards Coordinating Committee.
For further details on the Statement of Purpose and Scope of Activities for the PES Technical Council Please
see; http://www.ieee-pes.org/statement-of-purpose-and-scope-of-activities-for-the-pes-technical-council.

5.2 TRANSFORMERS COMMITTEE ACTIVITIES
5.2.1 New Subcommittee Chairs. Appointments by Committee Chair.
5.2.2 Dielectric Test SC -- Ajith Varghese replaced Michael Franchek, after the Spring 2016 meeting.
5.2.2.1 Power Transformers SC -- Bill Griesacker will replace Joe Watson, after Vancouver Fall 2016
meeting.
5.2.2.2 Insulation Life SC -- Sheldon Kennedy replaced Bruce Forsyth on Jan 1, 2016.
5.2.3 Liaison Representatives. Appointed by Committee Chair.
• CIGRE - Raj Ahuja
• IEC TC-14 Technical Advisor to USNC - Phil Hopkinson
• Standards Coordinating Committee, SCC No. 18 (NFPA/NEC) – David Brender replaces Ned Brush
• Standards Coordinating Committee, SCC No. 4 (Electrical Insulation) - Paulette Payne Powell
5.2.4 New CD with compilation of C57 documents
Instead of the printed edition, IEEE put out a CD in 2002, 2008, and 2011. Now we have done another one
this year in 2016, since the new main Standards C57.12.00 and C57.12.90 were published in March 2016.
Peter Balma is leading this effort again. The CD is ready and was for sale as part of the registration process
at the Fall meeting in Vancouver. 57 are already sold, which exceeds expectations.
5.2.5 IEEE Membership Status Elevation
5.2.5.1 All membership issues will be covered in detail by our Committee Secretary Bruce Forsyth, but I just
want to take a moment to have everyone stop and think a few moments about your membership level and
encourage you to step it up to the next level.
If you are a regular Member, then consider becoming a Senior Member. See Bruce for how to do this.
If you are an Interested Individual, then step up and get involved in some activity and become an Active
Participant. If you are an Active Participant, then apply to be a Committee Member. Observers are
welcome, but after a few meetings more active participation is encouraged.
There are over 570 people here today; many are IEEE Members and many are not. I want to encourage
everyone to become an IEEE Member, and to renew that membership every year. Furthermore, many of us
are PES and IEEE-SA Members as well. These membership categories are necessary to do much of the work
of developing IEEE Standards, so please consider adding the PES and IEEE-SA memberships to your
profile.
5.2.5.2 Emeritus Members (EM)
The Administrative Subcommittee has formed a Task Force to investigate the requirements of emeritus
membership, create a list of past and existing EM’s, review the policies and procedures regarding EM’s, and
to make suggestions for future direction regarding EM’s.
5.2.6 RFID
This issue will be covered by our Meeting Planner, Greg Anderson. We are using RFID tags on the name
badges for this Vancouver meeting in a similar manner as the last meeting. Bear with us as we implement
this new technology, which is intended to make our meetings better.
Page 22 of 56
5.2.7 Thursday morning Tutorials
We always continue to look for new and exciting topics. Tom Prevost is the leader of this activity for
coordination efforts. If interested, see Tom or any of the officers. Any feedback by attendees is welcome.
5.2.8 Association Management System
All WG’s should be using AMS to track their membership and meeting attendance. If unable to so, then
please assign it to someone who can do it.
5.2.9 Website Password Usage
It is not for public dissemination. It is for use by our meeting attendees (CM, AP, II) and associated work of
the Transformers Committee. One can think of it as a benefit of attendance and participation. Use it for
yourself and within your immediate workplace, but not beyond that.
5.2.10 100 year celebration in 2018
Based on research of AIEE and IEEE, the first recorded meeting of a transformers committee was in 1918,
making 2018 the 100 year anniversary of our committee. We will use the Spring 2018 meeting in Pittsburgh
to celebrate the occasion. We intend to have a formal banquet on Sunday with special guests and speakers, a
reunion of former members, significant honors and awards, a sumptuous reception, etc. More info to come
in the future.
5.2.11 Call for Patents (Essential Patent Claims)
We have long had the requirement imposed upon us by IEEE-SA to have a call for patents at every WG
meeting. We used to show a slide presentation at every WG meeting, but since we have 6 to 8 WG meetings
in every time slot, six times a day on Mondays and Tuesdays, this became burdensome and took up a lot of
unnecessary time. So, several years ago we implemented an alternate approach whereby we asked the patent
questions at registration. At that time, this was an approved approach. In recent days, it has been questioned
whether or not this actually meets the requirement, and we are again being asked to have a call for patents in
EVERY WG meeting. So, until we sort this out, we will ask all WG Chairs in every meeting here in
Vancouver to present the following “call for patents” in every WG meeting. Please add this “Call for
Patents” to your Agenda:
“If any individual believes that Patent Claims might be Essential Patent Claims, that fact
should be made known to the entire working group and duly recorded in the minutes of
the working group meeting.”
The Chair is required to ask any patent holder or patent applicant of a patent claim that might be or become
an Essential Patent Claim to complete and submit a Letter of Assurance.
That’s it. Don’t spend a lot of WG time on this issue. Proceed with the meeting. Record it in the minutes
and report it up the chain of command to the Subcommittee Chair (and Don Platts) for the next action, if any.
If attendees need more details about what is an essential patent claim, they should refer to our website where
there is a link for more information.

7.1.3 Association Management System (AMS) Database
The Transformers Committee AMS database of people currently has three general categories of participation
in our activities. These are: Interested Individual, Active Participant, and Committee Member. In
addition, the Committee Secretary maintains a list of Past Committee Members. Anyone can join the AMS
123 system as the system is designed for self-registration. A new participant will automatically be assigned
the role of Interested Individual when they first sign up. Based on the level of participation, the committee
administrative staff will upgrade the participation status to “Active Participant” when appropriate. The
Committee Member status however, can only be attained through a formal application with the sponsorship
of a minimum of three WG or SC chairmanships. Details of the application requirements and approval
process by the Administrative Subcommittee are outlined in our O&P manual.
The following table contains a count of the participants grouped by the four general categories (CM totals do
not include those requesting membership at this meeting).

7.2 COMMITTEE, SUBCOMMITTEES, AND WORKING GROUP ROSTERS
In order to provide indemnification to working group and subcommittee members it is crucial that
membership lists be maintained. The AM system has these functions built-in to ease these administration
tasks. It is important that each subcommittee and working group chair keep the rosters updated so that this
information can be provided to the IEEE SA.
A similar main committee roster has also been developed to track attendance for the Main Committee
General Session meeting on Monday & Thursday. The data will be used to update participant’s membership
profile.
7.3 IEEE/PES AND IEEE/SA MEMBERSHIP REQUIREMENTS
As a reminder, all members of the Transformers Committee must also be members in good standing of the
Power & Energy Society (IEEE/PES) and the Standards Association (IEEE/SA).
WG Chairs must be members in good standing of the sponsoring subcommittee SC as well as the Power &
Energy Society (IEEE/PES) and the Standards Association (IEEE/SA).
7.4 COMMITTEE MEMBERSHIP MAINTENANCE
Since the spring 2016 meeting one member, Ned Brush, passed away and was removed from the membership
list. The membership list will be reviewed after the upcoming meeting and notices will be sent to members
who appear to be inactive (based on attendance) to inquire about their intentions of attending/participating in
the Committee.
7.5 ESSENTIAL PATENT CLAIMS
The Transformers Committee asks each participant at the time of meeting registration if they are aware of an
essential patent claim, and if so to provide details. An Essential Patent Claim is any Patent Claim the use of
which was necessary to create a compliant implementation of the IEEE Standard when there was no
commercially and technically feasible non-infringing alternative. In other words, if an IEEE Standard
REQUIRES the use of a product or process that is already patented, then this could be an essential patent
claim. If they did, they would be instructed to have the patent holder’s legal team file a Letter of Assurance
(LOA) with the IEEE-SA Standards Board Patent Committee. There is a link to this information on the
transformerscommittee.org website under Patent Disclosure Requirements.
For the Fall 2016 meeting in Vancouver, most people answered “NO” to the Patent question. There were 10
people who answered “YES” that they were aware of an essential patent claim. Of these 7 provided no
details and were therefore not considered any further. The remaining 3 were reviewed:
1. One registrant prefers to raise any EPC issues per the IEEE-SASB Operations Manual Clause 6.3.2
Call for Patents.
2. PC57.147 (Insulating Fluids SC) – There was a negative vote on the revision of PC57.147 in which
the voter's comment stated the document may contain one or more potential standard essential
patents for which no letter of assurance has been filed.
3. PC57.147 (Insulating Fluids SC) – A registrant referenced a patent and asked if there is some sort of
agreement between IEEE and the patent holder in lieu of an LOA, and inquired as to the details of
such an agreement.
Page 28 of 56
7.6 AFFILIATION
According to the IEEE Standards Board Bylaws, there is a requirement that participants of an IEEE meeting
disclose their employer and affiliation. Consultants must state if they are sponsored or not. It is not
sufficient to simply announce "My name is John Smith, and I'm a consultant." If a consultant is sponsored
by a client, it must be disclosed. If the consultant does not have a sponsor, the proper introduction is
something such as “My name is John Smith, I am a consultant, and I represent myself at this meeting.”
7.7 MEETING MINUTES
The minutes of the Spring 2016 meeting in Atlanta were posted to the committee website in September of
2016.
Subcommittee Chairs are asked to submit their respective subcommittee meeting minutes for the Vancouver
meeting to the Committee Secretary no later than Dec. 4, 2016. It is strongly recommended that meeting
minutes be prepared soon after the meeting while the activities are still fresh in member’s minds. This helps
ensure the minutes accurately reflect the activities and decisions made during the meeting.
Subcommittee meeting minutes should be submitted via e-mail to the Committee Secretary, Bruce Forsyth
[[email protected]], who will forward then on for posting on the Committee website.
The submittal file should be saved as a Word document formatted similar to this document. Attendance,
indication of quorum, names of members making any motion, seconding any motion, and the result of any
votes (affirmative and negative count) for each SC, WG, and TF meeting shall be included in all minutes.
Respectfully submitted,

8.0 TREASURER’S REPORT – GREGORY ANDERSON
Greg reported that the finances of the Committee are in good condition. As of 31st of August 2016 (end of
this reporting period), the balance was $60,111,54.
FYI: August 31st is essentially a "snap-shot" in time after all income & expenses are resolved from the
previous Spring 2016 Atlanta Meeting, and before we start spending significant funds for the Fall 2016
Vancouver Meeting.
No significant assets (PC projectors, etc.) were purchased during this reporting period.
See attached summary of the balance of this reporting period, and the previous periods.

9.0 RECOGNITION AND AWARDS REPORT – DON PLATTS
9.1 SPECIAL TRIBUTES
During the past several months since our previous meeting in March 2016 in Atlanta, GA, the Transformers
Committee and the industry lost another of our long time contributors. At our Awards luncheon on Tuesday,
the meeting attendees gathered to pay special tribute to another of our friends and collogues who passed
away in May.
Edwin “Ned” Brush II (1941 – 2016)
Edwin “Ned” Franklyn Brush Jr., 74, of New Harbor, passed away on the afternoon of May 31 at his home
after a long and courageous battle with cancer, with his loving family by his side.. Born July 17, 1941 in
Cleveland, Ohio, he was the son of Ruth and Edwin F. Brush.
Ned attended local schools in Cleveland Heights, OH and went on to receive four degrees at M.I.T.,
including a Doctorate of Science in 1967 in Materials Science and Engineering. He was fascinated by how
metallurgical processes worked and how they could be improved. His business career focused on
consulting and he worked closely with both the copper development industry and electrical transformer
industry. Ned enjoyed traveling both for work and for leisure.
He was very active and involved with M.I.T., his fraternity, and the many life-long friends he made while
attending school there. He lived a full and productive life and was loved and respected by all who were
privileged to know him.
Ned is survived by his wife of 29 years, Deborah Whitaker of Boston, Mass.; a sister; son; daughter; step-
daughter and step-son; and grandchildren.

9.4 OUTSTANDING CONTRIBUTOR AWARDS & CERTIFICATE OF APPRECIATION
In any successful organization, there are always a handful of hard working individuals, laboring behind the
scene that put in the sweat equity year after year to provide great contributions to the success of the group.
Often these contributors are not necessarily those who held the official titles. Similarly, in the Transformers
Committee, we also have a long list of these outstanding contributors. At our recent meetings, the Awards
subcommittee has started the process of recognizing the individuals who provided long tenured contributions
to our organization. As we look across the many contributors we have in the organization, we realize that
there are many deserving candidates. We hope to continue to recognize these awardees at each of our future
meeting.
The criteria for the evaluation of the nominees are primarily based on the long tenure of significant
contributions in either technical subject matter expertise and/or broader organizational impacts in our ability
to reinvent our thinking and continue our industry leadership and relevancy.
At the Awards Luncheon on Tuesday, the Transformers Committee presented a special certificate of
appreciation to Mr. Pierre Riffon for his many years of service to the Transformers Committee and also to
the industry. He has been a steadfast technical contributor over the past several decades and has brought us a
level of expertise in the dielectric test arena. As a result, the committee has benefited greatly from this
experience, wisdom, and practical expertise on testing and measurements. A brief description of his career
highlights and contributions is included below.
Mr. Riffon received his B.Sc.A. in electrical engineering from École Polytechnique de Montréal in 1980
after which he joined Hydro-Québec's Research Institute (IREQ) as a Test Engineer for the High Power
Laboratory. From 1988 to 2013, he was working as a Test Specialist for the Hydro-Québec's Quality
Control Department and was responsible for type tests on high voltage substation equipment and special
project apparatus (static and series compensation, HVDC Converter, etc...). He retired from Hydro-
Québec in 2013 and is now working as an independent consultant on high voltage equipment testing.
Pierre is a member of the IEEE Transformers Committee where he participates in several Subcommittees
and Working Groups. In particular, he is Chairman of IEEE Working Group on Test Requirements for
Instrument Transformers for Nominal Voltage 115 kV and above, and is also the Chairman of the WG on
Revision to Impulse Tests C57.12.90.
He is also the Chairman of the Canadian IEC Technical Committee TC17 and Subcommittees SC17A and
SC17C, Switchgear and control gear. Mr. Riffon is also the convener of a WG on High-Voltage
alternating current by-pass switches and the Canadian representative on SC17A/MT36 for the revision of
IEC 62271-100 High Voltage Circuit Breakers.

Pierre is a member of IEEE Power Engineering Society and registered as a Professional Engineer in the
Province of Québec.
9.5 IEEE SA STANDARDS BOARD AWARDS
In addition to the Committee Awards above, the IEEE SA SB presents its own Award to the WG Chair upon
publication of a new or revised document, and offers the WG Chair the opportunity to nominate significant
contributors to the project for an IEEE SA SB Certificate of Appreciation.
IEEE SA Award Recipients:
We have had a number of working groups that have completed their projects, their standards documents have
been published, but IEEE SA has failed to recognize them by awarding the SA plaques and Certificates of
Appreciation. At our spring meeting in Atlanta, the 9 Working Groups were again recognized as a group, at
our Tuesday luncheon, with the understanding that they may still request that the official plaque award
ceremony be at a future Transformers Committee meeting.
Several of these Working Groups will finally be recognized in Vancouver with the presentation of their SA
Award plaques. In addition, there are a few other projects that were completed in 2015, and we also have
the opportunity to recognize these Working Groups for their accomplishments.

10.10 IEEE STAFF UPDATE – ERIN SPIEWAK
Erin Spiewak introduced Malia Zaman who will be taking over Erin’s current responsibilities as program
manager for the Transformers Committee.
The current patent policy followed by the Transformers Committee does not strictly adhere to IEEE-SA
Standards Board Operations Manual requirements. The patent policy will be discussed during the Monday
luncheon. Moving forward, the patent question will continue to be asked at registration, but the patent
question (IEEE-SA SB 6.3.2) must be asked at each Working Group meeting with the results documented in
the minutes. This process is necessary since some meeting attendees may not see the patent question (e.g.
people who do not register online). A discussion related to past practice and current requirements took place.
Further discussion took place regarding what is required versus what is recommended with respect to the
patent slide presentation. Attention was made to IEEE-SA SB 6.3.2. which states:
“6.3.2 Call for patents
The chair or the chair's delegate of an IEEE standards-developing working group or the chair of an
IEEE standards Sponsor shall be responsible for informing the participants at a meeting that if any
individual believes that Patent Claims might be Essential Patent Claims, that fact should be made
Page 40 of 56
known to the entire working group and duly recorded in the minutes of the working group meeting.
This request shall occur at every standards-developing meeting once the PAR is approved by the
IEEE-SA Standards Board.
“The chair or the chair's delegate shall ask any patent holder or patent applicant of a Patent Claim
that might be or become an Essential Patent Claim to complete and submit a Letter of Assurance in
accordance with Clause 6 of the IEEE-SA Standards Board Bylaws. Information about the draft
standard will be made available upon request.”
It was noted that showing the patent slides that have been shown in the past does not comply with the
requirements stated in 6.3.2. Working Groups must make the verbal call and record the results in the WG
meeting minutes. Note that the WG Chair is not responsible for resolving any patent issues, only to ensure
potential patent claims are documented and requesting a Letter of Assurance from patent holders. Stephen
Antosz stated that he, Bruce Forsyth, Gary Hoffman, Erin Spiewak, and Don Platts will put together and
instruction for WG Chairs to provide them with the correct question to ask and instructions regarding actions
based upon response. Since this won’t be completed for this meeting, the issue will be discussed in the main
Committee tomorrow and WG Chairs will be asked to make a good faith effort to ask the question and record
the results. Gary Hoffman will provide a set of PowerPoint slides for that purpose.
IEEE has withdrawn its seat on the US National Committee (USNC) in an effort to be viewed as more
global. This does not affect its current dual logo agreement with IEC. As a result, IEEE cannot adopt IEC
documents and a process to include IEC content in our documents will have to be developed. A question
was raised regarding getting access to IEC information for use in our standards. Erin noted we would go
through ANSI since we are still accredited by ANSI.
10.11 MEETING PLANNING REPORT – GREGORY ANDERSON
No written report provided.
Highlights:
• Preliminary registration shows about 570 registrants, with about 126 companions
• The Spring 2017 meeting will be held in New Orleans, Louisiana, on April 2-6, 2017. The meeting
will be hosted by Marnie Roussell (Entergy).
• The Fall 2017 meeting location has not been determined, but the date will likely be October 29 –
November 2, 2017.
• The Spring 2018 meeting will be held in Pittsburgh, PA on March 25-29, 2018.
10.12 OLD BUSINESS
10.12.1 Status of TC O&P Manual and WG P&P Manual – Stephen Antosz & Peter Balma
Stephen Antosz noted that the Committee will be voting on proposed changes to the Transformers
Committee Organization and Procedures (O&P) Manual and the WG Policies and Procedures (P&P) Manual
during Monday’s meeting.
Peter Balma gave an overview of the proposed WG P&P Manual. First item for discussion is related to the
timing required for minutes to be completed. After some discussion, Steve Schull moved that the WG
meeting minutes be submitted within 15 days (seconded by Dan Mulkey). Stephen Antosz noted this is what
is currently in the WG P&P proposal up for vote. The motion was unanimously approved.
Page 41 of 56
Peter reviewed a few other changes and clarifications in the WG P&P proposal. Regarding quorum, the
question of whether quorum should be 50% or not less than 50% of the membership took place, but no
decision or action was taken.
Peter went on to discuss the proposed TC O&P Manual. Some of the more significant changes were
presented. Some concerns raised by Gary Hoffman based upon the direction the IEEE-SA is currently
moving. AudCom may have has some concerns that certain items related to standards development in the
TC O&P manual may need to be moved into the sponsor P&P. Gary mentioned that after reviewing the TC
O&P in more detail he believes the document really defines roles within the TC and not standards
development, and as such does not oppose the document as written.
A discussion related to who initiates reappointments of SC Chairs, Vice Chairs, Secretaries, etc. Stephen
Antosz noted the RC Chair appoints and reappoints SC Chairs.
A change for the scope of the Insulation Life Subcommittee was discussed. The proposal is to change “safe”
to “recommended” and this will be discussed during the main Committee meeting on Monday.
10.12.2 IEEE Fellow Representative – Stephen Antosz & Peter Balma
Someone from the TC needs to serve on the PES committee that evaluates people associated with
transformers. Bob Degeneff served during a recent review process. Sheldon Kennedy has agreed to serve
for the coming year.
10.12.3 New C57 Compilation CD – Erin Spiewak & Greg Anderson
The CD compilation was published and copies have been mailed those who made advanced purchases during
registration.
10.13 NEW BUSINESS
10.13.1 Emeritus Membership – Stephen Antosz & Peter Balma
Our adherence to rules related to emeritus membership has not been great. We need to follow the rules in the
sponsor P&P or recommend revisions that should be made. Stephen Antosz announced he has formed a
Task Force to review and resolve. Bruce Forsyth will chair the TF, and the members shall be Don Platts,
Stephen Antosz, Sheldon Kennedy, Steve Shull.
10.13.2 100 Year Anniversary of Transformers Committee – Stephen Antosz & Peter Balma
Peter’s research found the first reference to a Transformers Committee in 1918, making 2018 the 100 year
anniversary. A proposal has been made to make the spring 2018 a special celebration with special speakers
and events. Greg Anderson has assembled a small group to plan the meeting.
10.13.3 IEEE/IEC Issue Regarding Dual References – Paul Jarmin
Paul Jarmin discussed a problem related to dual logo documents with specific reference to the phase shifting
transformer standard. The IEC Standardization Management Board (SMB) raised a question regarding
listing normative references for both IEEE and IEC even though there is language in the document stating
that one or the other (IEEE or IEC) standard must be selected but not both. TC14 members met recently and
have informed SMB they are satisfied with the document the way it is, but this introduces the possibility that
SMB could reject the document. If that occurs the likely resolution will be to split the document into two –
one for IEEE and one for IEC.

However, there were changes to other articles that may be of interest to utilities and affect certain operations
of those utilities. Briefly, they were:
Art 210.17 requirements for electric vehicles relocated to 625.40 which has been revised. A new section
was added entitled “Wireless Power Transfer Equipment”
Art. 210.18(B) expanded
Branch circuit for electric vehicles has been relocated to Art. 210.17. For 150V or less circuits, GFCI at
“other than dwelling units” expanded from 20 A to 50 A
Art. 230.24(B)(5) New requirement for 24.5 ft. clearance for overhead service conductors over railroad
tracks.
Art. 240.67 A new article has been added to require arc-energy reduction for fuses rated 1200 amps or
larger. In 2014 code, circuit breakers rated 1200 amps or greater were covered by 240.67. Now, fuses have
been added.
Table 310.15(B)(3)(c) was removed. This was the temperature adjustment table for wire and cable on
rooftops in sunlight. The only adjustment needed now is wire and cable mounted below 7/8 inch above a
rooftop. In my opinion, this change was political, not scientific.
Table 310.15(B)(7) revised to allow and recognize 208/120 services. Had been 240/120 only.
New Art. 691 Large Scale PV Arrays
New Art. 691 covers PV overs 50 kW and larger and not under exclusive utility control
Result of NFPA Large Scale PV Task Group.
New Part IV added to Art 705 added, recognizing Microgrid Systems
Sometimes called “separately islanded systems” or “stand-alone systems”.
New Art. 706 Energy Storage Systems added
2014 NO SEPARATE ARTICLE EXISTED.
Applies to all permanently installed energy storage systems
12 other Standards are referenced
Art 708.10 (A)( 2)
Indicator lights required on CRITICAL outlets where power stays on
New Art 710 for “Stand Alone Systems” was added
New Art 712 was added covering DC Microgrids
Page 52 of 56
Includes AC systems powered by DC – AC inverters
There is some confusion over whether “microgrid” refers to utility wiring and premises. It is not
meant to.
There are a number of opportunities to represent IEEE at numerous NEC Panels.

was made by Mr. Sanjib Som and seconded by Dr. Shibao Zhang to vote on seeking a revision to the
PAR to include DC bushings. A vote was taken and 25 of 46 members voted to precede with the
revision with no objection, therefore the motion carried. See complete WG minutes in Appendix F of
this report.
A.4 Unfinished Business
A.4.1 No unfinished business to discuss at this time
A.5 New Business
A.5.1 Mr. Jim Zhang had submitted an inquiry to the SC in regards to 500kV bushings.
Although Mr. Zhang was unable to attend this meeting or thus provide additional feedback, his inquiry
was presented for discussion as it was submitted:
“Current IEEE standard has only one voltage level for 500 kV systems, which is 500 kV nominal, 550 kV max. As we also know, some of the utilities operate 500 kV system at 525 kV Nominal, therefore 550 kV max. voltage is too low for this nominal voltage. Suggested is if additional voltage level of 525 kV (nom.) will be introduced into the standard.”
Most of the comments from the SC stated that they could not offer any pertinent feedback at this time.
However, they felt if Mr. Zhang can provide some additional information at the next meeting they may be
able to share a more substantial opinion on the subject.
Annex A
Page 3 of 15
Mr. Fred Elliott, former Chair of this SC, did offer a plausible explanation. Mr. Elliott stated there is some
confusion on the 500kV nominal with a 550kV maximum. For all the bushing ratings there is only a +5%
allowance for the maximum. However, it was decided that 500kV nominal and 525kV nominal are close
enough together it could cover both by extending the maximum over 500kV up to +10% i.e. 550kV
maximum. As such, 525kV nominal with its +5% maximum is included within this range.
A.5.2 Mr. Gustavo Leal stated there is a need to have On-Line Bushing Monitoring covered in one of the
standards or guides.
Mr. Leal Stated that his company has been doing pilot testing with On-Line Bushing Monitoring and ran
into an issue when a bushing manufacturer recommending not using online bushing monitoring on their
product due to a bushing design issue. Because of this recommendation, executive management at the
utility put a hold on the bushing monitoring project. The lack of any IEEE TX standard in this area
prevented him from being able to provide suitable information to keep the bushing monitoring project
active.
A.5.3 Mr. Ajith Varghese asked that draw lead cable sizes be added to the bushing standards.
It was noted that many, if not all bushing manufacturers can provide their recommendations for the cable
sizes for their specific products.
Mr. Fred Elliott stated that it was attempted to have these values provided in the standard as Mr.
Varghese suggested. However, they could not reach a consensus amongst the bushing manufacturers,
as such it was decided that each manufacturer should provide recommendations upon request.
A.5.4 Mr. Raj Ahuja proposed that Dry Switching Impulse test be required for all bushing design tests and the
values stated on the sales drawings.
A.5.5 Several commenters raised concerns and express the need for easier determination of bushing overload.
The initial commenters stated they would like to have bushings derated so that they have a “built” in
overload capability and therefore do not have to calculate it for each application. Another commenter said
there are parameters for in-service transformers stated in the transformer standards that could be used to
determine the overload capability.
Mr. Dave Geibel stated that bushing manufacturers provide the thermal constants for their bushing so that
their capabilities can be calculated for any applications. Mr. Geibel also stated that the bushing standards
do not require any overload capabilities beyond the rated current as specified on the bushing name plate.
Some OIP bushing may have some extra capabilities but is dangerous to assume resin type bushings
have any at all. At the rated current these types of bushings may be at or very close to the Tg rating of the
material and it is dangerous to cross that threshold. Mr. Geibel stated he would like to see something
added in the bushing or transformer standards similar to IECs 120% rule-of-thumb.
Dr. Shibao Zhang commented that the first step should be to calculate the overload capability for the
specific application as the rule-of-thumb is not always sufficient and it should only be used as the last
option if you cannot obtain the needed values for calculation. Mr. Geibel also agreed that calculation is
the best/first method that should be used.
The Chair noted that Mr. Tommy Spitzer, Chair for C57.19.100, has stated he will be working on getting a
consensus for overload recommendations and add it back into the Bushing Application Guide and that he
will start work on the next revision soon.
*Note: following the meeting Mr. Fred Elliott commented to the Chair and Secretary that their SOP for
overload was to use 130% bushing rating over that of the transformer. But they had some cases that this
still wasn’t enough and found they needed 150%.

Monday, October 24, 2016 – (3:15 -4:30PM) The meeting was called to order by the WG chair Ali Naderian at 3:15 PM. This is the 7th Working group meeting. There were a total of 97 attendees; 24 members and 73 guests and 8 requested to become members. 6 memberships were granted. 1. With 24 members attending the meeting we had a quorum (out of 37 members) 2. The minutes of meeting from the WG Spring 2016 meeting in Atlanta, GA, was approved- motion for
approval from Mark Perkins and Diego Robalino. 3. Ali presented the timeline of this working guide- The WG was established in 2013. 7 TF was created
and a first draft of document was produced in 2014. It modified by working group and task force members to create D1.3. This draft document was circulated for review in 2015 and about 125 comments was received. Over several conference calls and meeting in accordance to the fall or spring meeting the comments were addressed and a second revision of the document was produced. The review of the document generated comments from 2 reviewers (thanks reviewers) which was addressed in 2 conference calls between the Atlanta meeting and Vancouver meeting. The latest draft D2.0 was created October 3rd 2016 and uploaded to the website. D2.0 draft was also sent to the Dielectric Test Subcommittee Oct 10th 2016 for review.
4. The Par is expiring on 31st of December 2017. 5. The document is ready for Ballot voting. 2/3 of the members need to approve to take the document to
ballot a) Mark Perkins questioned if the document has been reviewed by the subcommittee? b) Chuck Sweetser commented that some review of editorial nature was needed c) Don Plats indicated that the graphs may not be according to the IEEE standard practice d) If we go for review mode- volunteers are needed to review the document that has not
been produced by them e) Mario indicated that this is what happens in the ballot process –many many fresh eyes
will review the document and come with comments f) Dan Sauer indicated that if we don’t move to ballot we will probably need to have a par
extension- this can however be decided in the spring meeting and if we have come far we may also go for ballot then.
g) Ballot are fresh eyes looking at the document h) Mario Motioned to send the document for ballot- second motion came from Tom Prevost i) If we pass the voting to send the document for ballot- a second approval process needs to
be done in the Subcommittee level. j) Dan Sauer and Mark Perkins had a motion to amend the existing motion- to do send the
document to the subcommittee for review and go for ballot next meeting. k) Ajit indicated we should go for clearing out the first motion made by Tom and Mario l) The outcome from the subcommittee level could very well be go for a review and not
ballot. m) The document was voted for ballot – 16 members voted to go for ballot and 3 opposed-
thus 2/3 majority was received. The document will be recommended to the subcommittee to go for ballot
6. Peter Werelius presented a study about DFR measurements on HV-bushings. Very interesting results was presented.
7. This DFR guide produced in this WG does not include DFR on Bushings, this could be a future TF.

This survey was sent on March 27, 2016 to the TF and Dielectric Tests Subcommittee rosters. Out of 645 individuals who were asked to participate, 87 provided a reply (return rate of 13.5%). Out of these 87, 67 were approved or approved with comments (89.3% approval rate), 8 disapproved and 12 abstained. The negatives have been discussed and in order to satisfy most of them, a TF Chair counterproposal has been discussed and agreed upon. This counterproposal will be surveyed to the TF and Dielectric Tests Subcommittee rosters prior to next meeting. The motion for making new survey has been made by Mr. A. Varghese and was seconded by Mr. M. Perkins. The third item of business was related to the 2nd survey on the instantaneous voltage level at instant of chopping. This survey was sent on March 27, 2016 to the TF membership. Out of 303 individuals who were asked to participate, 48 provided a reply (return rate of 15.8%). Out of these 50, 28 were approved or approved with comments (68.2% approval rate), 13 disapproved and 7 abstained. The negatives have been discussed. In addition to the Chair proposal, a question of principle related to the need of having such additional criteria was also surveyed. 48.8 % replied "yes" and 34.8% did answer that this is not needed. Since there is no clear and large consensus, this subject will be dropped from the TF agenda unless a member will come with something which may make a better consensus. On the new business, the Chair received an Email from Phil Hopkinson regarding the need of revising impulse testing procedures and adding new transient tests in order to improve transient test severities for

covering resonance related failures during service. The TF Chair considers that this is too early for discussion and needs to be, first, fully discussed and agreed within the C57.142 TF and Dielectric Tests SubCommittee. The meeting adjourned at 5:40 pm on October 25, 2016. The adjournment motion was made by Mr. J. McBride and was seconded by Mr. A. Bolliger. The next meeting is planned to be held in New Orleans, LA, on April 4, 2017. Pierre Riffon P. Eng. TF Chair October 25, 2016.

B.3.5 TF on Revision of Low Frequency Tests Bill Griesacker, Chairman; Daniel Blaydon, Vice Chairman; Myron Bell, Secretary
Vancouver, BC – October 25, 2016, 1:45 p.m..
1. There were 129 attendees, 31 members and 98 guests present at the meeting; 10 guests requested membership, 5 of those will be granted. More than 50 % of the working group members were in attendance at the meeting, therefore a quorum was present.
2. The meeting was called to order at 1:45 PM
3. The agenda for the meeting was presented and unanimously approved.
4. A motion was made to approve the minutes from the Spring 2016 meeting in Atlanta, GA. The minutes were unanimously approved with no objections or comments voiced. One editorial correction was made to the minutes concerning the year referenced for the previous meeting.
5. New business
6. a. A presentation was given by Edgar Trummer concerning PD level criteria during induced
voltage tests. I. The presentation triggered a discussion concerning the current PD level
criteria covered in IEEE standards. The general consensus of the group was that the guaranteed PD levels in the current standards need to be reduced.
II. Edgar Trummer made a motion to “Reduce allowable PD levels to 100 pC, allow no PD up to max operating voltage, call for a maximum PD @ 110% max operating voltage to be 20 pC, require maximum background noise level of 40 pC, and determine PD inception and extinction voltage.” The motion was rejected based on 0 votes in favor, 22 in opposition, and 4 abstentions.
III. A second motion was made by Steve Antosz to form a study group, under this Task Force, to investigate standard PD limits during induced voltage testing. The motion passed unanimously and volunteers were asked to approach the Chairperson after the meeting to participate in the study group. Volunteers are still needed and are encouraged to contact Bill Griesacker, Dan Blaydon, or Myron Bell if they would like to participate. A meeting time slot has been requested for Monday of the next Transformers Committee meeting to be held in New Orleans.
b. A suggestion was made to explore the idea of a Low Frequency Dielectric Test Guide, similar to the other companion guides that already exist for other sections of 12.90. Bertrand said this would be an issue for the SC to discuss and he would follow up with them.
Annex B

7. Old business
a. Tap changer position during induced test (survey results).
Bertrand Poulan presented the results and comments of the survey conducted after the last meeting. A positive approval rate was observed, however, there is still no agreement. Bertrand offered a few options on how we could proceed and will follow up with an updated text for the survey and report back.
b. Applying pressure inside a transformer tank during induced test (survey results)
Bertrand Poulan once again presented results and comments from the survey with an overall good approval rate. There are still too many valid comments opposing the wording and requirements, but has overall made everyone aware of the possibility occurring during factory testing. Bertrand will follow up with new wording of the proposal. Don Platts’ survey response noted that some of the new wording sounded like more like a guide. It was suggested that one option would be to undertake a low frequency test guide, and maybe for now move the text to an informative annex until a guide is written.
c. Alternative Applied test method for HV Delta windings.
No further progress, this topic was tabled until the next meeting.
d. Gassing issue for certain types of transformers with wound cores: proposal for new design test
Carried over from last meeting, this topic was tabled until next meeting.
e. Dielectric testing in the field.
Carried over from last meeting. Mark Perkins will write the details of a motion to generally require field tests on transformers with new insulation to be tested in accordance with C57.12.00 test voltage levels and transformers with other than new insulation to be tested in accordance with C57.12.90 test voltage levels. Background levels for PD can be a problem in the field and will need to be addressed.
8. This Task Force plans to meet next in April of 2017 at the Spring Transformer Committee meeting
to be held in New Orleans, Louisiana.
9. The meeting adjourned at 3:00 p.m.

B.3.6 WG - IEEE Guide for the Detection of and Location of Acoustic Emissions from Partial Discharges in Oil-Immersed Power Transformers and Reactors (C57.127) Chair: Detlev Gross Chairs Vice Chair: Jack Harley Secretary: David Larochelle Vancouver, October 25th 2016 Room: Port Alberni
Annex C Meeting Attendance The working group met at 11:00 AM. 74 persons were in the room and 20 members out of 22 were present. Quorum requirement was met. Complete attendance record is available in the AM System.
Annex D Discussions
The meeting started with the unanimous approval of the agenda (motion by Gregorio Lobo, second by Mike Franchek. The minutes from the Atlanta meeting were also unanimously approved (motion by Hemchandra Shertukde, second by Mike Franchek).
During call for patents potentially essential to the implementation of the proposed guide, Hemchandra Shertukde, Ph.D., declared his patent number US6178386. Subsequent review of the US Patent Office website indicates that this patent was recorded January 24, 2001 and expired February 18, 2013. Unless there is further information to the contrary, this patent will not be included in the Guide.
A presentation was given to the group about certain acoustic principles that will be added to the guide. Details were given about the way the mechanical energy from the partial discharges disperses in a spherical way. The energy drops with the square of the distance. It was also mentioned that oil temperature will have an effect on the propagation speed which will affect the precision of the location results if not compensated.
Different examples of wave shapes were presented with characteristics corresponding to the direct path to the sensor (oil only) and to the combined oil-steel propagation path. Internal structure of the transformer will sometimes prevent direct propagation of the waves to the tank wall. In some case, the waves will propagate through channels that will guide the waves to an exit point from where normal propagation can take place. In these cases, localisation results will change when changing the sensors position on the tank. Having the schematics of the transformer is a great advantage for identifying the possible propagation paths.
Raja Kuppuswamy mentioned that there are calculations on the waves that can be used to extract the time of arrival. Although this is usually a process correctly done manually by the users, Arturo Nunez mentioned that it can be of great use when acoustic is used in a monitoring perspective.
Annex B
Page 12 of 20
Two additions to chapter 6 were shown to the group highlighting differences from factory test to field test regarding power frequency and available sensors to acquire electrical signal.
A call was made to the group to gather examples of documented localisation cases for potential inclusion in the guide. The cases would ideally represent different contexts of localisation and highlight the procedures that led to successful results.
The group will meet again in New Orleans for the spring 2017 meeting.
Annex E Adjournment The meeting was adjourned at 12:10 PM.

B 3.7 Working Group for PD in bushings, PTs and CTs – PC57.160 WG Secretary: Thomas Sizemore; WG Chair: Thang Hochanh Meeting Minutes October 24, 2015 at 4:45 – Vancouver, BC Canada Attendees: 57 Members attending: 20/34 Rosters: Circulated for members and guests. Agenda: An agenda was presented for the meeting. Essential Patent Claims: Text was displayed and the Chair inquired as to if anyone knew of essential patent claims. None were brought up during the meeting. Minutes: Motion approved David Wallace (1st) & Pierre Riffon (2nd) Items discussed based upon comments received: A total of 17 comments were received for discussion many were editorial or minor in nature. Details of the discussion points are below. Comments accepted and which will be in the next draft:
• Introduction – An introduction will be added to the draft. • IEEE C57.13 was not in the list of references. • 6.3.1 Figure 3 text is to be updated for consistency of wording which references test taps. • 6.3.2.1 Pierre Riffon proposed text for the bushing section to match the instrument transformer
section regarding the measured PD limits once the calibration is completed. • 6.4 It was proposed to move the list of abbreviations from 6.4 up in the document to 3.2 as they
are used throughout the document. • 6.4 Shibao Zhang proposed an editorial change from ‘is’ to ‘are’. • 6.4 Shibao Zhang proposed an editorial change in paragraph 1 to match the indication of bushing
tap for consistency. • 6.5.1 Shibao Zhang proposed to add the following text to the end of the section. "Calibration
circuits in Figures 10 and 11 may be slightly adjusted to reflect the point that the ambient noise during the test can be as high as the testing circuits in Figures 5, 6, and 9. However, the calibration injection points should always be the outlet of the capacitance C1 of the test object, points A and B. “
• 6.6.1 Pierre Riffon indicated that a precision need to be mentioned to reflect the point that the verification of a valid calibration is performed at a level not necessarily at 50% of the partial discharge limit for DC bushings.
• Thomas Sizemore indicated that several figures need to be updated to improve consistency of line weights, etc.
• Pierre Riffon: Correction to figure 17 labeled as a balanced circuit (unbalanced circuit). • Figure 10: For the clarity of the figure, the chair proposes a dotted line box around the capacitor
and the square wave signal generator. • 7.2.1 Vladimir Khalin indicated that no explicit instructions were provided for the testing of line
to line VTs. • The annex 'PD Measuring Circuits' (initially annex A), covers many of the same topics as the
guide. It was decided to remove it, due to duplication of definitions and explanations • Thomas Sizemore propose an introduction to be added to the annex related to PD patterns.
The follow comments were discussed but not accepted.
• 6.5.1 Jitendra Mamtora indicated a potential error in the calibrator circuits used in the guide. • An additional pattern taken from an online monitoring system was discussed. The PD pattern
cannot be positively identified being in the bushing installed on a transformer.
Annex B

Additional items discussed: The wording of the PAR was discussed. It currently does not cover DC bushings which are in the draft document. The working group agreed to pursue a change in the PAR to incorporate DC bushings in the guide. Tom Provost indicated that he is willing to assist the Chair in this process. Motion to adjourn: A motion was presented by David Wallace and was seconded by Detlev Gross. Spring meeting 2017: The chair plans to wrap-up the draft for the New Orleans meeting and submit the Draft for approval by the WG. Date: 2016-10-25 Secretary: Thomas Sizemore Chair: Thang Hochanh

E.1 Liaison Reports
E.1.1 Voltage Test Techniques (HVTT), IEEE Standard 4 - Arthur Molden
HVTT LIAISON REPORT OCTOBER 2016, VANCOUVER BC CANADA The IEEE High Voltage Test Techniques (HVTT) Subcommittee of the Power Systems Instrumentation and Measurement (PSIM) Committee met in conjunction with the IEEE PES Fall 2016 Switchgear Committee Meeting, in Pittsburgh, PA. The meeting took place at 2PM, Tuesday October 11th, in the hotel and on line via a video web conferencing service. There were 6 members and 3 guests present onsite for the meeting, 1 member and 3 guests attending via web conference, and 1 member attending via teleconference. The membership attendance was sufficient to achieve a quorum, and the Minutes of the last HVTT meeting held in Memphis, TN in January 2016 were approved. Prior to this meeting, members of the HVTT Subcommittee made a presentation to the Switchgear Committee members and guests on Monday October 10th, which included a brief history of IEEE Standard 4, a presentation on measurement uncertainties, and a presentation on impulse parameter extraction by the k-factor method. On the morning of Tuesday October 11th, the working groups met who are responsible for the revisions of IEEE 1122 and IEEE 510. IEEE 1122 is the Standard for Digital Recorders for Measurements in High-Voltage Impulse Tests. The minutes of this meeting will be included in the HVTT minutes when published later this year. There is an active PAR for the revision of this standard, which was last reaffirmed in 2008. IEEE 510 is the Recommended Practices for Safety in High-Voltage and High-Power Testing. The minutes of this meeting will be included in the HVTT minutes when published later this year. This document was last reaffirmed in 1992, and although it is presently considered as inactive by the IEEE, it is still commonly referenced in other active standards and in work safety procedures utilized by private HV testing organizations. A PAR has been submitted for consideration at the December 2016 IEEE NESCOM meeting to rewrite and reissue this document in the form of an IEEE Guide. Both working group meetings were conducted from the hotel meeting room and also included web conferencing attendance. The web conferencing service was a new experience for this working group, and while it enables higher meeting attendance levels and more technical discussion, the service requires a more disciplined coordination of member comments, both in the room and over the web. Audio and video quality can vary during the meeting, and can be compromised by inadvertent interruptions to a comment, the results of which may require repetition of a discussion and some loss in productivity. However the overall result was quite successful. Actual Standard 4 business discussed at this meeting included: • Progress of AC voltage measurement Round Robin • Differences between IEEE Standard 4 and IEC 60060 Step Response testing procedures used in the qualification of impulse measuring systems
Annex B
Page 18 of 20
• Slightly different definitions for the peak value of an AC voltage in IEEE Standard 4 versus IEC 60060-1 • Corrections required in Table 5 of IEEE 4-2013 to correct the units given for the column specifying the water resistivity values to be used during wet tests of insulators • The need to provide more information and guidance on the use of Type B (systematic) uncertainties in the estimation of the combined expanded uncertainty, as required in the calibration of HV measuring systems made in accordance with IEEE Standard 4-2013. Finally, there was interest expressed by the Switchgear Committee in having a general IEEE Guide for Partial Discharge Measurement, as a horizontal (non-apparatus specific) document, as their former PD Guide (IEEE 1291) is expired. The HVTT Subcommittee agrees that such a guide would be beneficial, and we believe that HVTT would be the correct group within IEEE to organize its development. Following some investigation into what level of support may be available to develop such a guide, discussion of this topic will continue at the next HVTT meeting in January 2017. The High Voltage Testing Techniques Subcommittee is actively soliciting members. Should anyone be interested in joining HVTT or it’s working groups, please contact Jim McBride or Jeff Britton for details. The next HVTT meeting will be at the IEEE Joint Technical Committee Meeting in New Orleans, LA, January 8th to 12th, 2017. END A. Molden / jab 10/26/2016

4.3 Minimum Impedance voltage
“For each transformer design, the manufacturer shall determine the nominal impedance. The impedance of individual transformers shall be within the tolerance on impedance as specified in IEEE Std C57.12.00. The minimum nominal impedance shall be per Table 12 which applies to all distribution transformers with low voltage ratings 600 V and below. Two winding distribution transformers with low voltage ratings above 600 V should be designed to withstand short circuits limited only by the impedance of the transformer. There is no requirement for ratings not shown in Table 12.” A motion was made by Marty Rave and Ron Stahara to the user may specify. Motion was unanimously approved.
Annex C
3 of 14
Clause 5.1 Basic Lightning Impulse & 5.2 Dielectric Test. A suggestion was made on clause 5 that is more rating related to test levels and Clause 6 is related to the actual tests. Al Suggested that we change title of 5.1 to Basic Impulse Insulation Levels and 5.2 to Dielectric Test Levels. This distinguishes clause 5 which outline insulation level requirements from clause 6 which addresses tests. A motion was made by Ron Stahara and seconded by Steve Shull. The motion was approved unanimously
Clause 7.3 Polarity Terminal Markings. The title of the clause does not include all the content. Al suggested “The title and arrangement of this clause has been in use for many revisions of this standard. Expanding the title of 7.3 would result in a lengthy, confusing title”. Al suggested that we consider reviewing in detail for the next standard revision. No vote was taken but everyone agreed.
Clause 8.2. The angle of tilt was discussed. Al Suggested that we reject the comment and stated “The existing clause sufficiently instructs users when an angle of tilt requirement may be needed. Users may further describe the angle of tilt from vertical or horizontal”. No vote was taken but everyone was OK with Al’s suggested comment
Clause 9.1. There were three parts of this comment the first part, Al stated that “The comment does not offer a clear proposal for the revision”. The recommendation was to reject the with Al’s justification. The second part pf Clause 9.1 Al stated that “The present wording is sufficient and conveys that each transformer enclosure is limited to no more than two tests”. The recommendation was to reject the with Al’s justification. The third part of Clause 9.1, Al stated that “The proposal is not sufficiently different than the existing wording”. The recommendation was to reject the with Al’s justification. Again, Al was suggesting that we reject the comment for consideration for a future revision. There was no strong feeling or objection brought forward by the WG. No vote was taken but there was no objection to moving forward with AL’s comment.
Clause 7.1.1 The comment was reviewed by AL with the WG . . . Al Suggested that we replace Low Voltage with ALL bushings shall be sidewall type . . . Also the shaded area “zone” of acceptability was not consistent with the 1 bushing and 2 bushing. Carlos Gaytan brought up a question ...Base on discussion Al suggested we accept the comment as written... No vote was taken at the time but the WG agreed
Clause 7.2.1 ...Tap Change ...The comment was this was awkwardly worded...It was suggested that we change it to "A written caution statement to de-energize the transformer before operating, shall be located on or adjacent to the operating mechanism." Al’s suggestion was that we accept the comment. No vote was taken at the time but the WG agreed
Clause 7.2.2 ...The exact same thing... The comment was this was awkwardly worded. . . It was suggested that we change it to "A written caution statement to de-energize the transformer before operating, shall be located on or adjacent to the operating mechanism." Al’s suggestion was that we accept the comment. No vote was taken at the time but the WG agreed
Clause 7.2.6.1 Excluding the cover gaskets and insulating fluids leaks of the component gaskets activation. There was considerable discussion on pressure and pressure relief device. Carlos Gaytan discussed what was being discussed in his working group. The comment was to re-word the following sentence (excluding the cover gasket and insulating liquid leaks of component gaskets). It was suggested that we change it to (excluding the cover gasket and insulating liquid leaks of component gaskets). Al asked if there were any objections with going with the statement and accepting the comment. No vote was taken at the time but the WG agreed
Annex C
4 of 14
Clause 7.3.4. It was stated that “The location of the instruction nameplate is already given in detail per Clause 7.3.4.1.” It was suggested that the sentence be removed . . . Al stated that he agreed with the comment . . . No vote was taken at the time but the WG agreed. . .
Clause 7.3.4.1 ...The comment suggested we change “Instruction nameplates shall contain the information specified in IEEE Std C57.12.00 (see item 11 in Figure 7 through Figure 14) except that the BIL rating shall be shown for all single-phase ratings above 16 340 V. The instruction nameplate shall be in accordance with nameplate A as described in IEEE Std C57.12.00.” Al reviewed with the WG his cleaned up sentence rather than have two separate sentences, Al suggested, “The instruction nameplate type and information provided shall be in accordance with Nameplate A as described in IEEE Std C57.12.00 except that the BIL rating shall be shown for all single-phase ratings above 16 340 V”. No vote was taken at the time but the WG agreed. Al suggest that we go with this now and consider changes to future revisions.
It was agreed that we would pick up where we left off for the next meeting and vote on the recommendations all at one time.
The next meeting will be April 2017 in New Orleans.

8. Revision of C47.12.32 – Continuation of reports from Atlanta Meeting:
a. Darren Brown – comparison of FS-40 bulb versus UVB-313EL
Annex C
5 of 14
Summary of discussion & conclusions:
Darren presented a Howard Industries test report comparing FS-40 bulbs with UVB-313EL bulbs. The test was performed using a UV accelerated weathering chamber and brand new bulbs.
The findings were that grey panels were more impacted with the UVB bulb than green panels. The green and grey panels acted differently between the two bulbs indicating that there is a difference between the two bulbs using this basic test. All test panels passed the test.
Dan Mulkey commented that we need a quick test which will pass good units and fail bad ones and is also reflective of real-world environments.
It was noted that a letter was received from one supplier of the FS-40 bulbs indicating that they were not being discontinued as indicated by a ballot comment.
It was also noted that if a change in lamps is made, new baselines will need to be established.
The question was asked if any testing had happened using samples with black paint. Darren mentioned it likely has been in the past but we don’t have the results documented.
b. Tom Holifield – citation of paper on 409 stainless steel
Summary of discussion & conclusions:
Tom presented a historical paper which investigated suitable tank materials. The investigators looked at 3 types of stainless steel: SS304, SS316 and SS409. The paper concluded that SS409 was the best material to use. It discussed that SS316 performed better with respect to pitting corrosion from sea water, but was more susceptible to stress corrosion.
9. New Business
a. Maria Lamorey – PPG comparative QUV testing on FS40 bulbs
Summary of discussion & conclusions:
Scott Abbott of PPG presented a comparison study between the QUV-A and QUV-B lamps.
The study indicated that in tests using QUV-B testing, powder systems did not perform as well as liquid systems, but this does not necessarily correlate to real world test data based on tests performed in Florida. He explained that the QUV-A bulb mimics sunlight better than the QUV bulb.
The study made the following conclusions:
• QUV-B testing is too variable and depends very much on irradiance (power output) level of the bulbs
• Current QUV test is not irradiance controlled • QUV-B testing may eliminate a system which is cost effective and suitable for
IEEE end use • QUV-A mimics real world (Florida) better than QUV-B and is more reliable if
specification (gloss retention and test time) is set correctly • QUV-A can still “weed out” poor performing systems in a short time period • QUV-A bulbs would still use the current QUV cabinets used today
Annex C
6 of 14
• Recommend the use of “irradiance control” on new QUV hardware moving forward
• Irradiance control cabinets are easier to run and can provide significant savings on bulb costs
• Payback from cost saving can often be within one year
Scott recommended the following settings for tests: • 0.9 irradiance, • 1000 – 1500 hours minimum, • 80-90% glossary retention
After this presentation, a prolonged discussion took place:
The point was raised that the time required for QUV-A testing may be longer than current testing duration, which is a concern for manufacturers. Alan Wilks mentioned that QUV testing is not labor intensive since it can be left alone after the test is setup, so it can be used for “screening tests” of materials prior to running other types of tests.
Brian Klaponski mentioned that the ozone layer changes over time and asked how that would influence the “Florida test” in the report. Scott replied that there is a lot of Florida data over the years and we may need to investigate if there has been a change in performance over the years.
The question was asked if the presented test data was sufficient to develop the standard, or if further testing was required. Ron Stahara suggested that if we feel that further testing would be of value, we ought to pursue it, even if we don’t use it for this version of the document.
Further testing using black paints may also be helpful, since this color is also used for underground transformers. Brian Klaponski proposed that there is not currently an issue with black paint, so it is not worth spending further time testing it. It was asked if PPG could repeat the test using black. They indicated it would be best if samples were provided by manufacturers. Alan Traut mentioned that Power Partners could provide all three colors.
It was suggested that manufacturers should send samples to the lab for further testing, instead of paint manufacturers providing test samples to ensure the testing was done on the actual substrates.
It was also mentioned that a defined irradiance needs to be set for further testing moving forward.
There was a discussion about whether the impact of the coating effects performance or aesthetics. It was suggested that durability, not aesthetics, must be the purpose of this standard.
It was suggested that underground transformers may not need as long of a coating lifetime because they are installed below surface. However, they may wait in the yard for a long time prior to installation. In some cases they are also installed above ground.
There was further discussion about the impact of percent gloss. Brian Klaponski asked if a higher percent gloss yielded higher durability. Scott Abbott responded that generally, a higher initial gloss tends to give higher durability or better gloss retention than a similar product at lower gloss. Tom Holifield mentioned that they have coatings with low gloss that are better than coatings that do have gloss. Scott clarified that
Annex C
7 of 14
different families will behave differently, so one type of coating with a high percent gloss may not perform as well as a different type of coating with a lower percent gloss. If comparing similar types of coatings, generally a higher percent gloss results in higher durability.
It was noted that percent gloss impacts aesthetics, durability and thermal characteristics. It was asked if emissivity is a function of percent gloss. Al Traut mentioned that radiation heat transfer doesn’t play a large impact in a vault. It was also noted that both percent gloss and irradiance should be specified in the standard.
On a pad-mount transformer, a higher gloss shows irregularities more, so lower gloss may be preferred by some manufacturers. Some manufacturers prefer high gloss.
It was noted that in C57.12.40, the specification simply states a “dark color”, and suggested that this be more thoroughly defined in C57.12.32.
There was a discussion about how change in percent gloss should be described. Dan Mulkey suggested that since gloss is measured in percentage, the change in percent gloss should be a subtractive difference, not a divisive difference. For example, a change of 0.02 to 0.01% is a 0.01% change, not a 50% change.
Carlos Gaytan clarified the difference between percentage points and percentage:
• Percentage point loss: the subtracted difference between initial and final percentage
• Percentage loss: the divided percent between initial and final percentage
In the paint industry, percent change in gloss is usually based on percent gloss retention of the initial gloss (divisive, not subtractive). For example, the gloss must remain above 90% of the initial gloss.
Brian Klaponski stated that if a higher gloss provides better durability, we should specify a higher gloss.
It was noted that the response to the ballot comment stating “Working to see if we have an equivalent – potentially QUVA-303 with lower irradiance level” should state QUVA-340 instead of QUVA-303.
A motion was made by Mike Thibault and seconded by Alan Wilks to change the language in paragraph 4.5.6 from “Expose two test panels” to “Expose three test panels”. The motion passed unanimously.
A motion was made by Ron Stahara and seconded by Mike Thibault to change from two to three test panels for all long-term tests. The motion passed unanimously.
A task force was formed to develop proposed final wording for paragraph 4.5.6 Ultraviolet accelerated weathering test (QUV). The following attendees joined the task force:
• Scott Abbot, PPG Industries • Darren Brown, Howard Industries • Martin Rave, ComEd • Maria Lamorey, PPG Industries • Rebecca Giang, Sherwin-Williams Co. • Mike Thibault, PG&E
The following members agreed to provide coating samples for further testing.

C57.12.34 – Three Phase Pad-Mount Transformers – Ron Stahara
Ron Stahara presented the following minutes from the working group meeting on October 24, 2016 at 3:15 p.m. with 71 in attendance.
Ron Stahara called the meeting to order and introductions were made. The rosters were circulated. The names of those in attendance are recorded in the AM system. To establish a quorum, a members list was displayed on the screen and those who saw their names were asked to hold up their hand. From this count of hands, it was determined that a quorum was established. A motion was made by Gael Kennedy and seconded by Jerry Murphy to accept the agenda as shown. The motion pasted unanimously. The Patent Slide statement calling for Essential Patent Claims was read and none were brought up at this point. A motion was made by Gael Kennedy to accept the minutes of the Spring 2016 meeting as written. This was seconded by Cory Morgan. The motion pasted unanimously.
Ron Stahara stated that the PAR had been approved.
Ron went on to state that we had two items that we need to pursue on the new standard. The first is to review the exiting standard for any updates from other standards that have recently been published. These would include IEEE C57.12.00, IEEE 386, and others that are pending such IEEE C57.12.39. Ron suggested to the Working Group that a taskforce be created to do this. The Working Group agreed and Dan Mulkey was appointed as chair and the following individuals were added as members; Steve Snyder, Carlos Gaytan, Brett Chrysler, and Justin Pezzin. This Task Force would work on this during the next few months and report their progress at the spring 2017 meeting. The second item would be to review the figures for clarity and correctness. Again a Task Force was suggested to do this work. The Working Group agreed and Gary King was appointed chair and the following individuals were added as members; Dwight Parkinson, Scott Dahlke, and Alex Macias. This Task Force would work on this during the next few months and report their progress at the spring 2017 meeting.
The Working Group had discussed how to present various items that users purchase on these units. These could be classified as accessory items that are provided on or in the transformer and should not be considered a part of the standard. This document would be provided as informational for an unsophisticated user. This suggestion resulted in a rather lively discussion. Some of the comments were concerns about liability or attempting to provide a transformers 101 document. Other comments were that this was a good idea to help these unsophisticated users to understand the need for items like sight glasses, gauges, under-oil fuses, and their
Annex C
9 of 14
applications, etc. This resulted in a motion by Brian Klaponski and seconded by Alex Macias to make an “Attempt to make an informative annex for application of accessories as they relate to this standard”. This motion pasted unanimously. Steve Shull volunteered to gather these items into some type of outline to be presented at the next meeting. After this, Brian Klaponski, stated that he was not sure but with this addition we may have an Essential Patent Claim. He believed that the “third door” was a patent that was held by ComEd created by Martin Rave and Tom Callsen in 2004. Tom Callsen confirmed that this was true. Steve said he would send the LOA informational letter and form to Martin Rave since he was remaining person of the two working for ComEd.
The last comment of the day was made from Aniruddha Narawane concerning a couple of items that seem to be in error in the current document and should be reviewed for correctness in the next version. He stated that he would send this detail to Steve Shull so that he could include it correctly in the minutes. It is as follows:
The yellow highlighted items enumerate the concerns.
With this, the meeting was adjourned, Stephen Shull recording.
C.2.4 C57.12.36 – Distribution Substation Transformers – Jerry Murphy
Jerry reported the working group met Tuesday, October 25, 2016 at 1:45pm with 48 people in attendance.
Jerry Murphy called the meeting to order at 1:50 PM. Introductions were made. The names of the members were projected on the screen. By a show of hands the quorum was reached by having 12 out of the 21 members present. The approval of the agenda was moved by Terry Martin, seconded by Steve Schroeder. The motion was approved. Steve Shull made a motion to approve the minutes of the Spring 2016 meeting in Atlanta; Gael Kennedy seconded, and the motion was approved.
After Jerry asking the question, there were no patent claims brought up to the working group.
Annex C
10 of 14
Jerry reviewed the comments from the latest ballot recirculation. The first was a general comment from Peter Balma, indicating that a number of changes approved by the WG were not reflected in the latest draft. Jerry proposed to accept this comment, and receive from Peter a list with the approved changes, in order to add them to the document. Three comments related to corrections to figures and metric conversions were accepted. Next a comment about figures in Annex A showing dimensions in inches was discussed. Gary Hoffman stated that since this was an informative annex, the use of dimensions in U.S. Customary units was allowed. The disposition of the comment was to accept it and include a note indicating that the dimensions were in inches.
Next the comment about the reference to PC57.12.39 was reviewed. It was agreed to keep the reference to Draft 4 of this project standard, since it had been balloted. The last comments related with editorial corrections were reviewed and accepted.
Gary Hoffman made a motion, seconded by Steve Shull, to permit the chair to incorporate the changes that should have been included in the document, and initiate a ballot recirculation process. The motion was approved unanimously.
The next WG meeting will be in April 2-6 in New Orleans, LA.
The meeting adjourned at 2:50 pm., Carlos Gaytan recording.
C.2.5 C57.12.38 – Single-Phase Pad-Mounted Transformers – Ali Ghafourian
Mike Faulkenberry presented the following minutes from the working group meeting on October 25, 2016 at 1:45 p.m. with 59 in attendance. The meeting was called to order at 1:45 p.m. by Ali Ghafourian.
A quorum was established with 22 of 27 working group members present.
The agenda for the meeting was presented and unanimously approved.
The minutes of the spring 2016 meeting in Atlanta have been posted on the web site since shortly after that meeting for the working group members to review. There were no suggested changes to the minutes and a motion was made by Justin Pezzin and seconded by Marty Rave that the meeting minutes be approved. The approval of the minutes was unanimous.
A call for essential patents was made as required using the statement provided in the general session. No essential patents were brought forward.
The status of the document was discussed. The ballot on Corrigenda 1 correcting an error in Figure 1 of the published standard has closed. 89% of the ballots were returned. 100% approved. The document is currently at RevCom. A PAR cannot be submitted until the corrigenda is published, and Ali announced his intentions are to file for a PAR when he is permitted to do so.
A discussion was begun of proposed changes to be considered for inclusion in the next revision of the document.
• Ali proposed that two new tables be added to the document. One for dual voltage ratings would be added as Table 4 and a potential table was presented for review. A question was raised as to why 34.5 kV dual voltage units were not included. Ali answered that the attempt was to match a similar table in C57.12.20, and it does not include 34.5 kV as that is not a common application.
Annex C
11 of 14
• Another table for minimum percent impedances was proposed and would be added as Table 5. There were no objections to adding the table, but the consensus was that the table needed to match the table in C57.12.20. The proposed table, as presented for review, did not match C57.12.20 but will be changed to do so.
• Mike Faulkenberry stated that he had received an email from a user asking why there was no table with voltage ratings for live front transformers while there was a table (Table 3) for dead front transformers. The first two columns of Table 3 are actually voltage ratings for both live front and dead front transformers. The remaining columns of the table are ratings for dead front bushings. The working group was asked if we needed to consider separating out the transformer ratings into one table and the dead front bushing ratings into a separate table, similar to Table 2 for live front bushings. After some discussion, the decision was to leave the table as currently published.
• A question was raised as to why the Phase-to-Ground clearances in Table 2 were smaller than the Phase-to-nonhygroscopic insulating barrier clearances. It was noted that this was actually only true for the first three lines of the table. After comparing this table to the similar table in C57.12.34, it was determined that the first three lines should not have contained values. They should have been grayed out as in C57.12.34 to indicate that values are not applicable for these system voltages. This will be corrected in the next revision.
• Ali asked the working group to consider if we wanted to include in the next revision any of the transformer components. The current scope states that components are not covered. These could be included as an informative annex to the standard. A task group was selected to formulate a list of components for possible consideration and provide the reason why they should be addressed. The members of that task group are Giuseppe Termini, Wes Suddarth, and Craig DeRouen.
• A question was raised as to the potential for inclusion of phase-to-phase voltage ratings. Ali responded that the use of those voltage ratings is not common and is why they are not included in the standard.
Mike Faulkenberry, Vice-Chair, announced that he will be retiring in April of 2017 and will most likely not be attending future meetings. Therefore, the working group will need a new Vice-Chair, preferably a utility member, to take his place. The working group members were asked to consider volunteering for the position.
The meeting adjourned at 1:45 pm.
Submitted by Mike Faulkenberry.
Steve appointed Martin Rave as the new vice chair for the working group.
The Distribution Subcommittee recognized and applauded Mike Faulkenberry for his many years of dedicated service and wished him all the best as he retires.
C.2.6 C57.12.39 – Tank Pressure Coordination – Carlos Gaytan
Carlos reported the working group met Tuesday afternoon at 4:45 p.m. with 44 in attendance. The meeting was called to order at 4:45 PM. Quorum was reached by having 22 of 30 members present. The approval of the agenda was moved by Al Traut, seconded by Ron Stahara, and the motion was approved unanimously. The approval of the minutes from the Spring 2016 meeting was moved by Dan Mulkey, seconded by Jerry Murphy, and the motion was approved
Annex C
12 of 14
unanimously. No patents were declared. On chair remarks, Carlos informed that a PAR extension was requested, and it was expected to be approved at the Dec. 7 IEEE-SA Standards Board meeting. The question about essential patent claims was posed. The results of the ballot of Draft 4 were presented. They were successful, with a 95% approval rate, and a total of 32 comments.
The group then reviewed the comments and proposed resolutions. First question was a disapproval vote from Gary Hoffman. The concern was related with the clarity of the purpose of the document related to distribution transformers. After some discussion related with the risks associated with modifying scope and purpose on approved PARs that may invalidate the ballot, Gary agreed with the proposed disposition. Dan Mulkey suggested that any editorial changes we thought were required, should be made before submitting a new draft for ballot.
Next the group discussed a negative vote related with Sect. 3 definitions, proposing to simplify the text. After some discussion, Dan Mulkey moved to remove the Nominal Pressure definition from the document. Steve Shull seconded. Robert Stinson offered a friendly amendment to add to move the text from the current text of the definition into sect. 4.2. The amendment was accepted, and the motion was approved unanimously. The ballot disposition changed to Revised.
Next the comment to modify the definition of Rapid Transient Pressure was reviewed. It was accepted as Revised. Comment about definition of Pressure-vacuum bleeder was discussed. It was agreed to modify the text as per the comment, and changing to “air / gas” in last sentence.
Next comment was related with section 4.3.1, applicability of fault current capability test to overhead and submersible transformers with round tank construction. A comment was made that trying to incorporate test criteria for rectangular tanks should be left for a future revision. Group believed that the current language was acceptable.
Next the comment related with the use of words distortion vs. deformation. There was agreement that deformation was a more accurate term to use. Dan Mulkey made a motion to change distortion to deformation, only if we were able to change the purpose of the PAR and the document without invalidated the ballot. Ron Stahara seconded. The motion was approved unanimously. Steve Shull later identified that the purpose could be changed.
Next comment discussed was on PRV location in section 4.2.2.3. It was concluded that reference to tank wall was not needed in the first part of the statement. The text was changed to Draft 5.
Near the end of the meeting, a suggestion was made to create a ballot resolution task force in light of the need to move forward quickly to complete before the end of the 1 year PAR extension. Carlos will form the task force in order to complete the review and resolution of the comments prior to the next meeting.
The next WG meeting will be in April 2-6, 2017, in New Orleans, LA
The meeting adjourned at 5:55 pm, Justin Pezzin recording.
Carlos concluded his report saying he would be requesting a one year PAR extension.
C.2.7 Task Force on Transformer Efficiency and Loss Evaluation – Phil Hopkinson
The Phil Hopkinson welcomed the members to the meeting and noted that the high attendance (129) indicted the level of interest in the topic.
Annex C
13 of 14
This was the first meeting of the task group so there were no minutes to approve. The agenda was approved as submitted. Since this was the first meeting a quorum verification was not needed.
Presentations for the meeting from Mr. Hopkinson and Mr. Mulkey have been uploaded to the IEEE Transformer Committee Website under Distribution Transformers Subcommittee.
Background
The DOE Energy Efficiency rules will be due for renewal or revision by January 1, 2022. The current loading is estimated at 50% of nameplate rating load for medium voltage transformers and 39% for low voltage transformers. There is a need for real data to replace these estimates. The quality and availability of data have benefited from the expanding use of smart meters. Utilities may be capable of providing data on transformer loading broken down into load types, geographic locations and other useful categories.
PG&E Data
Dan Mulkey provided the perspective from PG&E who have extensive loading data that has been made public on their website. He presented data for the 2006 which was noted for a heat storm that caused a great number of transformer failures. His report has been uploaded and made available to members.
Mr. Mulkey reported that the loading RMS was very close to the 50% used by DOE.
Transformer capability was based on limits of the following:
a) Thermal – Hot Spot ≤ 190°C – Top Oil ≤ 110°C
b) Life loss – Total Aging ≤ 13140 hours
• 5% of expected life / 1.5 years of aging in one year c) Voltage regulation
– Voltage drop < 6.5 volts for transformer secondary – Flicker drop < 8.0 volts for transformer, secondary and service
He noted that typically distribution transformers are run to failure or run until a problem is encountered. He explained that the cost of a transformer is outweighed by the installation costs so replacement is preferred to relocation. PG&E’s experience showed that most transformers have an average life of 40 years with 2.5% of total installed being returned each year. Distribution transformers are pulled from stock so there cannot be any optimization when picking the transformer for the application. This is in contrast to power transformers which are purchased for a specific location even though these can be redirected to other locations as urgent needs arise.
The chair asked members representing utilities if they thought the disclosure of data similar to that from PG&E could raise conflict of interest concerns for them. Only one individual said that it might be a concern. After some discussion, it was decided that a template should be developed to provide a method in which this information could be provided. The work group chair will create a task force to develop this by the spring 2017 meeting, which will be held in New Orleans.
The meeting was adjourned, Gerard Winstanley recording.

C.3 Old Business
• None
C.4 New Business
• Impulse Test Concepts – Phil Hopkinson
Phil gave a presentation (posted to website) on how it is time our factory impulse tests were upgraded. Phil gave examples of how factory tests are not achieving as much winding stress as field conditions with the troubling fact of failed windings from the field returned to the factory and passed the standard impulse test. BIL tests for dry type transformers are reduced compared to liquid filled with no basis today.
Phil concluded that impulse testing should add stress with higher BIL levels, faster front waves, higher chopped waves, longer switching waves and specific open terminals in addition to shorted terminals of non-tested windings.
• Hemchandra Shertukde commented to the subcommittee that solar transformers needed to be addressed for tank pressure issues.
• Brian Klaponski asked for clarification around patent claims requests in working group meetings. Gary Hoffman clarified that if a claim is made then a letter of assurance (LOA) must be requested and this should be recorded in the minutes. There is no need for discussion in the meetings as it is a matter for PatCom. There is a listing of all filed LOAs on the PatCom web page.
C.5 Chairman’s Closing Remarks and Announcements
Steve had no closing comments to the SC except to see them in New Orleans in spring of 2017.
C.6 Adjournment
Steve adjourned the meeting as provided in the meeting agenda at 10:47am.

D.3 Working Group/Task Force Reports The next order of business was the presentation of the reports of the various working groups and task forces. See the following sections for the individual reports:
D.3.1 IEEE PC57.12.01 - Dry Type General Requirements Chair Casey Ballard
The working group met in the Port McNeill Room of the Sheraton Vancouver Wall Centre Hotel The meeting was called to order at 1:45 PM by Chairman Casey Ballard The meeting was convened with 34 participants, 15 of them requested membership. Quorum was reached as this was the first meeting of WG. The attendance was reported in the AMS. Introductions were made by all participants. The agenda was approved unanimously being no negative votes.
Annex D
Page 2 of 14
The Task Force minutes of the Atlanta, GA, March, 21, 2016 meeting was approved unanimously being no negative votes. The chair made a call for patents using the request recommended by IEEE TC. No patents were claimed. Old business
- The chair noted that he has distributed the Draft 1 of the document well in advance of the WG meeting and all changes that TF agreed upon in Atlanta Spring 2016 meeting were included in this Draft.
- Then WG started discussion on the open questions. a) Cooling ratings – Section 5.1
• The chair mentioned that C 57.12.01 uses the cooling indexes that are different from IEC and oil type IEEE standards. Harmonization with IEC was proposed and supported by the TF.
• The usage of IEC terminology is straight forward with the exception of the case of sealed transformers. After discussion and several proposals, D. Patel volunteered to review IEC and CSA standards and develop a proposal for the WG consideration.
b) Words “power” and “kVA” in the text of the Standard. • C57.12.00 revision uses “kilovoltamperes” when describing transformer’s capability. • The motion was made by D. Walker: “Replace word “power” with word “kilovoltampers”.
This was seconded by V. Tendulkar. In the discussion, P. Hopkinson proposed to use the full word just in the titles of the Chapters and to use the abbreviation ”kVA” otherwise. The motion was amended and WG approved the amended motion unanimously.
c) Maximum system voltage – Table 5. • Suggestion was made to add the column “Maximum System Voltage” to table 5. After
discussion about what maximum system voltage means, the differences between the system voltages in the USA and Canada, M. Gromlovits made a motion that was seconded by J. Antweiler: “Include maximum system voltage column in Table 5, but revise the values of the maximum voltages. In the discussion, R. Thompson and C. Ballard agreed that to have the clear separation of systems by maximum voltages is a positive improvement that will help in the selection of the transformer voltage class. Motion passed with 15 members-to-be voted for, 1 abstained (D. Patel) and no negative votes.
• V. Tendulkar volunteered to review IEC standards and provide the proposal for the WG consideration.
d) Fuzzy figures 3 and 4. • Updated figures are available and will be included in the next Draft.
e) SC thermal limits – Table 15. • R. Marek provided the proposal to change the temperature limits for Cu and Al
transformer conductors that are in line with IEC. • The comment was made that 200 deg. C limit for Al conductor is too low as it is on the
level of normal loading winding temperature. WG agreed with this. • D. Patel commented that IEC based their limits on the consideration of the potential
cracking of the cast resin insulation. • R. Marek and D. Patel agreed to review the physical properties of the different Cu and Al
alloys used in the winding conductors and provide the proposal for the WG consideration. f) SC thermal limits – Section 7.1.

• R. Marek proposed to use IEC calculation equations for the average winding temperature after SC instead of IEEE ones from section 7.1. He thinks that the results between IEEE and IEC are pretty close, but IEC version is much less cumbersome.
• D. Walker agreed with this and volunteered to provide an example comparing those 2 calculation methods.
• C. Ballard will request whether the IEC equations can be borrowed for C57.12.01. g) BIL – Table 5.
• The chair informed about a survey on proposed changes in main BIL levels: 95 kV vs. current 60 kV or 75 kV vs. 60 kV for 15 kV transformers; 75 kV vs. current 45 kV for 8.7 kV transformers. Out of 14 received replies, votes split 50/50.
• D. Patel composed the Table with comparison of the correlation of LF test voltages and BIL test voltages with nominal system voltage for different voltages. He showed that the change to 95 kV BIL for 15 kV system and to 75 kV BIL for 8.7 kV system would place the correlation coefficients for the respective voltage systems out of a normal range. That is why he voted against changes, but may agree with moving from 60 kV to 75 kV level.
• P. Hopkinson commented that traditional rational behind the selection of BIL test voltages is not sufficient anymore as we discuss how to improve a reliability of transformers (both dry-type and oil-type). Many failures can be associated with fast switching transient voltages and respective resonances; BIL test may not address this type of the stresses.
• Phil made a presentation on the failure investigation of several transformers feeding data center. The root cause was identified as a voltage resonance at switching transient voltage. The factory BIL test is done with no load and wasn’t generating the same resonance. Test decisions need more discussions.
• Protection solutions are available to prevent or mitigate fast transients and resonance: shielding, damping, circuit energization / de-energization control.
• Phil thinks that dry-type transformers may have the same test levels as oil-type transformers of the same voltage class, but Phil agrees with D. Patel and V. Tendulkar that the increase of the BIL test level alone may not solve the discussed problems.
• Phil will continue the discussion on the adequate transformer testing in other Sub-Committees.
• J. McBride informed that Dielectric Test Subcommittee will continue the discussion aimed to address the fast transients and resonances in transformers: maybe test with steep front wave, etc.
• The chair proposed separation the discussion on the test modification (which this WG will follow) from our current decision on the BIL levels in Table 5 of the standard. We would need to agree on what we want to do until the next WG meeting in Spring 2017.

D.3.2 IEEE PC57.12.60 - Dry Type Thermal Aging Chair Roger Wicks
The meeting was called to order at 9:30 AM by Chairman Roger Wicks. Introductions were made and attendance sheet was circulated. The meeting was convened with 34 people in attendance / 8 members present (No Quorum reached.). Two of the guests present requested membership. Because of lack of Quorum, the minutes from spring 2016 WG meeting could not be approved. The Chairman will circulate these unapproved minutes to the members of the WG in an effort to approve minutes electronically. The Chairman reviewed the proposed Agenda. The Agenda was slightly different than the one circulated earlier to the WG in that it added the review of “essential patent claim”. The Chairman posted the new “essential patent claim”. No one at the meeting presented any essential patent claims.
Old Business / Review of last meeting:
1. Partial discharge as a trending test Summary of problem - Partial Discharge measurements can be used as in indication of movement within a winding or separation of solid insulation elements leaving voids or air leading to highly electrical stressed areas. This can be especially important when testing solid cast coils. At last meeting the WG discussed PD as an indicator of transformer health and its use as a trending test to be included in the Annex of the document. Tim Mai had volunteered to submit a proposal toward this end. The Chair presented Tim’s’ proposal, and summary of its review by the WG is as follows.
• The Chair commented that the written proposal reads more like a requirement, as it describes Pass/Fail limits and was suggested to be in main body of document.
• Dihru Patel commented that PD measurement may be influenced by environmental factors such as temperature. Chair agreed that the standard in general may not always include the level of detail needed to conduct tests by someone not in transformer industry and who does not routinely conduct these types of tests.
• The WG agreed that that submitted document is a good start for discussion on PD, but we should plan to limits its use to data collection (trending) at this point in time.
2. Major Insulation materials and method for changes Summary of problem - 12.60 currently defines how to evaluate a new insulation system, but does not have any direction for how to modify one.
• Reviewed a proposal for an updated list of materials that would be considered as Major insulation. The biggest change to this list is the inclusion of Varnish as a Major. Previously it had been considered a Minor insulation, and changes were allowed using Chemical Compatibility Testing (CC) aka Sealed Tube Test.
• Reviewed a proposal by Solomon Chaing (flowchart) that utilized a method of chemical analysis to determine if a material can be substituted. (If materials is shown to be chemically the same using DSC, TG, IR, it may be substituted without any additional testing.)
Annex D
Page 5 of 14
• Casey Ballard noted that the exact criteria used by UL to determine chemical equivalency is not well identified. The WG agreed that this must be better defined prior to adding this proposal into the Working Draft of the document. He will work with Mark Raymond of UL to get clarity on this.
3. Ratioing up or down from a test Electrical Insulation System (EIS) that was tested at a
particular BIL level a. Casey Ballard had volunteered to review proposal as last meeting. He determined that
ratioing down may be feasible, although ratioing up would not. Details would be presented at 12.01 meeting, as this is an issue being addressed in this standard. Thought that 12.60 would refer to 12.01 when dealing with this issue.
b. Casey also agreed to develop an example which could be included in the document (for ratioing down).
1. Extension of cold shock testing A discussion regarding the possible extension of Cold Shock testing to all types of dry-type transformers was held. Currently cold shock is only required for solid-cast and resin-encapsulated transformers only.
a. At spring meeting, a motion was approved to modify Clause 4.6, striking reference “solid-cast and resin-encapsulated designs only” in the working Draft document.
b. Mark Gromlovits noted that adding this requirement would require manufacturers to have special test equipment.
2. Review of IEC 61857-41 Document has been approved as a new item work proposal, and has been assigned to Working Group 6 (Insulation system testing) of IEC TC112. During recent meetings in Frankfurt of TC112 and TC14, this document was broadly discussed, and a taskforce has been proposed for work between IEC TC112 and IEC TC14 personnel. It was also stated (by TC14), that this work should take into account IEEE C57.12.60 wherever possible.
• Broad discussion regarding dielectric strength used to evaluate new EIS with proposed IEC test proposal, and its lack of ability to take into account power frequency and partial discharge found in an actual transformer.
• Rick Marek proposed that it is difficult to use a model to simulate an actual transformer. • Dhiru thought there was some merit to the new IEC proposal, but that an additional
(single point) test on actual full size transformer may be needed. • Chairman suggested that the IEC test may be useful as a replacement to Sealed Test as
method to approve changes to a system. • A call for volunteers was made for membership in IEC taskforce to review how new
proposed 61857-14 document between TC 112 and TC 14. Casey Ballard, Rick Marek and Ashley Reagan volunteered to participate.
The meeting was concluded at this point due to no more time. It was confirmed that the WG would meet again at the spring 2017 Transformer Committee Meeting in New Orleans.

• Tim-Felix Mai’s proposed by email that we consider adding language about transformers with load tap changers (similar to C57.12.00 and C57.12.90). Casey Ballard will bring up in new business in 12.01. If C57.12.01 adds LTC language then C57.12.91 will add LTC testing language.
• Tim-Felix Mai proposed by email that the corrections for altitude in C57.12.91 Section 11.7.3 were inconsistent with both C57.96 and IEC 600076-11. In fact, the corrections are 10X smaller in C57.12.91 than in either of the other sources. Tim Proposed either correcting the formula in C57.12.91 or simply adopting the simpler language from the IEC and C57.96 sources. It was also pointed out that the reference for this issue should be in C57.12.91 which is a standard rather than C57.96 which is a guide. After discussion it was agreed by members present to adopt the language from C57.96 for corrections for altitude in the case of testing <=100m and operation >1000m and also the case of testing >1000m and operation <=1000m. Because of the lack of a quorum this with be balloted by email.
• Casey Ballard presented some issues that had been mentioned at previous meeting but where no decisions were made:
o There is no mention of environmental testing in either C57.12.01 or C57.12.91 that is equivalent to IEC C or E ratings and some customers are asking for this. In those cases they are using IEC standards since no IEEE standards exist. Casey Ballard to bring up this issue in the next C57.12.01 meeting. If C57.12.01 add these test requirements then C57.91 will need to add test definitions. In the interim we will review the IEC CD and existing standards to better understand the requirements in the IEC standards. If we
Annex D
Page 7 of 14
adopt these requirements it was felt that we should be similar to the IEC requirements. It was felt that these tests would fall into the “other” test category and could be put into an annex to C57.12.91
o There was previously a suggestion that C57.12.91 specify how to do temperature tests with a harmonic load. It is mentioned in other standards such as C57.18.10. After discussion the members present agreed that this should not be in C57.12.91 and that it was not a practical and cost effective test to do. Especially given the wide variety of harmonic spectra that might need to be simulated. This will be settled by an email vote.
With no further business, the meeting was unofficially adjourned at 5:41 pm. The Working Group will meet again at the Spring 2016 meeting in New Orleans.

Old Business:
1. The existing Scope and Purpose sections of the C57.16 standard were discussed. The following comments were made:
a. On the second paragraph, the Scope states that: “with some restrictions” the standard is applicable to filter reactors, and other types of series-connected air-core reactors. Clarification on the specific restrictions is required in order to address and remove such restrictions.
b. The Purpose of the standard also refers to “some restrictions” in the application of the standard to filter reactors and other types of reactors.
c. The list of devices for which the standard does not apply need to be revised to remove “Arc Suppression Coils” since they already included in the neutral grounding devices category. Also, year of the standard should be removed from the references in the Scope section.
d. The Scope refers to the annexes within the standard that should be removed. e. The inclusion or not in the Scope of converter reactors used in the AC side of multilevel
converters needs further discussion especially for MV-DC applications.
2. Open item: Charles Johnson volunteered to compile meeting minutes from old meetings related to the 2011 revision and send them to the Chair as background information and to share the existing recent history on the C57.16 standard with others. Carry over to next meeting.
3. The Chair will request from Ms Malia Zaman (Standards Program Manager) the MSWord document version of the 2011 revision in order to start the changes. The document will be distributed to the WG Members and Guests before the next meeting in New Orleans.
4. A volunteer for the role of Secretary was requested at the meeting. The position remains open and a request will be done at Subcommittee level for a volunteer.

This was the first meeting as a WG with 40 in attendance and 13-16 requesting membership. Introductions were made and the patent call resulted in one claim by H. Shertukde for patent # 6178386. P. Hopkinson requested an addition to the agenda concerning the rationale for establishing 10 pc as the limit for cast coil transformers. A motion to approve the amended agenda was made by M. Gromlovits and seconded by R. Ballard. Having approved the addition, the Chair explained that the scope of the document was for procedure only and limits were given IEEE Std C57.12.01. Therefore the agenda addition was out of scope for this document. Agenda:
• Welcome & Chairs Remarks for First Meeting of WG
• Introduction of Attendees – request for membership
• Approval of Agenda
• Call for patents
• Review of Scope & Purpose
• Other Transformer Committee Documents re PD
– C57.113- 2010
• Scope and Purpose Statement for revised C57.124
• Submittal of PAR
• Next steps
• New Business
– Discussion of PD acceptance levels
• Adjourn
In the Chair’s remarks: • He noted that the document was last revised in 1999 and then reaffirmed in 2004, which is a long
time ago. When the PD limits were reduced recently to match more closely with IEC standards, the SC requested that the referenced procedure, C57.124 be revised to make sure the new requirements could be supported by the test procedure.
• He reviewed C57.12.01 changes in limits and the added procedure • All members will receive a copy of C57.12.01
o D. Gross noted that IEC 60270 was revised this year and the upper cutoff frequency was changed from 500kHz to 1MHz.
• The scope and purpose defined in last TF meeting was reviewed o Approved by SC and Committee o Key was wide band apparent charge
• J. Britton is HVTT chair and compared IEC to IEEE o Group met to develop PD document for general apparatus o May include diagnostic pattern recognition o Will need support from equipment manufacturers and looking for interest and support o This is a parallel group
Annex D
Page 10 of 14
• A. Naderian proposed adding on site testing as part of scope noting this is requested more especially for very large dry units and possible establishing TF
o Chair did not think field testing should be included and that it may fit better in C57.152 • J. Britton then qualified that pattern recognition would be general for all equipment and not
specific to transformers o D. Gross added these would be generic patterns
• B. Larzelere noted TC met in Frankfurt two weeks ago and it was decided that 60270 needs to have pattern recognition added to that document and that there is a lot of information from a CIGRE study group. As an example a cable showed 100pc but was actually due to connections and not the cable insulation.
• Chair said PD on bushings and instrument transformers, C57.113 has patterns in an annex and specific to the apparatus. What is needed is generic patterns.
• T. Hochanh noted that it is important to obtain the pattern at the inception voltage…. And suggested referring to the PD in bushing and instrument transformers standard.
o The Chair noted that the patterns in this document are quite generic and could be added to C57.124
• H. Shertukde stated that rather than pattern recognition it should be called data interpretation. o D. Gross agreed that the term pattern recognition should be avoided o The Chair agreed
• Chair stated 60270 and 60076-3 will be provided to the members and Erin agreed this could be done.
• B. Larzelere noted that as a member of the ANSI TAG you have access to these documents and others and the cost was only a few hundred dollars
• The Chair compared C57.124 to C57.113 o C57.124 needs major revision o C57.12.01 already provides procedure o Some parts of C57.113 could be referenced
• Chair showed the dielectric test table from C57.12.01 noting that PD was a routine test for cast coil but optional for resin encapsulated
• The Chair noted that there are eight different connections shown in C57.124 and questioned if all were needed, but he needs input from the dry-type manufacturers and request that these be carefully evaluated when reviewing the document.
• H. Shertukde commented that the Navy and Army are requesting PD during impulse test and proposed adding a circuit for this test.
o Chair does not feel scope includes type of test since it is not specifically wide band o D. Gross agreed that this document is not suitable for that test and that pc is not the
correct measurement. o Chair suggested that this could be provided as an informative annex and he requested H.
Shertukde to provide wording which he agreed to do. • The Chair noted again that this was the first meeting but the members need to determine the
content and more discussion is warranted after reviewing the document before the next meeting. • Chair said the PAR has not yet been submitted but he will submit it soon and an approved PAR is
expected by the next meeting. • There was no new business • No new business • Meeting adjourned at 9:10 AM

• Meeting came to order at 11:02 AM 10/24/16. • Started attendance sheet around the room. • Chair reviewed the new patent statement - no patent issues. • Only 8 members present out of 26 hence there was no quorum. • Total participants were 24 (16 guests). • Chair mentioned that this will probably be the last meeting before balloting starts. • Last meeting minutes could not be approved due to lack of quorum. • Chair showed the previous minutes on the screen for attendees to review - no
comments. • Previous comments from Atlanta were shown on the screen - no additional comments. • Chair asked for comments on the title shown in the PAR document - no initial
comments. • Robert Ballard (Casey) asked if we were going to ask for a PAR amendment, chair said
yes. Casey also asked if there is intention to ask for extension. Chair clarified there is no intent.
• Casey requested that we review PAR requirements for the group to see - discussion followed.
• We reviewed the new title - chair clarified voltages for several guests. • Blake Cooke pointed out the word safety still remained in the scope - chair addressed
the issue. • The statement "recommended practice" was also reviewed, chair addressed same. • Casey asked about combining C57.12.50 and C57.12.51 - he said the subcommittee
approved this previously. • Chair pulled up the Atlanta minutes - he confirmed that the group agreed to combine
C57.12.50 and C57.12.51. • Chair pointed out that we were trying to get the PAR submitted and to focus on that
effort in this meeting. • The group agreed with the chair that the "heavy lifting" on the document is done - it is
nearly ready. • Casey reviewed C57.12.50 scope and purpose - discussion followed. • More discussion surrounding kVA - chair mediated discussion between Robert
Thompson(Bob), Diru Patel (Dhiru), Casey and others. • Suggestion made to remove low voltage 208Y/120 - 4160Y inclusive - discussion
followed. • Diru asked that "500kVA and smaller" along with the last sentence in the scope be
removed. • Discussion regarding consistency with C57.12.01 - Casey quoted purpose and scope for
the group, we reviewed both and insured that every type of transformer was now included.
• The group reviewed the scope one final time and agreed it was ok.
Annex D
Page 12 of 14
• In the purpose the group agreed to change to 5KV class low voltage and 1.2KV class to 36KV class.
• Chair changed scope, purpose and title to include ventilated transformers. • Casey reiterated proper steps for a PAR - PAR must also go through the WG. • Casey asked "do we need to have a PURPOSE in this document, it seems redundant". • The group voted unanimously to simply remove the PURPOSE. • A bit more discussion on submitting the PAR.
The final version of title and scope is provided below, this will circulated among members for approval.
Title Guide for mechanical interchangeability of ventilated dry type transformers Scope This standard sets forth characteristics of ventilated dry type transformers relating to
performance, limited electrical and mechanical interchangeability, as well as recommended practice for installation of the equipment described, and to assist in the proper selection of such equipment. Specific rating combinations are described up to base of 7500 kVA, high-voltage class from 1.2 kV to 36 kV inclusive, and low-voltage class up to 5 kV. This standard does not apply to other types of transformers such as specialty, sealed dry-type, pad-mounted dry-type, instrument, step and induction voltage regulators, arc-furnace, mining, testing, welding, and rectifier transformers.
The meeting adjourned at 12:15.

D.5.1 UL/IEC MVDT Thermal aging - Roger Wicks provided update regarding Future IEC 61857-41 New Work Proposal,
a test procedure for the thermal evaluation of an electrical insulation system, for use in dry-type, cast-coil and resin encapsulated transformers operating at voltages of l kV and above. This review was part of the C57.12.60 meeting minutes that was delayed to the end of the SC meeting due to expected length of discussion.
- Roger pointed out that although he is Chair of IEC TC 112, the technical committee this standard would fall under, he was not made aware that this new work proposal would be submitted prior to it being entered this past summer.
- Roger said that this NWP was discussed at length at recent TC 112 meeting held in Frankfurt, and that is was agreed that both TC 112 (Systems) and TC 14 (Transformers) would work together in the development of this procedure, taking into account work being conducted in IEEE C57.12.60 WG.
- Ken McKinney (UL) confirmed that UL will certify to IEEE C57 transformer standards, which now only references use of MV electrical insulation systems approved per IEEE C57.12.60. Ken said, however, that UL is interested in working with both IEEE and IEC and will continue to do so.
- Roger pointed out that current C57.12.60 may not be written a way that it can be easily followed by those who do not routinely run tests described in the standard, and that better examples and clarification may be needed.
- Roger felt that there was merit to the test procedure described in the Future IEC 61857-41 document, and it may be useful as a screening test or a method to approve new minor insulations inside of 12.60.
There was some discussion regarding the relationship between IEEE and IEC, as this was brought up during October 3, 2016 UL Round Table discussion regarding the new IEC 61857-41 test procedure. At the meeting it was described that IEEE would no longer be interested in cooperating with IEC. Casey Ballard had reviewed this with Erin Spiewak (IEEE) and presented the following summary of his discussion. - IEEE will continue to cooperate and work with IEC in the effort of standards
development. This is demonstrated by recent promotion of Erin Spiewak to new IEEE role, where part of her responsibility will to investigate how IEEE and IEC can work better together.
- Confirmed that IEC / IEEE duel logo projects will continue. - Described that IEEE has decided not to engage as member of (future) US TAG’s, but
will continue to maintain participation in current TAG’s. The decision to not participate in future US TAG’s is in support of IEEE desire to expand relevance outside of US, and participation in US TAG (only) did not support this goal.
- Rick Marek described that IEC and IEEE standards do not always align. Rick asked that the IEC 60076-11 CDV (Dry-type Transformer) be circulated to members of the IEEE Dry-type SC to help show differences between it and corresponding IEEE documents.

E.1 Introduction / Attendance
Introductions were made and the attendance list circulated.
There were 14 members and 24 guests present. One guest requested membership,
The total membership of the SC is 17. We needed at least a total of 9 members to be present in order to have a quorum. This was achieved.
The agenda for this meeting was approved after a motion by Eric Davis, which was seconded by Paul Jarman. As an addition to the agenda, a presentation on Medium Voltage Direct Current (MVDC) Series Resonant Converters was added.
E.2 Approval of the minutes of the March 21, 2016 meeting in Atlanta
The minutes from the Atlanta meeting (Spring 2016) were approved after a motion by Pierre Riffon, which was seconded by Klaus Pointner.
E.3 Brief report on the meeting of the Administrative SC
Clarification was made that a task force should develop the scope and purpose for a PAR and obtain a PAR before a working group is created and working group officers are appointed.
It was confirmed that a quorum is defined as having 50% or more members in attendance. (Not 50% plus one).
The word “safety” should be avoided in standards. We should e.g. use “recommended” instead.
A WG chair must always ask the members if they are aware of any essential patent claims that could affect the work by the WG. That should then be brought to the knowledge of all WG members and to the minutes of the meeting. The following suggested wording was provided, “If any individual believes that patent claims might be essential patent claims that fact should be made known to the entire working group and duly recorded in the minutes of the working group meeting” This is only required for working groups and not task forces, ad hocs etc.
Steve Antoz will be heading a task force to clarify the qualification requirements, benefits and duration of Emeritus Member classification.
There will be a 100th anniversary celebration at the spring 2018 meeting in Pittsburg. Please let Greg Anderson know if you would like to help with planning.
The minutes from the sub committees must be submitted before December 4th 2016.

- Number of comments: 7 2 technical, 3 editorial and 2 general
- Paul Jarman pointed out that it is possible that editorial comments will come after the IEC general meeting in Frankfurt, October 2016.
- Decision by Standardization Management Board (SMB) SMB agreed that standards with many alternative requirements were an unsatisfactory response to the objectives of international standardization. This affects the possibility to publish the dual logo standard for HVDC transformers. It affects also the other dual logo standards. This decision will be reviewed by SMB in February 2017.
• There has not been any meeting, with the joint WG, since (prior to) the Atlanta meeting. Mats Berglund, Anders Lindroth (former IEC chair) and Ulf Radbrandt met October 19th to propose actions to the comments from the Ballot (IEEE) and CDV (IEC). The comments and the proposed actions have been circulated within the joint WG for comments.
• Summary of the proposed actions (IEC and IEEE combined):
- Totally 52 comments
- 6 technical comments
- 1 must be satisfied 1 rejected
- 5 don’t have to be satisfied 5 agreed
- 34 editorial comments
- 3 must be satisfied 3 agreed
- 31 don’t have to be satisfied 28 agreed, 1 partly agreed, 2 rejected
- 12 general comments
- 6 must be satisfied 5 agreed, 1 partly agreed
- 6 don’t have to be satisfied 1 agreed, 1 agreed/open (more info needed) 1 partly agreed, 3 rejected
• The most critical comments and the actions were shown and discussed. The discussion were as follows:
- It is too late to change the scope (regarding Line Current Commutated (LCC) technology or Voltage Source Converters (VSC) technology). This standard covers all HVDC transformers including VSC where applicable.
- A comment to put safety aspects in caution boxes was partly agreed. This was related to remaining charge after DC voltage tests. The word “safety” was proposed to be removed from the wording “Appropriate safety precautions should be taken”. The reason was that the use of "safety precautions" in the document does not refer to personnel safety or damage of equipment but rather to consequences for the test result.
Annex E
Page 4 of 5
During the discussion regarding this, it was pointed out that it still can be a safety issue for testing personnel since there can be remaining voltage at terminals and that could lead to electric shock if touched. Maybe we should add caution boxes about caution to avoid electric shock. This will go back to the joint WG for review.
- A comment to include a reference to the report detailing various gasket materials by the Canadian Electrical Association (CEA) was proposed. It was agreed to include this if we can find that report. The report is mentioned in Annex C (Design review). The SC members are encouraged to search for that report and (if found) send an e-mail with the document number and title to Mike Sharp and Ulf Radbrandt. If the report is not found then the sentence “The Canadian Electrical Association (CEA) has produced a report detailing various gasket materials as compared to each other.” will be removed.
- Comments to add captions to the table and to the figure in the Annex was rejected. That might also be requested by the IEC editorial review. In that case we can add the captions.
• Planned coming work with this document
- Decide on action regarding the Canadian Electrical Association (CEA) report (detailing various gasket materials).
- Wait for the final decision by the Standardization Management Board (SMB), if we can have the dual references (IEC or IEEE).
- Based on the SMB decision, decide if we should continue with the dual logo standard or make two separate but identical standards where the alternative references are removed. E.g. if the document states today “according to IEC 60076-1 or IEEE C57.12.90”, then “to IEC 60076-1” will be removed from the IEEE standard and vice versa.
- Recirculation ballot within IEEE.
- FDIS within IEC. This might not be necessary due to the 100% approval rate.
E.5 Old Business
E.5.1 Revision of IEEE Std 1277
The task force chair, Klaus Pointner, presented the draft PAR for revision of IEEE 1277.
• The proposed title is “Standard General Requirements and Test Code for Dry-Type and Oil-Immersed Smoothing Reactors and for Dry-Type Converter Reactors for DC Power Transmission”.
• The standard should also cover dry-type converter reactors for voltage source converters (VSC).
• A discussion followed regarding if the standard should cover converter reactors for all topologies or VSC converters.
- A conclusion was that the standard should cover converter reactors that are in series with the semiconductor valves where the reactors see both DC current (a third of the DC current at the DC side) and AC current (half of the AC current at the AC line). The stresses of those reactors are quite similar to stresses of smoothing reactors.
Annex E
Page 5 of 5
- Another conclusion was that the standard should not cover converter reactors e.g. for 2 or 3 level converters when those reactors are in series with the AC line where the reactors don’t see DC currents.
- The final conclusion of this discussion was to include in the standard only those converter reactors that carry some DC current. It was also agreed that this should be included in the scope.
• There was also a discussion if the standard should cover oil immersed converter reactors. The conclusion was not to include these as it is too early. No one was aware of their application in service.
• The present standard does not include a “Purpose” but it includes a “Need”. The “Need” should be transformed to a “Purpose” in the revised standard.
• The draft PAR will be circulated within the SC.
• The SC should agree about the title, scope and purpose of the standard and the PAR should be updated.
• We should have a definition of converter reactors for Statcoms (SVC),
• If the PAR is approved then we should try to arrange a first WG meeting in the next committee meeting (Spring 2017). That WG meeting should then precede the SC meeting. A discussion followed regarding if we could handle the revision of this standard directly in the SC (as we did for the last revision). In that case, no separate WG meetings would be needed. The decision was to perform the work in the SC after a motion by Christoph Plötner, which was seconded by Klaus Pointner.
• The present standard is in a good shape and most work will be regarding converter reactors.
• We should also follow, and perhaps harmonize the work with, the revision of IEC 60076-6 (Power transformers – Part 6: Reactors). That IEC standard covers smoothing reactors today and might cover converter reactors later.
E.6 New Business Les Recksiedler made a presentation regarding work with Medium Voltage Direct Current (MVDC) Series Resonant Converters with voltages up to 100kV. A Cigré - WG (C6.31 Medium Voltage Direct Current (MVDC) Grid Feasibility Study) is started. The converters are e.g. intended for feeding remote villages and for military applications (e.g. marine) The converters should be small, compact and modular. They should also be of Plug and Play function. The conclusion, following a discussion, was that the transformers (for this applications) probably should be covered by the converter transformer standard (IEEE 60076-57-129) in the future but that it is too early to include them now.

F.6.3 WG PD in Bushings & PTs/CTs PC57.160 - Thang Hochanh
Attendees: 57 Members attending: 20/34 Rosters: Circulated for members and guests. Agenda: An agenda was presented for the meeting. Essential Patent Claims: Text was displayed and the Chair inquired as to if anyone knew of essential patent claims. None were brought up during the meeting. Minutes: Motion approved David Wallace (1st) & Pierre Riffon (2nd) Items discussed based upon comments received: A total of 17 comments were received for discussion many were editorial or minor in nature. Details of the discussion points are below. Comments accepted and which will be in the next draft:
• Introduction – An introduction will be added to the draft.
• IEEE C57.13 was not in the list of references.
• 6.3.1 Figure 3 text is to be updated for consistency of wording which references test taps.
• 6.3.2.1 Pierre Riffon proposed text for the bushing section to match the instrument transformer section regarding measured PD limits after the calibration step.
• 6.4 It was proposed to move the list of abbreviations from 6.4 up in the document to 3.2 as they are used throughout the document.
• 6.4 Shibao Zhang proposed an editorial change from ‘is’ to ‘are’ to correct grammar.
• 6.4 Shibao Zhang proposed an editorial change in paragraph 1 to change the indication of bushing tap for consistency.
Annex F
Unrestricted Page 3 of 6
• 6.5.1 Shibao Zhang proposed to add the following text to the end of the section. "Calibration circuits in Figures 10 and 11 may be slightly adjusted to reflect the testing circuits in Figures 5, 6, and 9. However, the calibration injection points should always be the outlet of the capacitance C1 of the test object, points A and B. “
• 6.6.1 Pierre Riffon indicated that a precision need to be mentioned to reflect the point that the verification of a valid calibration is performed at a level not necessarily at 50% of the partial discharge limit for DC bushings.
• Thomas Sizemore indicated that several figures need to be updated to improve consistency of line weights, etc.
• Pierre Riffon: Correction to figure 17 labeled as a balanced circuit (unbalanced circuit).
• Figure 10: For the clarity of the figure, the chair proposes a dotted line box around the capacitor and the square wave signal generator.
• 7.2.1 Vladimir Khalin indicated that no explicit instructions were provided for the testing of line to line VTs.
• The annex 'PD Measuring Circuits' covers many of the same topics as the guide. It was decided to remove it due to duplication of definitions and explanations.
• Thomas Sizemore propose an introduction to be added to the annex related to PD patterns.
The follow comments were discussed but not accepted.
• 6.5.1 Jitendra Mamtora indicated a potential error in the calibrator circuits used in the guide.
• An additional pattern taken from an online monitoring system was discussed. The PD pattern cannot be positively identified being in the bushing installed on a transformer.
Additional items discussed: The wording of the PAR was discussed. It currently does not cover DC bushings which are in the draft document. The working group agreed to pursue a change in the PAR to incorporate DC bushings in the guide. Tom Provost indicated that he is willing to assist the Chair in this process. Motion to adjourn: A motion was presented by David Wallace and was seconded by Detlev Gross. Spring meeting 2017: The chair plans to wrap-up the draft for the New Orleans meeting and submit the Draft for approval by the WG.
F.6.4 Working Group on Revision of C57.13.5 "Standard of Performance and

This was the second WG meeting.
Attendance has been recorded in the AM system.
Required quorum was met, presence of at least 7 members was required.
Revision 2 of agenda has been reviewed and a motion to approve the agenda has been made by Mr. T. Sizemore and seconded by Mr. S. Oakes. The revision 2 of the agenda was approved by all members present.
Minutes of Atlanta meeting were approved unanimously. The motion was made by Igor Ziger and seconded by Thomas Sizemore.
Call for patents has been made and no essential patent claims have been reported.
As the first item of business, the Chair proposed a new relaying accuracy designation when an anti-remanence gap is added within magnetic circuits. The proposal was to add a "R" suffix after the C class designation as it is done in IEC 61869-2. After discussion, a motion made by Zoltan Roman and seconded by Igor Ziger to survey if this rating is really needed. The motion was accepted by 12 members, one abstained. The chair will initiate a survey in this respect within the Instrument Transformers Subcommittee membership prior to the next meeting. The Chair will also ask if this class is better to be added, for the time being, to C57.13 (amendment) or to C57.13.5.
Draft 1.2 of the revision of C57.13.5 was circulated by Email to the members and guests prior to the meeting on September 11, 2016.
Changes proposed in D1.2 have been reviewed one by one up from clauses 10.9.2 to A.2, Several changes were mainly editorial in nature such as reference clause numbers and date of referenced standards.
Among the proposed major technical changes, the following items have been discussed:
• Only external visual inspection will be required after short-time current test;
• The choice of fuse wire dimension and material for arc initiation during internal arc test will be let to manufacturer. The only criteria is that the fuse wire shall melt within 30 electrical degrees after current initiation;
• Alternative gases will be allowed and suggested for the internal arc test. The Chair will make a proposal prior to the next meeting;
• Additional details have been added regarding the documentation to be supplied to the test laboratory for test sample identification;
• The temperature rise test procedure for CTs having dielectric losses greater than 20% of the RI2 losses has been discussed but we were running of time. Zoltan Roman will make a proposal for the next meeting in New Orleans, LA.
Clauses A.2 and beyond will be reviewed during the next meeting in New Orleans.
The meeting adjourned at 10:45 am on October 25, 2016. The adjournment motion was made by Mr. T. Sizemore and was seconded by Mr. R. Ogajanov. The motion was approved unanimously.

F.6.5 C57.13.9 Task Force for PLC Capacitors and CCVT’s – Zoltan Roman
The Task Force held its second meeting at 11:00 AM.
A total of 31 people were in attendance, down from 41 at the previous meeting. 14 of the 21 members were present. 1 additional person requested membership.
After introductions the minutes of the previous meeting and the agenda for this meeting were presented and approved.
The draft PAR has been reviewed. It will be submitted as-is with the exception of the date of the draft submittal for the ballot. It has been reiterated that one of the objectives is to harmonize the new standard with the existing C57.13, C57.13.5 IEEE standards, as well with the current IEC and CSA CCVT standards.
The existing CCVT standard, ANSI C93.1, has been reviewed and the chair pointed out the need for restructuring. Rather than modifying this document the preference is to start from scratch using the IEEE template. There were no objections to this approach.
The chair presented a table with the proposed structure and a schedule for development of the new standard. The plan is to complete the standard in 7 meetings and some teleconferences in between. There were no objections.
The TF reviewed and compared the voltage ratings and dielectric test requirements between C93.1, C57.13, C57.13.5, CSA and IEC. It was noted that the test levels in C93.1 were in some cases much higher than in the IEEE or IEC requirements and it was suggested that they should be the same as for other instrument transformers. This was questioned by S. Misur, stating that there may have been a good reason for this so we should be careful. However, nobody in attendance knew the reasons for the higher levels. D. Sharma offered to provide a switchgear standard as another reference.
The chair offered to prepare a table summarizing the dielectric test requirements for the next meeting and make initial proposals for levels to include in the draft, which will be discussed and voted on in the next meeting.
The meeting was adjourned shortly before 12:15 PM.
The next meeting will be at the Spring 2017 Transformers Committee meeting in New Orleans, LA, between April 2 and 6, 2017
F.7 Special Presentation
Zoltan Roman presented the results of several CTs measured and plotted in both the current parallelogram and the proposed square for accuracy classes. Eddy So gave a presentation regarding the applicability of TCF/RCF in current applications. Some questions were raised concerning how utilities and other groups such as Measurement Canada would adapt to the proposed changes.

Old Business
a. C57.12.00 Revision – Unresolved Ballot Comments forwarded to the SCIF as follows:
Balloted document: Page 32, 6.6.1, line 13; Standard needs to maintain the sentence "There are other insulating fluids that may be suitable and are commercially available..." from previous version; nowadays, there are other liquids as synthetic esters that are commercially available.
This was rejected as out of scope but could be considered in the future. It was noted that at the time of the revision, neither ASTM specifications nor IEEE Guides for use of other alternative insulating liquids for use in transformers existed.
b. This issue remains unresolved and needs review and consideration by Insulating Fluids/Working Group. If this suggestion has merit, consider making a suggestion to WG C57.12.00. The Chair assigned Patrick McShane to study the issue and make a recommendation of the next meeting.
G.2 New Business
a. C57.12Fredi Jacob stated that he believes while C57.155 DGA of Esters covers many needed aspects, there is more information needed regarding gas evolution vs. the severity of faults.
b. A question was raised by a user that they are considering gas insulated transformers and wondered if the SCIF has considered working on a guide for insulating gases. The Chair said up to this point there has been no demand but would make some preliminary investigation on the issue

Document Status
Claude indicated that a draft 3 has been sent out for review. He asked the WG for feedback on whether we are moving in the right direction. A straw ballot will need to be sent out by early next year to be able to move forward.
Claude Beuchemin presented a short history of the guide and how that has led to where we are today. For more details, see the presentation and the draft attached at the end of the minutes.
Claude asked if anyone knew the source of the 90% Norms (No hand were raised!). It originated in the early (1972) CEGB (Central Electricity Generating Board, UK) use of DGA.
The first revision occurred in 1991. The analysis and sampling sections were removed and transferred to ASTM. The Halstead graph was introduced. TDCG was introduced. Key gas graphs and Table 1 were also introduced. Numbers for table 1 were carried from the 1978 version with the addition of two higher value sets, probably from the same source. Four conditions describing the transformer status were added.
Use of the 1991 guide with the selected limits resulted in a large amount of false positives, due principally to the too low limits for CO and CO2. In the early 2000s, an important revision process was undertaken and generated a large amount of new text, but the guide expired in 2005 before that work could be completed.
The guide was re-installed "as is" with minor corrections in 2006 (The actual version. labelled 2008)
Work was immediately started on collection of data to improve the values in the tables, as well as continuing the work for general improvement of the guide. A study presented during a IEEE meeting at that time indicated that approximately half of the DGA were above condition 1 (Caution) and a third were above condition 2 (Warning).
The result of this revision work was presented at this meeting. A draft (3.0) was sent to all the WG members and guests at the beginning of October for comment and review.
Annex G
8 of 14
The draft guide contains 6 main sections, 9 annexes, 4 tables, and a new flowchart and figures.
A short presentation of the content of each sections and annexes was made.
It is to be noted that the 4 tables in the draft do not contain numbers. The reason is that the TF on data analysis has yet to complete the work. It is to be done before the Straw ballot is issued.
The work remaining to be done was presented as follows:
- Complete text with comments
- Update bibliography with WG suggestions
- Decide if we add recommendation to use on-line monitor on gassing transformer
- Decide if we maintain sampling section
- Finish data analysis and select norms
- Straw ballot
- Ballot
- Ballot resolution
- Prepare a tutorial
- Write a white paper on the data analysis
The floor was open for discussion
Tom Prevost made a motion that the Annex on Sampling be removed and was seconded by Jim Dukarm. Tom indicated that this is more of a guide for interpretation and ASTM is more of a guide for taking the samples and the analysis.
Valery Davydov commented on a presentation he gave in the moisture in insulation WG. From this, the location that the oil sample is taken was found to be very important. Claude commented that this is not exactly what is presently being discussed.
Rainer Frotcher – Indicated that the new guide is much improved and a tremendous amount of work has been done.
Brian Sparling indicated that the guide is meant to be used worldwide, while the ASTM guides are not. He indicated that he refers people to the ASTM document but it is not well known outside of the US and they may not have access to those documents.
Tom Prevost indicated he understood where Brian is coming from, but that if we followed this line of thought in all of our standards and guides, they would be very long. He expressed concerns that by having the information in this guide, then there is a risk
A call for vote was made. There was 1 abstention, 3 negatives, and 43 in favor of the motion. The motion passed.
Annex G
9 of 14
Claude reviewed the remaining work to be done.
• Complete text with comments needs to be reviewed. • Update bibliography with WG suggestions • Decide if we add recommendation to use on line monitor on gassing
transformers.
Claude asked if there was a motion to recommend the use of on-line monitors. No motion was made. Clair Claiborne indicated that there are other documents that adequately cover on-line monitoring and did not feel a need to include this in C57.104.
Fredi Jakob indicated a concern with the figure in Section 4. The figure shows a rapid drop in H2 concentration at low temperatures, followed by a gradual rise with increasing temperature, which is misleading. H2 generation caused in abundance by partial discharge occurs independent of temperature, and in fact can occur at low temperatures (i.e. normal operating temperatures). This causes the peak in H2 generation shown at low temperatures in the figure, which is an electrical phenomenon and not a thermal one.
Michel Duval explained the background of the figure. Claude indicated that maybe the temperatures could be removed if that is causing concern with the figure. More discussion will be needed on this topic.
Juan Castellanos – Asked if we are planning to segregate the data by type of transformer. Claude indicated that there is not enough information in the database to support this.
Claude closed by requesting that the WG members provide their comments within the next couple of weeks if not sooner.
The meeting was adjourned at 6:00PM

o Still awaiting input from 5 BRC members in order to finalize Draft 4 for recirculation
• New Business: Discussion of Ballot Comments of special interests:
o Essential Patent Claims LoA: Negative vote received due to lack of LoA. Susan McNelly said the discussion is out of the hands of the WG, to be addressed by IEEE SA during their approval process.
o “Allowable free breathing exposure: Statement in draft that would take 5 7 years exposure before free breathing could become a practical issue was challenged, stating a lack of references. Alan Sbravati discussed test and field case history results of service aged ester fluid exposed to atmosphere for a long period. A technical paper presented by Alan will be made available to the BRC.
Annex G
Page 11 of 14
o Comment requesting the addition of corrosive sulfur to acceptance value Table 2. Discussion included that NEs naturally lack content of corrosive sulfur. Some supported inclusion due to possible contamination.
o Several comments requested validation and expansion of values in the service aged NE limits. A task force comprising Luis Cheim, Claude Beauchemin, Scott Reed, Alan Sbravati, and John Luksich was formed to analyze data on service aged fluids received from three laboratories. Luis and Claude both stated due to the huge data base, an analysis could not be completed for many months, maybe over a year. A motion by Dave Wallach to defer analysis of the service aged fluids to the consolidated fluids guide task force was passed. The data analysis will not be done within this working group. If the TF on Consolidation agrees, the gentlemen list above agreed to volunteer. The Chair stated that with this decision, the next recirculation balloting could occur even before end of this year.
o There was discussion of allowable fluid temperature limit should be for vacuum processing. Concerns included loss of inhibitors and boiling of NE at the current temperature limit in the draft.
o There was discussion of whether or not corrosiveness values for ester fluid should be established.
o There was discussion on issue of some Medium/Large OEMs that use vapor dryout, fill with MO, test with MO, and then field fill with NE. There seemed to be a consensus that factory testing with the NE. .
• The meeting adjourned by acclimation at 3:30 pm.
Respectively submitted, Jim Graham, Secretary Chair Post Meeting Notes: The need for the WG to meet in S17 is probably very low. When Draft 4 is finalized by the BRC, it will be sent to the WG members for review, prior to submittal to IEEE SA recirculation vote. Nick Perjanik was inadvertently left of the list, but he is also a member of the BRC. Action: Summarize issue of Lab data analysis and forward names of volunteers to TF Consolidation Chair Tom Prevost.

A motion to approve the Spring 2016 Agenda was made Jim Graham . Patrick McShane seconded the motion. There were no objections to the approval of the Agenda. Next, a motion was made by David Sundin and seconded by Mario Lacarno to approve the Spring 2016 Atlanta meeting minutes. There were no objections to the approval of the minutes. Chairman Tom posted the Patent Claim. No notifications or comments were received. Chair’s Remarks: As a review of the current document status:
-Patrick McShane announced that C57.147 will have the Par extended to 2018 because there were 220 comments to the last ballot.
A presentation was given by Chairman Tom Prevost to discuss the Scope, Title and Purpose and he referenced the Scopes of C57.106 and C57.147. In response, Rainer Frotscher gave a presentation suggesting to separate this guide into two separate guides—one for less flammable and one for flammable insulating fluids. Three options were proposed by the chair on what the Scope of this WG should be: Option A. Create a Mineral Oil Guide and Guide for all other Insulating Fluids. Option B. Create a Guide that includes all Insulating Fluids for Equipment with the exception Load Tap Changers. Option C. Create a Guide that includes all Insulating Fluids and includes Load Tap Changers. A motion was made for Option C by David Sundin and seconded by Luiz Cheim. The motion carried. Next, it was discussed which equipment should be included as part of this Scope. A motion was made that this Scope should be for Transformers, LTC, Regulators and Reactors by Mark Perkins and seconded by Jim Graham. The motion carried. Finally, after discussion whether to include Bushings as part of this Scope, Jim Graham made a motion to exclude Bushings as part of Option C. Rich Simonelli seconded the motion and the motion carried. The chairmen summarized the discussion of the scope as follows. Only the applicable equipment has been agreed to so far: This guide applies to insulating liquids used in transformers, tap changers, regulators and reactors. Agree 10-24-16 The guide discusses the following:
• Analytical tests and their significance for the evaluation of mineral insulating oil. • The evaluation of new, unused mineral insulating oil before and after filling into equipment.
Annex G
Page 14 of 14
• Methods of handling and storage of mineral insulating oil. • The evaluation of service-aged mineral insulating oil. • Health and environmental care procedures for mineral insulating oil.
The characteristics of the liquids discussed in this guide do not include liquids that is in factory fill lines, nor does this guide cover reclaimed oil installed in new equipment. The qualities of such oil, if used, should be agreed upon by the manufacturer and the user of the equipment. The next meeting we will discuss the remaining bullet points in the scope and more specifically the following bullet:
• The evaluation of new, unused mineral insulating oil before and after filling into equipment. No New Business was discussed and the meeting was adjourned at 10:47 am.

Task Force 9 – Field application of knowledge on moisture * Note: This section lists the risks associated with moisture Task Force leader – Jim Thompson The chair presented TF chair Thompson’s summary of progress to date;
“I am reviewing papers and guides on moisture risks including bubble evolution in oil, dielectric failure, and premature aging of paper. I authored the Cold Start VDE response curve in the C57.106-2015 Annex and can provide more details. Other guides already have bubble evolution risk information. I will search the IEEE Explore site for aging vs moisture in paper/oil systems. I hope to have a draft in two weeks. I still don’t have e current C57.91 but will get a new C57 series CD after this meeting. Most of the text regarding risks will be discussion and references to C57 guides. I will also add a bibliography.”
It was suggested that this document must include moisture levels associated with known risks. The chair commented that this should be included in the work of TF 9. Rough Draft of this section to be completed by end of January 2017. Task Force 10 –Moisture Migration, Distribution and Moisture Equilibrium Charts Task Force leader – Bruce Forsyth The task force received additional volunteers since last meeting and a scope has been developed. TF 10 Scope:
This chapter presents the best known information related to a) Moisture migration in insulation systems; b) How moisture distributes throughout an insulation system; c) Moisture equilibrium charts applicable to transformer insulation systems.
The initial focus will be on liquid-filled insulation systems, but an effort will be made to provide similar information for gas-filled insulation systems. Oleg Roizman commented that basic adsorption isotherm curves for cellulose were developed in 1960 and came from the textile industry. He asked a question on whether or not to use these existing “Jeffries” curves or create new ones. The chair commented that the development of new adsorption curves, although preferred, may take too long for inclusion in this document. (Task force is looking for input from material suppliers) A draft as was asked to be completed by the end of Jan 2017.

H.2 Old Business
The PAR for the Proposed WG – PC57.165 “IEEE Guide for Temperature Measurements for Liquid Immersed Transformers and Reactors” has been submitted and should be considered in December. The activity chair is Phil McClure.
A study group was formed to address comments related to C57.91, “Guide for Loading Mineral Oil-Immersed Transformers and Step-Voltage Regulators” consisting of Gary Hoffman and Bruce Forsyth.
A C57.12.00 Ballot Comment was addressed. The comment concerned clause 4.3.1 and was raised by Mark Perkins; operation at high altitude also affects the cooling performance, and this should be addressed in addition to dielectrics.
• C57.12.00 clause 4.3.1 refers the reader to C57.91.
• Reviewer Response: The balloter is correct that high altitude affects cooling performance, however IEEE Std. C57.91 is cited in Clause 4.3.1. In IEEE Std. C57.91-2010, the normative Annex E, titled "Unusual temperature and altitude conditions" the text of sub-clause E.2 specifically addresses the balloter's concern as follows: "The effect of the decreased air density due to high altitude is to increase the temperature rise of transformers since they are dependent upon air for the dissipation of heat losses." Hence it is the judgment of the reviewers that no change is required to C57.12.00-2015 to address this concern as it is referenced in Clause 4.3.1 of IEEE Std. C57.12.00-2015 by referencing IEEE Std. C57.91 and IEEE Std. C57.91-2010 adequately explaining the consideration of air density on air circulation as noted above.

H.3 New Business Jeff Ray expressed a concern about the temperature rise test procedure found in C57.12.90-2010 Section 11.2.2 Hot-Resistance Method. He has noted variations in the way that these tests are performed among various manufacturers and plants. He spoke in favor of a task force to survey owners and manufacturers to determine the current methods and expectations from all sides. The survey information would be published without identifying the individual responses from each party. Mr. Ray then made a formal motion to produce and publish such a survey. The motion was seconded by Matt Weisensee. Stephen Antosz noted that a 2015 version of this standard has been published and there were changes to the subject section. The chair asked Mr. Antosz about the workability of a confidential survey and Mr. Antosz said that it could be done. Gary Hoffman stated that the standard is clear and that the owners should ensure that it is followed. Mr. Antosz suggested that Mr. Ray may want to perform a review of the standard instead of a survey. The motion failed with a vote of 2 for and 57 against. Stephen Antosz introduced Jianbin Fan, representing the Chinese Society of Electrical Engineers. Mr. Fan provided a presentation regarding a CSEE standard for lead exits, 1000 volts and above. Mr. Fan said that the standard had been presented to IEEE for adoption. It was initially rejected, but Mr. Fan was eventually referred to the Insulation Life Subcommittee for further consideration. Mr. Gary Hoffman spoke warmly in support of working together in global initiatives. Sajib Som noted that the CSEE standard directly specifies means and methods in a way that will block development and hamper introduction of new ideas. Mr. Som suggested that the document could potentially be considered a guide, but not a standard. Tom Prevost stated that the document does not fit the scope of the ILS. He stated that the document may be more appropriate for ASTM rather than IEEE. Don Platts stated that the document fits the TC scope, but perhaps not the ILS. Mr. Platts said that IEEE standards are focused on focused on functionality but the CSEE document is focused on means and methods. Mr. Hoffman countered that construction methods were in the purview of the TS, but agreed that the ILS may not be the correct subcommittee. Mr. Fan responded to each of the comments and said that he thought that the document would be appropriate for the IEEE. The Chair thanked Mr. Fan for his presentation and agreed to consult the TC leadership for guidance on how to proceed. Shamaun Hakim raised an issue about testing in C57.12.90. Jeff Ray, Chair of the C57.12.90 Task Force, said that he would like to study the issue further and report at the next meeting. Based upon issues raised in the Working Group meeting for the revision of IEEE Std 1276, the chair asked for formation of a Task Force to perform a procedural evaluation C57.154, Annex B, clause B.5 and provide a recommendation regarding this data. Unfortunately, there was not enough time to organize this work during the meeting. Mr. Patrick McShane desired to make comment about the work of the Working Group for P1276. However, he could not be heard due to a lack of time. The chair requested that Mr. McShane provide his comments in writing.

H.4 Adjournment The meeting was adjourned at 9:15AM.
H.5 Post Meeting Notes Following the meeting, A task force titled “C57.154 Annex B Clause B.5 Recommendation” was formed. Robert Thompson has volunteered to chair the group, and it will meet during the next Transformers Committee meeting in New Orleans. The group was organized as follows:
Scope: This TF is tasked to evaluate the content of C57.154 Annex B, Temperature Limits and to specifically recommend the disposition of Clause B.5 to the Insulation Life Subcommittee. The TF is not authorized to make any changes to Annex B or to take any other action. Background: C57.154 Annex B Clause B.5, titled Temperature Limits, proposes equations and alternate tables to the body of the C57.154 standard based on curves composed of historical test data, which are incorporated in the annex. A presentation was made at the WG for the revision of IEEE Std 1276 in the Fall of 2016 that presented these curves without the mineral oil comparison data points. The claim was made that this data was insufficient to define such equations and alternate tables. The presentation further recommended the removal of Clause B.5 from the annex. In consideration of this request, the Chair of the Insulation Life Subcommittee requested that a task force be formed to evaluate this request and make a recommendation to the Subcommittee. Expected Result: It is expected that a small, balanced group of 5 – 8 invited members of the Insulation Life Subcommittee would form this task force to be chaired by one of these members with no ties to the ester liquid industry. It is expected that no more than two members from different companies will represent the ester liquid industry. The rest of the members will be composed of Insulation Life Subcommittee members who are relatively unrelated to the ester liquid industry. The Chair of C57.154 will serve in an advisory capacity with no vote.
Mr. McShane was recognized by the chair during the meeting, but his comments regarding issues raised at the P1276 working group meeting could not be heard due to a lack of time. Mr. McShane kindly provided his commentary following the meeting and the substance of his commentary is included here;
1. The bulk of the meeting time for working group P1276 related to the annex of C57.154. A task force should be formed to consider modifications to this annex. 2. There was discussion in the working group meeting which suggested that there is confusion about the loading guide. However, there was only one comment on this issue during the voting process for the C57.154 standard. 3. Data that is created under the methods described in previous versions of a standard should not necessarily be invalidated by newer standard revisions.

For C57.110, Rick Marek proposed a motion to take the standard to ballot. This was seconded by Sam Sharpless. The proposal was carried unanimously by voice vote.
Sheldon Kennedy stated that the C57.32 guide for neutral grounding devices received comments from ‘MS Resistance’ in France. Sheldon led a task force to review these comments and the TF agreed that changes to the recently published C57.32 are needed. Sheldon proposed a motion to the SC to form a WG to seek a PAR and make the revision to the guide. This was seconded by Tom Melle. The motion was accepted through unanimous voice vote.
For C57.105, the current chair Adam Bromley is stepping down. The Chair announced that the new chair will be Rogerio Verdolin.
Sanjib Som stated that he had a question during the Bushing Subcommittee meeting and it came out that bushing overloading capability is not as clear as it is for transformers. Hence transformer engineers need to look into this while selecting bushings for their transformers.
There was a question about the C57.12.00 system voltages and why some of the voltage variations are not +/- 5% (most are). Steve Snyder commented that this was investigated some years ago in C57.12.00 and it was established that the table reflects the North American practices.
Adjournment was proposed by Ramsis Girgis and seconded by Dan Sauer.
The meeting was adjourned at 4.15 pm.

J.8.2 Working Group on PCS Revisions to C57.12.90 - Mark Perkins
Meeting Minutes Task Force on PCS Revisions to C57.12.90
October 24, 2016, 11:00am-12:15pm Grand Ballroom CD, Sheraton Vancouver
Mark Perkins, Chairman; Craig Stiegemeier, Secretary 1. PCS Chair Comments
• Ed teNyenhuis, PCS Chair, called the meeting to order. Ed informed all that the Working Group would become a Task Force in the future. Since C57.12.90 revisions are the responsibility of the Standards Subcommittee (not PCS,) this must become a Task Force. The Task Force would still be responsible for providing PCS comments to the Standards SC for future updates to C57.12.90.
• Ed informed all that this will be Mark’s last meeting as Chair of the Task Force. The attendees thanked Mark for all his efforts to keep C57.12.90 current. Hakan Sahin will take over as the new Chair of the Task Force at the end of this task force meeting.
2. Introduction of members and guests
• Mark Perkins presided over the meeting as Chair. Craig Stiegemeier was secretary. Three (3) attendance rosters were circulated for those in attendance to record their presence and confirm their membership or guest status.
3. Attendance
• A review of the adjusted membership was conducted and 38 of the 57 TF members
were in attendance. This resulted in attendance of 66% of the membership, making
this meeting “official” as a quorum was reached. In addition, 79 guests were present
at the meeting, of which 28 were first time attendees. 20 of those guests requested
membership on the Task Force. A review of past attendance will be conducted, and
those that meet the requirement of participating in the TF and have either attended
the previous 2 meetings or 3 of the past 5 TF meetings will become TF Members.
They will be on the roster for the Spring 2017 New Orleans meeting. Also, any of the
current members will be removed if they have not attended 3 of the past 5 meetings.
Also, anyone who has not attended any of the past 10 meetings will be removed
from the rosters circulated at the Spring meeting to help control the size of the roster.

4. Agenda approval
• Dan Sauer made a motion to approve the agenda and Bertrand Poulin seconded the motion. Unanimous approval was confirmed by all in attendance.
5. Minutes of the Spring 2016 meeting
• A review of the Spring 2016 Atlanta minutes was conducted by the chair. Bertrand Poulin made a motion, and it was seconded by Dan Sauer to approve the Spring 2016 minutes as written. Minutes were approved by the membership unanimously.
6. Old Business
• A review of the discussion that occurred at the Atlanta meeting on the voltage test of the LTC.
o Test range with current at load loss connection
Rainer Frotscher from Reinhausen cleared up that the full current test is to test the tap changer. He attributed the suggestion to Joe Foldi.
Joe Foldi stepped up and explained that the intention of the test was to run through the full range of the LTC. IEC requires that the test take place for 10 times going 2 steps up and down so the reversing switch operates for 10 operations.
Pierre Riffon suggested that the test follow the IEC test. Bertrand Poulin noted that the end-to-end test is ideal. If it is not
practical, the IEC approach is a reasonable engineering compromise. His opinion is that 5 complete cycles (10 operations of the reversing switch) should be the minimum number of operations.
Ajith Varghese from SPX suggested that +2 and -2 should be operated at least 3 times. There would be
Don Ayres suggested that going from one end through the reversing switch and returning to the end, at the highest power rating of the transformer.
Joe Foldi believes that it is not unreasonable to go through the complete range of the LTC.
Shamaun Hakim of CG Power Manitoba made a comment. Jason Varnell of SPX Transformers noted that the specific type of
regulation (coarse/fine, linear, buck/boost) should be considered. Kushal Singh of ComEd noted that end to end testing is in their
specification. They’ve never had a manufacturer object to the end to end at full rated current as shown on the nameplate.
Javier Artega from ABB noted that most times LTC’s are plus/minus type with a reversing switch. He noted that linear type LTC’s do not have reversing switch and the testing should apply to all types of LTC’s.
Matt Weisensee at PacifiCorp noted that is an OEM has an obligation to test per the nameplate.
Steve Schroeder ABB South Boston is concerned that this test helps determine that a reactive type LTC is properly connected. The test makes sure that the leads are corrected properly. Steve’s opinion was that connection issues are found only with a current test, as a voltage test would not find the problem.
Mark Perkins was under the opinion that a voltage test would find the problem.
Annex J
Page 8 of 31
Jeorg Olin from SMIT Netherlands – end to end testing is a challenge with very large autotransformers. He suggests that we stick with the 2 steps up and then two down, causing operation of a reversing switch (if present.)
Mike Spurlock from AEP noted that they require an overload test at 25% above maximum nameplate rating.
Leopoldo Rodriguez of EFACEC commented that testing the LTC with full current and full voltage from end-to-end is essential in finding problems before the transformer ships. Anything less that that would not identify all issues.
The Chair summarized that the group seems split about evenly, with half preferring end to end and others preferring two steps up and down through the reversing switch
Dan Blaydon, BG&E suggested we confirm a quorum before any motions to vote. As noted above, a quorum was confirmed.
Ajith Varghese of SPX suggested that the TF vote, Rogerio Verdolin seconded. The motion was that we take a vote of end to end or +/- through the neutral.
1. 21 voted that the test be performed from end to end of the tap range; with 11 voting to go 2 steps up and then down while going through the reversing switch if present.)
2. We will include end to end in the first draft o A discussion of the current level during the test took place during the
meeting.
Krishnamurthy Vijayan of PTI Manitoba suggested the test always be
conducted at the top rating on the nameplate.
Dan Blaydon of BG&E suggested that the overload requirement be
left up to the user to specify an overload condition as they seem to
vary quite a bit from user to user.
Bertrand Poulin motioned, and Dan Sauer seconded that the test
specified in the standard be limited to the top rating of the transformer.
Dave Ostrander mentioned that the rating should be made clearer,
there may be a need for a minimum test level at 80% of the top
nameplate rating. Bertrand clarified that his intent was that the
current on the nameplate would apply for each tap. Shamaun Hakim
of CG comment that 85% was in line with the minimum heat run test
levels in our standards. Rainer Frotscher from Reinhausen suggested
that it wasn’t necessary to adjust the current for each tap as this is a
significant burden. Joe Foldi reinforced Dave Ostrander’s comment
that by putting an 80% minimum current would accomplish the goal of
performing the test with significant current without putting an undue
burden on the OEM. Javier Arteaga from ABB suggested that
changing the current at each tap would be an undue burden. The
amended motion is that the test be performed as close as possible to
the top nameplate rating, but not less than 80% of the top rating. The
motion passed with 32 member voting for the motion and no one
against the motion.
o Mark called for a discussion on the pass/fail criteria for the test.
Annex J
Page 9 of 31
Bertrand Poulin noted that a pass/fail would have to be applied to
some measurement or observation. He noted that most people go by
what they hear during the test, and observations of the current during
the transition (such as unusually high during the transition.) He noted
that DGA varies dramatically based on LTC, transformer design and
application of the LTC
Rainer Frotscher suggested that one criteria would be requiring that
DGA in the main tank should not change during the test. In tank
LTC’s should not exceed 12ppm, as some contacts will produce low
level of gasses.
Detlev Gross from Power Diagnostics suggested that DC resistance
performed before and after test should show no change. He also
noted that a requirement be placed on the compartment containing
the selector switch not produce any combustible gas during the test.
Rainer Frotscher from Reinhausen noted that vacuum switching
makes no difference based on the current of the test, but some small
amount of combustible gas may take place during selector switch
operation.
Bertrand Poulin from ABB suggested that test should be proposed,
and then voted on once the proposed text was reviewed. He
suggested the Chair should put together the material, circulate the
suggestion before the next meeting and the members come to the
meeting ready for a discussion and acceptance.
7. New Business
• As the discussion of the details of the Load Tap Changer Performance Test Procedure took the entire meeting, there was no time for new business as the time for the meeting expired.
8. Adjournment
Bertrand Poulin motioned and Dan Sauer seconded that the TF adjourn as the meeting time expired, The motion was accepted unanimously, and the meeting was adjourned at 12:17 pm.
J.8.3 Working Group for Revision of C57.109
IEEE Guide for Liquid-Immersed Transformer Through–Fault-Current Duration
Vancouver, BC, Canada, October, 24 2016
Minutes of the Working Group Meeting The meeting was held on Monday October 24, at 1.45 pm and four of the nine members were present and therefore there was not a quorum. There were a total of 35 people present which consisted of 4 members and 31 guests. Eight guests requested membership.
Annex J
Page 10 of 31
The Working group reviewed comments that were submitted by the K16 Working Group on Revisions to C37.91 IEEE Guide for Protecting Power Transformers. The first comment provided by the K16 group was to make an editorial correction to consistently refer to the “times rated winding current” instead of “times rated current.” There was no discussion on this topic and therefore the recommendation was upheld and the change will be made. The next comment was regarding inconsistencies between the values in Table 2 and the associated plot in Figure 1. Raj Ahuja added to the discussion by suggesting that the working group examine the history and source for the values that were originally in Table 2 before agreeing to change the values per the K16 recommendation. The next comment by the K16 working group was regarding the term “symmetrical currents” in section 4.0. They requested that the term be changed to “symmetrical winding currents.” There were no objections or additional discussion and therefore the working group will make the change. The next topic was regarding the term “% transformer impedance” as found on Figures 2a, 3a, and 4. They requested that the term be changed to “% transformer short-circuit impedance.” There were no objections or additional discussion and therefore the working group will make the change. The next comment from the K16 working group was an editorial comment regarding the deletion of a sentence from section 4.3. It was determined that the sentence was removed by error and will be added back to the next draft. Discussion about the changes to Table 4 were discussed in great detail. The K16 working group recommended that the old values from Table 4 remain in the guide but perhaps in a different table for historical reference. The working group decided to include the old Table 4 as an informative annex. Some additional comments were provided by the PC37.91 working group that related to the usage of the C57.109 guide but not particularly about the content of the guide. The C57.109 working group determined that the chair would respond to their comments. The topics included fault durations in excess of 2 seconds, pre-fault conditions, and single-line to ground faults. Next the working group reviewed the redline version of the D1 draft. Raj Ahuja had a comment regarding the statement in section 4.1 regarding low current values that may be the result of overloads up to 3.5 times rated current. Raj stated that the 3.5 times rated current for an overload condition exceeds that of C57.91 and should be removed. Kushal Singh commented that distribution transformers that are only protected by fuses may experience current close to 3.5 times. It was then noted that section 4.1 refers to category I transformers and therefore Raj retracted his comment. It was agreed to leave the section unchanged. A motion was raised by Bill Griesacker to adjourn. Hemchandra Shertukde seconded the motion. The working group unanimously approved the adjournment. The meeting adjourned at 2:50pm. Respectfully submitted Vinay Mehrotra WG Chair

J.8.4 TF on Audible Sound Revision to Clause 13 of C57.12.90 - R. Girgis
Unofficial Minutes of fall 2016 Meeting of TF “Audible Sound Revision to Test Code C57.12.90”, in Vancouver, BC Canada
The TF met at 1:45 PM, on Monday, October 24, 2016. Chairman Dr. Ramsis Girgis presided over the meeting. Secretary Barry Beaster assisted with the administrative duties.
After the Spring meeting, the membership had been adjusted to 52 members. For meeting preparation, a meeting agenda along with the unapproved Spring 2016 minutes were circulated to all members and guests of the last meeting. A copy of the prior meeting attendance for the past six years was circulated to the members for any possible oversight in recording attendance.
The meeting was attended by 26 of the 52 members and 65 guests for a total of 91 persons; the largest in the records for this TF. A quorum was established by a review of the meeting rosters after the end of the meeting. The proposed agenda was presented with one addition after the preliminary mailing. This additional agenda item: “Need for an IEEE Noise measurement Application Guide”, was proposed by Bertrand Poulin at the spring meeting of the TF. The revised agenda was unanimously approved without change. The spring 2016 meeting minutes had no requested changes nor corrections and was unanimously approved. Since a quorum was determined after the meeting, the agenda and prior meeting minutes were officially approved.
There were nine requests for TF membership; which will be reviewed based on previous meeting attendance.
After the introductions, Chairman Dr. Ramsis Girgis presided over the technical portion of the meeting.
The first item of business was a presentation by Dr. Chris Ploetner on the status of the IEC Sound Measurement Standard and Application Guide. Both have already been published earlier in 2016. He also presented the similarities and the small differences between the IEEE and IEC Standards. Chris commented that both IEC and IEEE Standards are widely comparable and, due to some small differences between these Standards, that the maximum difference to be expected between the Sound level measured using the two Standards is within ± 1.0 dB. He also stated that the harmonization process will continue with a target to fully align sound level measurements in the two Standards. Chris recommended to the attendees to read the IEC Application Guide (IEC 60076-10-1) for educational purposes. The Chairman supported that and stated that the Application Guide has excellent tutorial information on both transformer noise and measuring transformer noise.
The next item on the Agenda was the development of “REFERENCE Load noise levels for single-phase power transformers”. The Chairman presented measured Load noise Sound Power levels received, as provided by a number of transformer manufacturers, at a wide range of rated MVA vs. calculated load noise using Reiplinger’s Equation for both 50 and 60 Hz transformers separately. The data again showed that measured values of load noise can be as much as 10 dB higher than the levels calculated using Reiplinger’s equation. Therefore, adding 10 dB to the calculated values would represent a reasonable calculated REFERENCE levels for load noise of single-phase transformers.
The next topic was an open discussion of the purpose of developing ‘REFERENCE Noise Levels’. For this discussion, the Chairman presented slides showing how measured and guaranteed no-load noise levels of a large number of transformers compare to the NEMA TR1 levels. The data demonstrated that these levels can have a spread of as much as 25 – 30 dB
Annex J
Page 12 of 31
from the NEMA TR1 levels. The Chairman then presented two possible objectives of establishing “REFERENCE Noise Levels”. One objective is to use them as a measuring stick to determine how much lower a guaranteed noise level of a transformer is from the REFERENCE level. The second possible objective is providing ranges of sound levels for No-load and Load Noise for certain transformer classes per the CIGRE WG plan. The Chairman stated that noise levels of Power transformers should be specified based on the required sound level at the first recipient or boundary.
The attendees were encouraged to participate in the discussion on the above. Joe Foldi supported the purpose of REFERENCE noise levels as a measuring stick to determine how much lower a guaranteed noise level of a transformer is from the REFERENCE level. He also stressed the importance of specifying the noise level based on the noise level required at the first recipient or boundary. Joe commented that it does not justify spending additional money for a transformer quieter than necessary. On the other hand, Robert Ganser indicated a concern that providing REFERENCE noise levels” could result in a possible drop in quality by some manufacturers that may get relief if the “REFERENCE noise levels” are set too high, as well as possible hardship for others. It was also suggested to introduce a note that the total noise of a transformer on site could be higher than the guaranteed level if the user does not consider load noise in the guaranteed value.
It was proposed that perhaps the term “REFERENCE” is not the appropriate wording. It was suggested that perhaps a wording like “Maximum Noise Level Limit” would be more appropriate. The Chairman then presented a preliminary wording for a note to be added to Table 17 of C57.12.00 explaining the objective of the “REFERENCE Noise levels”. This wording will be circulated to members of the TF, as well as to the guest participants, to review and propose any editing needed. The Note will read as follows:
Noise Levels given in NEMA TR1 Tables for No Load noise and in Appendix – C for Load Noise correspond to noise levels of designs where no special mean (s) of noise reduction is / are used / needed. The objective of these levels is to be used as a measuring stick to how much lower a guaranteed noise level of a transformer is from these maximum levels. Specifying the noise level of a transformer should be based on the required sound level at the first recipient / boundary.
At this point, Steve Antosz reminded the TF that there was a decision made in a previous meeting of the TF to add a new IEEE table to replace the NEMA TR1 Table. This table would be incorporated in Annex C and referred to in Table 17 of the C57.12.00 Standard.
The following new items were brought up by attendees:
Measuring noise level above the transformer cover as one customer has a need for this data
Effect of temperature on core noise and load noise. The Chairman commented that available test data shows an impact of temperature on core noise in the case of some core steels; while the effect of temperature on Load noise is small and could be either higher or lower since a large number of other factors influence the magnitude of this impact. A consequence is what temperature should transformer core and load noise be measured
What Tap position should transformer load noise be measured at?
There is a need to understand the cost impact of requiring low no load and load noise transformers
Annex J

Introducing noise level on the transformer Name plate as transformers can be moved from one are to another
The Chairman suggested addressing these at the Spring TF meeting. In the meantime, the TF will attempt to collect the data needed for these items.
Time expired and the meeting concluded at 3:00 PM.

Annex J
Page 14 of 31
- As discussed in the Spring meeting, a note was added in a box to emphasize
that the loss values provided in the new table are conservative estimates.
- Ramsis Girgis noted that there is a large variation in eddy and stray losses for
power transformers and the table shows > 3MVA.
- The Chair stated that this document would not generally be used above 50
MVA, which was the upper limit in the scope of the original document. Also,
the losses in the new annex are all for distribution transformers. Ramsis
Girgis recommended a note not to use the table of loss estimates above 20
MVA.
- Motion: Ramsis Girgis to change the table from > 3000 to 3000-20 000 with
a note not to use the table above 20 MVA since these estimates do not apply
and it is suggested that the reader consult the manufacturer for specific loss
information.
- Eduardo Tolcachir suggested also adding the same caution to specialty
transformers.
- Motion: Don Ayers and seconded by Ramsis Girgis with unanimous
approval.

- This annex addresses the basis for the statement in Clause 6.2.e: “The maximum eddy-current loss density is assumed to be in the region of the winding hottest spot and is assumed to be 400% of the average eddy-current loss density for that winding.”
- This statement has raised a number of questions over the years. The Annex is based on theoretical calculations for small transformers taken from a derivation by Max Cambre. - The Chair requested all to read the annex and comment.
Appendix G reviewed:
- This annex is a collection of winding eddy and stray loss data provided by the members in various formats. - The results are quite varied for different kVA’s and voltages, demonstrating the significant differences due to winding style.
The Chair asked for volunteers to check the four examples to make sure no errors were made in transcribing to the new document format. The results were requested by Thanksgiving.
- David Walker: 6.1.1 - Dhiru Patel: 6.3 - Eduardo Tolcachir: 6.1.2 - Javier Arteaga: 6.4
The Chair noted that he has received very few comments and the document is ready to go to ballot. The Chair asked for a motion to request PCSC approval to go to ballot
- Motion: Ramsis Girgis and seconded by Phil Hopkinson with unanimous
approval.

J.8.6 WG on PCS Revisions to C57.12.00 - T. Ansari
October 24, 2016 4:45 PM Sheraton Wall Hotel
Vancouver, BC, Canada
UNAPPROVED MINUTES The PCS Working Group on General Requirements for C57.12.00 met on Monday, October 24, 2016. The Chair Tauhid Ansari called the Group to order at 16:45 and explained purpose and scope of the Task Force. Enrique Betancourt, the TF secretary, was not able to attend and Craig Stiegemeier recorded the minutes during the meeting. WG. 53 Members and 86 guests were present, and as Working Group membership stands at 76 members, we did have a quorum and were able to conduct official business.
The Agenda and the minutes from the Atlanta meeting were approved (Terry, Shem), with Mark Perkins noting that the agenda should reflect Task Force rather than working group. The agenda was corrected and there was unanimous acceptance of the corrected agenda. The minutes from the Atlanta meeting were (Sanjab Sohm, Terry) reviewed. In a vote of those attending, there was unanimous acceptance of the spring 2016 Atlanta minutes. Agenda Items were covered as follows. 1. OLD BUSINESS
A. WG Item 105, Sec.4.1, Sec.7.0 Clarification on Short circuit condition. Survey result, Survey Comments, & Discussion on topic
In Spring 2016, A motion was brought up (Ajit Varghesse/Vinay Mehrotra) as to include a statement in C57.12.00 specifying that for short circuit calculations 1.0 PU is the pre-fault voltage and that anything different has to be specified by user. The motion was amended by Mark Perkins to start first with a survey among the WG’s Membership about this proposal if this is to be discussed in TF C57.12.00.
A review of the comments from those responding to the survey was conducted. The chair sent a survey to 273, and 88 responded to the survey. The Result as follows:
Approve 58 66%
Annex J
Page 16 of 31
Approve with Comment 9 10%
Disapprove 5 6%
Disapprove with comment 9 10%
No comment 7 8%
Total 32% response 88
The approval comments were reviewed for those attending the meeting.
If we are considering real-life operating conditions for short-circuit conditions in the standards then the interconnected system should also be considered. The WG on C57.158 Guide for the Application of Tertiary and Stabilizing Windings in Power Transformers failed to consider the worst case condition for tertiary currents. This is for parallel auto-transformers when a single line-to-ground fault occurs with possible X/R ratios can produce more current in the tertiary than the infinite bus condition. The condition I am describing was the subject of a white paper written some years ago by L.S. McCormick (sic) of Westinghouse Electric which raised this concern.
- Wallace Binder
I think the discussion is good but vote for 1.0pu volts - Philip Hopkinson
Often times, pre-fault level becomes an issue at the stage of design review meeting. It would be better to state the condition somewhere in the current IEEE standard.
- Jinho Kang
A motion was brought up (Ajit Varghesse/Vinay Mehrotra) as to include a statement in C57.12.00 specifying that for short circuit calculations 1.0 PU is the pre-fault voltage and that anything different has to be specified by user
- Neil Kranich
Our transmission planning department is advising that portions of Ameren's system may see 110% as a maximum operating voltage. We believe that other utilities may be in a similar situation with the advent of renewable generation and the retirement of synchronous generators on their systems.
- David Ostrander
The discussion may shed more light on the issue hopefully by other users and suppliers to benefit the process. My personal opinion is that this should be made a requirement for Class II power transformers. 105% operating voltage is more typical for large GSU and auto transformers and would be a good level to use as a pre-fault voltage. The subject is covering the requirement in a major change wise and if not much response received here my suggestion is to go up to the WG or Sub-com level to get a wider response spectrum to help the process. This may not be allowed by the IEEE process but not being sure would like to add here for in-case type scenario.
- Bipin Patel
the requirement should be for 1.05 PU as this is defined as part of the transformer’s continuous operation capability per Section 4.1.6.1 of C57.12.00-2015
- Brian Penny
Annex J
Page 17 of 31
1.0p.u to be used unless specified by customer - Krishnamurthy Vijayan I believe this topic of pre-fault voltage for short circuit calcs should be discussed. I don’t believe we should require the level of margin discussed for ALL transformers which adds cost to applications that does not require it. I think it should be worded such that it is calculated at 100% but add some words that the user may want to increase to 105% or 110% pre-fault for additional margin at the time of tender by the customer.
- David Wallach
A review of those who disapproved was conducted.
TF would not be the place where the technical discussions should initially take place. Because short circuit tests become destructive tests if the device under test fails, a proposal to increase the applied energy level may have a substantial (and in many cases unnecessary) negative economic impact on both manufacturers and end users. I think that such a significant proposal should begin discussions in the Performance Characteristics Subcommittee itself. PCS can choose to deliberate the technical issue directly, or to assign it to your TF as a work item, or create a separate TF, or whatever. But to me it’s too big a question for the TF to handle without a mandate from the SC.
- Jeffery Britton
If there are some special considerations to be taken into account for the short circuit condition, those should be declared in the contract documentation (specifications, questionnaires, etc.), but not as a change to the standard.
- Juan Castellanos
This does not qualify for discussion. There is already a statement addressing this in 7.1.5.5(d) - Bruce Forsyth
This 110 % condition needs to be clarified and understood first. System voltages are generally limited to 105 %. Even the 500 kV system voltage that has a limit of 550 kV is truly ~ 5 % of the 525 kV reference transformer Voltage. GSUs also can not have more than 105 % of its rated Voltage, I do not think. Som there is a need for clarifications from Customers who buy GSUs and System transformers. It should not be an agree disagree vote until this whole thing about 110 % V is understood operationally. Only then one can decide what the right thing is.
- Ramsis Girgis
The voltage should remain 1.0 PU. The higher voltage is already specified in the standard as an application conditions requiring special considerations. That can be specified by the end user for this special condition without increasing cost of ALL transformers.
- Marion Jaroszewski
The 100% voltage condition has been used for many years and also is used in other world standards. If some particular utility wishes to add a special clause for prefault overvoltage, it can be addressed in their particular specification.(and many do already) Thus there is no need to add this topic to agenda
- Dennis Marlow
Annex J
Page 18 of 31
This should be discussed outside C57.12.00 - Stephen Oakes
Unless a pre-fault condition is specified, it is imperative that 1.0PU is used for short circuit force calculation. C57.12.00 adequately covers other conditions
- Dinesh Sankarakurup
100% voltage should be considered a base level, however the user may specify a higher pre-fault voltage, i.e. 110%. Rationale: I am not aware of a significant number of the short circuit failures in USA due to a weak design under current specification (i.e. 100% voltage).
- Waldemar Ziomek
Shedan CG Power – he has disapproved and still has the same opinion Vadim Rooter SPX – pre-fault condition needs to be clarified Joe Foldi clarified that the Canadian utilities have a strong opinion that the pre-fault condition needs to be 1.1 for the purposes of calculation of short circuit currents. Ed teNyenhuis – he noted that we can have this discussion as a part of PCS duties Joe Foldi suggested that we’re not prepared to have this discussion and maybe we should postpone to the next meeting. Bob Thompson – RST consulting noted that some transformers are overexcited. Ramsis Girgis noted that the voltage at the primary and secondary are limited to 5%. The excitation of the curve may be higher for certain types of transformers. Ramsis does not understand where the 110% comes from. He believes that a more basic question is to determine the basis of the 110%, as it’s an excitation issue and not a voltage issue. The 105% makes sense, as that is an actual operating voltage condition. Bob Ganzer – We have many customers that can run 110% for 24-36 hours to look at the quality. His belief was that this was a maximum value to avoid saturation and the resulting other problems, like heating. Bob noted that one could get into legal issues if the real operating voltage is not used. Mat Weise – PacifiCop asks for 105% Chris – Commonwealth Edison – they have seen conditions that during the summer when all capacitors are on and the load is decreasing when the voltage on 138kV goes up to 153kV. They then will turn on the cap banks. David Murry – TVA – the operating voltages are defined in defined in ASNI 48.1 Raj – C57.12.00 is the defining standard, and other guides also define the voltage. It should be left to the customer to call out differences. Abnormal conditions should be specified by the user. Jason Hornel – SPX – he agrees with Ramsis and Raj. Jason wants to change the working in Section 4.1.6. Guy from SMIT – Need to be careful what is changed – operating condition or service condition. This will cause an issue in low impedance high-voltage transformers. Neil Kranish – Jordan Transformer – short circuit calculations at 110% result in a stronger, bigger transformer. Not all customers want that. Sanjab Som – Siemens – this is a matter of margin Should a statement be added to the standard that the customer Chris Slatterly – FirstEnergy – they call out 110%, and they’re dealing with that 110% at a real operating condition. Black and Veatch – Need to specify the value Tauhid summarized that we should keep it at the current limit, but offer more clarification. Bob Ganser – suggested the differences between a standard and guide is that a standard must be a “shall”, where a guide offers a suggestion using “will” and “should” do something. The
Annex J
Page 19 of 31
standard is a default for protection of the transformer. Any value other than 105% at full load or 110% at no load must be defined by the individual users. Robert Thompson – asked if it makes sense that the user would be able to energize to 105% voltage, and not require that short circuit forces be calculated at that voltage. Mark Perkins noted that the TF agreed to consider the motion that 1.1pu is the pre-fault voltage. Matt Weisen – PacifiCorp is using 105%. They run their system at 105%. Shell Sain – ComEd – they don Jill Holmes – Bureau of Reclaimation – they operate at 105% and 110% of voltage. She suggested that we put Scott Digby – Duke – they do not set the operating tap to correspond to the voltage. They set it for other reasons – such as the making sure the LTC goes through neutral David Ostrander – Ameren – They operate parts of the system at 110% as a real operating condition. He’s wondering if other utilities are seeing these higher voltage levels. Upon majority in survey approved to keep the motion initiated by Ajit and Vinay, that 1.0pu be used as the pre-fault voltage and that any other value should be specified by the user. A vote was taken and 28 approval, 6 disapproval, 2 abstain. The next step is to survey the Subcommittee PCS before sending to ballot. Shamaun Hakim brought up a topic and it was decided to move this to discussion for the next meeting. 2. NEW BUSINESS The allocated time for the meeting was expended before any new business could be considered. 3. ADJOURNMENT

A call for patents was made and none were reported. The Secretary reviewed the comments from the second ballot recirculation with resolution status. New comments were not addressed under re-balloting rules. Of the 41 comments, two were rejected, five were identified as new comments and the remaining 34 comments were addressed as editorial and accepted. The standard document was then reviewed which showed the editorial changes in red. A motion was made by Rick Marek to accept the recommendations made on the comment resolution matrix. The motion was seconded by Rogerio Verdolin. The motion passed unanimously. A motion was made by John John to accept the modified standard made with the comments in red. The motion was seconded by Sukhdev Walia. Under discussion, Paul Jarman commented that the IEC editors were against the use of dual references in the document, but was working to getting the issue resolved. The last version of
Annex J
Page 23 of 31
the standard has not been recirculated as a CDV (Committee Draft to Vote). He is investigating whether present document can be circulated as both a CDV and Final Draft. It was reported by the Chairman that a question about the arc-flash information was raised at the IEC TC-14 meeting recently, but did not consider it an impediment to the standard. Joe Mango explained how his company analysed for arc-flash conditions and how they handle the transformer. The vote was unanimous to accept the modified document. A motion was made by Hemchandra Shertukda to send the modified standard out for a recirculation ballot. The motion was seconded by Rogerio Verdolin. Under discussion Masoud Sarifi commented on the complexity of creating a standard where there are many different parties involved. It was emphasized that the standard does not take away from special customer requirements. Sukhdev Walia gave a brief history of how the standard work began and the need. The question was raised as to what would happen if IEEE passed the ballot but the IEC has objections or comments. This question will be referred to IEEE for explanation. The motion for recirculation passed unanimously. With no new business, the meeting was adjourned at 10:25 a.m. Respectfully submitted, Donald E. Ayers Secretary

Page 24 of 31
The minutes of the April, 2016 meeting in Atlanta were approved as written. Old Business
• Sheldon presented the approved PAR. Bill Whitehead to update draft standard with new scope from PAR.
• Want to harmonize with IEC standards as much as possible.
New Business
• Topics for discussion in new standard, Phase Shifted Windings, Electrostatic Shields, Interphase applications, Circuit Break Interactions and Snubbers, non-classical harmonics associated with new inverters and drives.
o Some phase shifted transformers are covered by patents. Standard will only cover general phase shifted windings rather than specific examples.
o Will mention circuit breaker interactions due to use of these transformer. However, this will be covered in detail elsewhere.
• Eddy Currents and Stray Losses. Paul Buddingh- Would like guidance on Eddy currents to remain in standard because it is an issue in the field. Eduardo Tolcachir - Need to keep division between eddy and stray losses to be able to calculate currents for testing. Rick Marek thinks simple percentages are dangerous to use for complicated rectifier transformers. John John- When harmonic information is available then we use information from customer. Not always available. Vijay Tendulkar- dual secondary’s with uneven loads can cause effect on heating. % values are ok for two winding but are not good for more complicated windings. Stephan Voss - For multiple winding transformers simple values are not good enough.
• Paul Buddingh - Suggested mentioning high resistance grounding can cause common mode noise problems in drive transformers.
• - IEEE has “rectifiers” while IEC uses “converter”. Why not change? Sheldon said that title of standard has rectifier listed but scope covers the more general case. Also, need to mention rectifiers could be in source as well as in the load.
With no further business, the meeting was adjourned at 11:55. The Working Group will meet again at the Spring 2017 meeting in New Orleans, LA

J.8.13 TF on HV & EHV Transients C57.142 - J. McBride
Meeting Minutes IEEE / PES Transformers Committee
Performance Characteristics Subcommittee TF to Investigate the Interaction between Substation Transients
and Transformers in HV and EHV Applications Vancouver BC, Canada
Tuesday, October 25, 2016
3:15 PM – 4:30 PM
Grand Ballroom CD
Chairman – Jim McBride Secretary – Tom Melle
1) Welcome and Chair’s Remarks. TF objective presented: to prepare a report addressing the need to revise the C57.142 guide to extend to HV and EHV applications.
2) Circulation of Attendance Sheets
3) Initially Quorum was not achieved. It was noted that those members who had not attended two of the prior three meetings were moved to Guest status.
4) Status of TF Paper Submission • TF paper is ready for immediate submission after completion of formatting and
Annex J

small editorial changes.
5) Discussion of Additional Topics for the C57.142 Revision – Topics were:
A) Incorporation of more mitigation techniques B) Include information on stress in the transformer due to the method of neutral
grounding - Waldemar Ziomek. C) Include information on reactor switching (C37.015 and C57.21) - Pierre Riffon D) Include information on upstream and downstream interactions in low power factor
and highly inductive circuits - Phil Hopkinson
6) Attendance was retaken: Total attendance was 87, with 25 Members and 62 Guests present. Quorum (25 of 44 members) was achieved. Eleven guests requested membership and 8 were granted based on attendance of 2 of the last 3 meetings.
7) Approval of Agenda and Spring 2015 Minutes
8) PAR Discussion continued and a motion was made by Phil Hopkinson to remove the statement indicating that Reactor Switching does not apply and include some information regarding effects of reactor switching. The motion was Seconded by Sanjib Som. Motion carried.
9) Xose Lopez-Fernandez reviewed CIGRE work on white box, black box, grey box modeling methods that are described in detail in the CIGRE brochure on interactions. One of the goals for the working group is to provide standardization of the format used to identify transformer requirements. Another goal is to create a way to link the system model to the transformer model in order to study and predict possible interactions.
10) Phil Hopkinson presentation - Discussion of Mitigation Methods, Factory Testing, and Field Service Conditions related to regarding the effect of High frequency transient from breaker operation on transformer (will be available on TF web page).
A) Discussion followed as to whether certain PD techniques or SFRA analysis being studied by CIGRE A2 may be used to help judge the immunity of impulsed windings.
B) Mark Perkins commented that some circa 1960’s core-form transformers with RC
snubbers attached failed in circuits where shell-form transformers did not. The design differences should be considered.
C) Phil Hopkinson suggested mitigation possibilities should include part-winding
arrestors
D) Bertrand Poulin provided information of a transient estimation study by IREQ for GSU’s in backfeed mode that resulted in predictive voltage distribution.
E) Further discussion centered around utilizing special termination impulse, special
design simulations, and adapting winding designs for “worst case” scenarios.
Annex J
Page 30 of 31
F) Phil Hopkinson stated that in his experience, standard switching impulse testing is not necessarily helpful in preventing these types of failures. Recommendations include “Front of Wave” (aka Steep Front, Fast Front, or FFSI, VFF).
11) The Chair commented that field measurements of the transients generated very near the transformer terminal many times have a much faster front than 1 micro-second.
12) Phil Hopkinson commented that a system load will dampen the oscillations and therefore shorting the non-impulsed windings is not necessarily an adequately strenuous test. Pierre Riffon added that special terminated lightning impulse can produce much higher stress in the affected winding and suggested stronger designs and improved testing.
13) Phil Hopkinson asked if a longer impulse tail time would be beneficial. Pierre Riffon suggested that it would not be as stressful as the other suggested methods.
14) Sanjib Som suggested including an analysis of the electrical circuit prior to design of the affected transformer(s).
15) Considering the importance of the discussion, the Chair suggested forming a survey group to collect additional information. The following members volunteered: Phil Hopkinson, Mike Spurlock, Hamid Sharifnic, Akash Joshi, Shekhar Vora
16) Motion to adjourn the meeting made by Sanjib Som and the meeting was adjourned at 4:30 PM.
Respectfully Submitted, Tom Melle, TF Secretary 10/25/2016

The attendance recorded indicated that 74 out of 113 members of the subcommittee were in attendance; a quorum at the meeting was achieved. A total of 225 individuals attended the meeting; 20 guests requested membership.
K.2 Approval of previous meeting minutes, and meeting agenda
The Chair presented the Agenda, Attachment K.2, and it was approved.
The Chair requested a motion to approve the Spring 2016 Atlanta meeting minutes. The motion was made by Dan Sauer and seconded by Marcos Ferreria, and the minutes were subsequently approved by unanimous vote.
K.3 Chair’s Remarks Joe Watson is stepping down from chair position, Bill Griesacker will assume chair responsibilities after the Vancouver meeting, Kip Yule will be Vice Chair and the secretary position will be filled.
K.4 Working group reports
K.4.1 Revision of C57.12.10 IEEE Standard Requirements for Liquid-Immersed Power Transformers – Gary Hoffman See details of meeting minutes in Attachment K.4.1. A quorum was achieved. A 30-day straw ballot was conducted following the Spring-2016 meeting; draft D2.0 was compiled and transmitted to the WG membership as a proposal to approve Draft D2.0 for IEEE Sponsor Ballot. The Chair discussed the decision to use the letter (email) ballot method to proceed “quickly” and desired to see if there was consensus to go to ballot and identify remaining issues. The Chair indicated that based on the results of this letter ballot it was his intent to request approval of the Power Transformers SC at the Wednesday SC meeting to go to sponsor ballot. There was discussion that the process was not following procedures including not allowing discussion, not addressing negatives adequately, and if a true consensus had been attained. A motion was made to re-open the draft to address the negatives, however this motion did not carry. Motion to send to IEEE for final mech. review and balloting was approved.
Annex K

K.4.2 Revision of C57.93 IEEE Guide for Installation and Maintenance of Liquid-Immersed Power Transformers – Mike Lau See details of meeting minutes in Attachment K.4.2. The WG voted to form a taskforce to study the commonality between C57.93 and C57.152, regarding testing transformers before unloading and prior to placing on a pad. A straw ballot will be held regarding C57.93 draft version 1.4. A table of various electrical tests to consider performing while the transformer is under vacuum will be included in the document with a maximum test voltage of 100 VDC or 100 VAC.
K.4.3 Revision of C57.125 Guide for Failure Investigation, Documentation, Analysis and Reporting for Power Transformers and Shunt Reactors – W. Binder No meeting was held.
K.4.4 TF to Compare C57.131-2012 Standard for Load Tap Changers and IEC 60214-1 ED 2.0 for consideration of recommending adoption of IEC standard (Also WG 60214-2 Tap-Changer Application Guide) - Craig Colopy See details of meeting minutes in Attachments K.4.4.1. and K.4.4.2.
TF Comparison of IEC 60214-1 and IEEE C57.131: Chairman created a PAR for adopting IEC 60214-1 for revision of IEEE C57.131-2012. PAR is planned to be reviewed at the December or January 17 board meeting. A preview of the PAR by IEEE and IEC has brought into question the process of adopting an IEC standard which is not currently available. A working copy of 60214-1 from IEC has met some resistance. Axel Kraemer mentioned that with stability date of 2019 showing for the IEC 60214-1 document, work on a revision would likely begin after 60214-2 Tap-Changer Application guide is published, which would likely be in 2019. It is planned for a dual logo joint revision with IEEE. WG TC Application Guide IEC 60214-2: A recommendation was made to change LTC to OLTC as most joint IEEE-IEC documents have done. IEC CD and IEEE Ballot are planned in Q3, 2017, with a CDV to follow likely before the end of 2017. Next meeting planned for Q1 2016.
K.4.5 C57.140 Guide for the Evaluation and Reconditioning of Liquid-Immersed Power Transformers – Paul Bowman See details of meeting minutes in Attachment K.4.5. Draft 7 ballot results were reviewed and resolution of items discussed. The comment spreadsheet will be sent out (draft 7) for review and electronic ballot by the WG. A simple majority will be needed to recirculate Draft 7 to the Sponsor Ballot pool
K.4.6 C57.143 – Guide for Application of Monitoring Equipment to Liquid-Immersed Transformers and Equipment – Mike Spurlock Mike Spurlock will be the new working group chair to start work on the next revision of the guide. The document was published in 2012 and the next revision is due in 2023. The work will be started somewhat early since this technology changes rapidly.
K.4.7 Revision of C57.148 Guide for Control Cabinets for Power Transformers The PAR for revision of the control cabinet guide, C57.148, was approved on 6/30/2016 and is valid until the end of 2020. A motion was approved to conduct a straw ballot within the Working Group to solicit comments and recommend changes for all sections of the document. General
Annex K
Page 3 of 15
questions will also be included with the Straw Ballot to find out how widely the standard is being used and how familiar Users (utilities, manufacturers, consultants, control cabinet suppliers, etc.) are with the Standard.
K.4.8 Revision of C57.150 Guide for the Transportation of Transformers and Reactors Rated 10,000 kVA or Larger – Greg Anderson Will submit a PAR for revision. Will meet in New Orleans to start on revising guide.
K.4.9 Development of PC 57.153 Guide for Paralleling Transformers - Tom Jauch No meeting was held.
K.4.10 Development of PC57.156 Guide for Transformer Tank Rupture Mitigation of Liquid-Immersed Power Transformers and Reactors - Peter Zhao Working group did not meet.
K.4.11 Development of PC57.157 Guide for Conducting Functional Life Tests for De-Energized Tap Changer Contacts - Phil Hopkinson Working group did not meet.
K.4.12 Development of Standard Requirements for Phase Shifting Transformers - IEEE/IEC 60076-57-12 - Raj Ahuja No meeting. Work was completed in February of 2016. IEEE approved the document. The Draft can be published once IEC gives approval.
K.5 Old Business The PTSC will sponsor a tutorial on LTC testing techniques since there is a perceived need for an LTC field testing guide. Craig Stiegemeier is leading and helping organize this effort. A meeting was held in Vancouver with interested parties to coordinate the panel speakers for the tutorial. Others are requested to participate that have a testing technology that they would like to introduce or discuss. It was requested that those interested in working on a taskforce to investigate if a section on Volts per Hertz should be added to C57.116 give their name. Ramsis Girgis expressed interest in this work.
K.6 New Business A taskforce was formed to provide a recommendation if a working should be formed to write a transformer condition assessment standard guide. Brian Sparling is leading the taskforce and plans to hold a taskforce meeting before the next PTSC meeting. Joe Watson wants to form a task force to come up with a standard template for working group meeting minutes.
K.7 Adjournment The meeting adjourned as scheduled.

Additional guests that were eligible for membership, having met the eligibility requirement of attendance at 2 consecutive meetings, but did not request membership: Donald Ayers, Jeremiah Bradshaw, Jean-Francois Collin, Michael Craven, Eric Davis, James Graham, Shamaun Hakim, Shawn Luo, Joe Nims, Jow Ortiz, David Ostrander, Ulf Radbrandt, Sergiy Razuvayev, Steve Schappell, Yukiyasu Shirasaka, Andre Shor, Andrew Steineman, Gregory Stem, Shankar Subramany, Christopher Sullivan, and Barnes Wilson. The agenda was reviewed and a motion to approve was made by Eduardo Garcia and seconded by Ewald Schweiger, which was approved by unanimous consent. The minutes to the Spring-2016 meeting of this WG had been circulated to the WG membership and guests prior to the meeting and a motion to approve was made by John K. John and seconded by Ryan Musgrove. The motion passed by unanimous consent. The Chair made the requisite Call for Patents and there were none noted by those present. During the Chair’s remarks, the Chair expressed thanks to the working group and task forces for the activities since the Spring-2016 meeting in Atlanta and proceeded to discuss the activities that had been completed. A 30-day straw ballot had been executed immediately following the Spring-2016, resulting in approximately 300 comments which were in turn forwarded to the respective clause TF Chairs to resolve. At the conclusion of the resolution of the comments by the TF’s, Draft D2.0 was compiled and transmitted to the WG membership as a proposal to approve Draft D2.0 for IEEE Sponsor Ballot. The WG membership was provided the time period of September 22nd thru October 22nd to review the draft and vote on the proposal. The Chair discussed the decision to use the letter (email) ballot method, citing the Policies and Procedures manual as stating for WG’s to proceed “quickly” and desired to see if there was consensus to go to ballot, or in the process identify the remaining issues. The results of the letter ballot are as follows:
Votes received 35 out of 56 members 62.5% (quorum achieved) Approve 29 82.9% (2/3 majority, or super-majority,
achieved) Disapprove 6 17.1%
The Chair indicated that based on the results of this letter ballot it was his intent to request approval of the Power Transformers SC at the Wednesday SC meeting to go to sponsor ballot. The Chair encouraged attendees to become members of the ballot pool, emphasizing that they must be members of the IEEE Standards Association in order to do so. Clarification was also stated that
Annex K
Page 8 of 15
comments received during the balloting process must be responded to, with accepted comments going in verbatim into the document but rejected comments receiving an explanation.
Don Platts made a Motion, which was seconded by Sue McNelly, to re-open Draft D2.0 for discussion, thus nullifying the letter ballot to approve for IEEE sponsor ballot.
Don discussed reasons for this motion, stating as reasons failure to follow Policies and Procedures manual, failure to implement material documented in the minutes, terminology changes that had been made, and statements in the document that were changed to “or” statements, creating a type of “menu” not typical of a standard document. Upon request by the WG Chair for additional detail regarding procedural errors, Don stated that Task Forces that are formed are obligated to report back to the WG. The Chair indicated that this was accomplished by way of the letter ballot. Don countered that this process allowed for no discussion, again stating that the TF work needs to be approved by the WG. The Chair stated in opposition to Mr. Platts’ statement that the comment resolution and a revised draft was shared with the WG and Letter Ballot was approved.
Steve Antosz noted that 6 WG members had disapproved the proposal to approve the draft for sponsor ballot and asked what comments were made. The Chair said that should not matter and stated the concept that one person cannot hold up the process.
The motion was called to vote, with the following results: Approve 15 Disapprove 15 + Chair 16 Abstain 9
The motion did not carry. Joe Watson asked whether the Mandatory Editorial Review had been completed. The Chair said not yet, as were waiting for the approval to submit for sponsor ballot before doing so. Steve Antosz expressed concern with this process and that there seemed to be question among the WG as to whether consensus had truly been obtained. The Chair’s response was that the request for approval for Sponsor Ballot gave the WG Members the opportunity to see how the draft was revised and that the Sponsor ballot process that requires a much higher bar of 75% approval would vet this concern. Under New Business, Ronnie Minhaz requested clarification concerning section A.1.2 (VFVV OLTC regulation) around the interpretation of the phrase that the HV system voltage is presumed to be relatively constant therefore the flux density being variable when the LTC is located in the HV. There was some clarifying discussion provided by David Geibel and Sanjay Patel, clarifying that the standard has to assume voltage is stable before considering the effect on the transformer, that the nameplate voltage values set the basis (thus when HV turns change the volts/turn and thus the flux density change), and that the nameplate values are no-load based values. It was noted that the next WG meeting would be in the spring during the IEEE Transformers Committee meetings in New Orleans. The meeting was adjourned at approximately 8:45 a.m. Respectfully Submitted, Scott Digby, WG Secretary

Chair’s Remarks:
After discussion regarding the potential loss of inhibitor during the vacuum dryout of a new transformer or an in-service transformer, a motion was made motion was made by Larry Christodolou to automatically add inhibitor to 0.3% by weight after the completion of the vacuum filling and or hot oil circulation. Derek Baranowski seconded the motion and the motion carried.
There was discussion regarding testing a transformer before it is unloaded and prior to placing on a pad. Sue McNelly made a motion to establish a Task Force to study commonality between C57.93 and C57.152. Ewald Schweiger seconded the motion and the motion carried. Alwyn VanderWalt agreed to chair the study group.
The committee decided to remove all information related to safety notifications. A straw ballot will be held regarding C57,.93 draft version 1.4. Under Unfinished Business, Chuck Sweetser presented a table of various electrical tests to consider performing while the transformer is under vacuum. It was decided to include the table as part of the document with a maximum test voltage of 100VDC or 100VAC. Under New Business, Ismail Guner is proposing a guide for best practices for asset management. The Scope of proposal will include inspection, diagnosis, and maintenance of transformers. The meeting was adjourned at 3:03 pm.

Meeting Minutes / Significant Issues / Comments:
1. Meeting was called to order at 1:45 pm, October 25, 2016. 2. Chairman created a PAR for adopting IEC 60214-1 for revision of IEEE C57.131-2012. PAR is planned
to be reviewed at the Dec or Jan 17 board meeting. A preview of the PAR by IEEE and IEC has brought into question the process of adopting a IEC standard which is not available at this time. A working copy of 60214-1 from IEC has met some resistance.
a. Erin Spiewak (IEEE-SA) spoke about the reason why PAR was meeting resistance currently. Even though there is a process for adopting an IEEE standard into IEC, there IS NOT an approved process in place for IEEE to adopt an IEC standard. Discussions between IEEE and IEC about this process of adoption are scheduled to be discussed in January 2017 according to Erin.
b. This TF will not become a WG until the PAR is approved 3. Axel Kraemer mentioned that with stability date of 2019 showing for the IEC 60214-1 document, work
on a revision would likely begin after 60214-2 Tap-Changer Application guide is published, which would likely be in 2019. It is planned for a dual logo joint revision with IEEE.

Meeting Minutes / Significant Issues / Comments: 5. Meeting was called to order at 3:15 pm, October 25, 2016. 6. Chairman provided the WG a background relating to the work being done to adopt the IEC standard
60214-1 as a dual logo document preserving main technical differences between C57.131 and 60214-1 in an Annex. Annex E of C57.131 is included within the latest draft of 60214-2, Tap Changer Application Guide.
7. The latest document draft 6WD of 60214-2 was presented to the WG by Axel Kramer. The draft showed highlighted text which was reviewed at the last meeting in Dresden, Germany and showed red text for any changes to the draft done in Dresden, Germany. Some comments were made by the WG:
a. Page 8-Introduction – add ‘tap-changer’ in front of manufacturer – Axel Kraemer b. Section 11 – Storage – Axel Kraemer to work on changing title c. Paul Jarman requested to see information on manual operation of OLTC’s. Section 13.2.1 of the
draft was displayed showing information about manual operation of OLTC’s. d. Paul Jarman made a comment that OLTC instead of LTC should be adopted. The chairman
commented use of OLTC has been preferred for implementation in majority of joint IEC/IEEE documents where applicable.
8. IEC CD and IEEE Ballot are planned in Q3, 2017, with a CDV to follow likely before the end of 2017. 9. Future Work Sessions:

Meeting was held in Vancouver, BC, Canada, from 3:45-6:00pm October 24, 2016 Chairman: Paul Boman Vice Chairman: Brian Sparling
There were 21 of 64 members present. There were 52 guests present. A membership quorum was not achieved. The WG does not plan to meet at the Spring 2017 Transformers Committee Meeting in New Orleans, Louisiana.
A motion to approve the Fall 2016 Vancouver Agenda was made by Eric Davis and seconded by Roger Verdolin. However, since there was not a quorum, no vote was recorded. There were no objections or additions to the agenda.
Patent disclosure announcement: The Chair asked if there were any individuals that were aware of any patent claims might be Essential Patent Claims. The following statement was read during the meeting:
If any individual believes that Patent Claims might be Essential Patent Claims, that fact should be made known to the entire working group and duly recorded in the minutes of the working group meeting.
There were no patents claims identified. Details on patent information can be found at:

Attachment K.4.6 Revision of C57.148 Guide for Control Cabinets for Power Transformers Joe Watson: Chair, Weijun Li: Vice-Chair, Jean-Francois Collin: Secretary The working group met at 11:00 AM on October 24th, 2016 in Junior Ballroom C-D at the Sheraton Wall Centre Hotel in Vancouver, BC, Canada. 58 attendees were recorded. It was the first official Working Group meeting for this project. All meeting attendees were eligible to join the WG and since all members were in attendance, a quorum was reached. The complete attendance record is available in the AM System. 23 guests were granted membership. The meeting started with the approval of Atlanta Spring 2016 Task Force meeting minutes. There were no recommended changes and the minutes were approved. The revised meeting agenda with added Patent claim section was approved. The Patent question was asked and no essential patents were claimed. The Chair noted that the PAR was approved on 6/30/2016 and is valid until the end of 2020. The occurrence of numerous statements in the Standard saying “unless otherwise specified” was discussed with the suggestion that this could be added as a general statement instead of duplicating it all over the standard document. During the previous meeting of the Task Force to determine whether a revision was required, some Task Force members volunteered to review sections of the standard. The volunteers did not present reports, but Ryan Musgrove raised the question of whether the Standard was being widely used, and specifically how many utilities or manufacturers are using the current standard or are aware of the Standard. The group discussed polling Manufacturers and Users with these questions, but Gary Hoffman made a recommendation to do a straw ballot within the Working Group to solicit comments and recommend changes for all sections of the document. The motion was made by Gary Hoffmann and seconded by Rob Ghosh and approved unanimously. General questions will be also included with the Straw Ballot to find out how widely the standard is being used and how familiar Users (utilities, manufacturers, consultants, control cabinet suppliers, etc.) are with the Standard. The Chair stated that the Standard was not presented to the Committee with a Tutorial, which is the current practice now, and that this would have introduced the Standard to more Users. In light of this, the group should present a tutorial for this revision after it is successfully balloted. The Chair commented that C57.148 doesn’t have an objective to propose unnecessary requirements on the manufacturers. And reminded the group that each section of the document is open for discussion, and that comments need to be specific and not just general statements such as “this section needs to be reworded”, etc. This WG is open to other suggestions such as what else should be or shouldn’t be included in the standard. The Chair proposed a schedule for the straw ballot: 30 days to review. Officials will review the straw ballot results and categorize all comments. Results will be discussed at the next meeting and Task Forces will be formed to address the Straw Ballot comments. A working copy of the Standard has been requested from IEEE and will be posted on the Power Transformers Subcommittee web page on the Transformers Committee site before the straw ballot can start. The group will meet again in New Orleans, Louisiana in April 2017. The meeting was adjourned at 12:00 PM.

Annex L Standards Subcommittee – Unapproved Minutes
October 26, 2016 Vancouver, BC Canada Chair: Jerry Murphy Vice Chair: Kipp Yule Secretary: Daniel Sauer Standards Coordinator: Jim Graham
The Chair, Jerry Murphy opened the meeting calling a show of members to establish quorum which was met.
L.1 Meeting Attendance
The Standards Subcommittee met on Wednesday, October 26, 2016, at 4:30 PM in the Junior Ballroom CD. A show of hands indicated only 17 of 35 members in attendance falling short of quorum at the starting time of the meeting. Quorum was achieved later with arrival of additional members. Overall the attendance roll showed there were 89 attendees, 22 members, 64 guests, including 13 that requested membership. Upon tabulation of the circulated rosters they will be reviewed for eligibility. Steve Shull moved to approve the fall 2015 minutes with second by Steve Antosz; motion was carried with unanimous acclamation approving. Jerry then requested a review of the Agenda which was updated to on section 5.3; motion was made by Steve Shull and seconded by Steve Snyder which was carried unanimously.
L.2 Chair’s Remarks
Jerry welcomed the attendees to the final sub-committee meeting of the day and reviewed our process regarding membership requests. The chair further stated that the roster would be reviewed for further updates based on attendance at this meeting.
L.3 Standards Coordinator’s Report – Jim Graham Jim’s report is on file.

L.5 Working group reports
L.5.1 Continuous Revision of C57.12.00 – Steve Snyder The purpose of this WG is to compile all the work being done in various TF/WG/SC’s for inclusion in the continuous revision of C57.12.00 in a consistent manner. This WG coordinates efforts with the companion Standard C57.12.90 so that they publish together. The current standard was approved by the IEEE-SA Standards Board on December 5, 2015, with an official publication date of May 12, 2016. The standard is good for 10 years, but is under continuous revision and will be next balloted when sufficient new material is available.
Respectfully submitted by Steven L. Snyder, WG Chair, on October 26, 2016
Annex L
Page 2 of 4
L.5.2 Continuous Revision of C57.12.90 – Steve Antosz This is a working group by committee of task forces, for continuous revision of C57.12.90. The purpose of the WG is to keep track of the work being done in various TF/WG/SC’s for inclusion in the continuous revision of C57.12.90 in a consistent manner.
Summary The new Standard C57.12.90-2015 was approved by the Standards Board on December 15, 2015. It was published on March 11, 2016 as IEEE Std C57.12.90-2015.
Status Since this is a continuous revision document, there continues to be ongoing work in the various Task Forces. No new material has yet been submitted for the next revision. Shortly after the document was published in March 2016, it came to Steve’s attention that there was one error and one omission in the document. • There is an error in Equation (2) in subclause 8.3 Waveform correction of no-load losses, where the
exponent “2” was lost during editing. It needs to be added back. • There is a sentence in 10.8 Induced Tests for Class II Power Xfmrs, that refers to this test being
applied to terminals 115 kV and above. Since Class II now extends down to 69 kV, this sentence needs to be revised, changing the 115 to 69.
It was decided that these should be corrected immediately, so a corrigendum would need to be done. Steve took out a PAR and it was approved. With Peter Balma’s help, the Working Group got the Corrigendum done and had a few electronic meetings with the Working Group members and it was approved to go to ballot. With approval of the Standards Subcommittee in Vancouver, I will launch the ballot shortly after this Vancouver meeting. At the Spring 2016 meeting, Steve requested the three Subcommittee Chairs from Dielectric Test, Performance Characteristics, and Insulation Life to rename their 12.90 continuous revision Working Groups to Task Forces, since calling them a WG is incorrect. A WG needs a PAR and those groups do not have a PAR. The PAR exists (will exist) in the Standards Subcommittee only. Therefore, they are really Task Forces. Steve plans to take out a new PAR for future revision to the document, and will do so after the Corrigendum finishes.
L.5.3 Corrigenda for C57.12.70 – Steve Shull
Steve Shull called the meeting to order and welcomed everyone to the working group meeting for the Corrigenda of C57.12.70. The purpose of the Corrigenda was to review Annex A and correct any errors that were found in the document. A quorum was established by hand count using a members list on the screen. Steve asked for patent claims and none were made.
Steve presented the agenda. A motion was made by Jerry Murphy and seconded by Lee Mathews to accept the agenda and the WG approved it by unanimous consent. Steve noted that the minutes of the last meeting were posted and entertained a request for a motion for approval of these. Jerry Murphy made a motion to approve these minutes and it was seconded by Jason Varnell. The WG approved it by unanimous consent.
Jason Varnell made a presentation to the group for the Task Force who reviewed the document. This Task Force consisted of himself, Charles Sweetzer, and Steve Shull. This presentation will be posted on the website.

This generated some discussion that resulted in a couple of suggestions. These were that the winding diagrams should be first on the left so that a left to right flow would allow for a better understanding of the phasor development. It was also suggested that some of the phasor diagrams be reordered to help in understanding the phasor development that were used in later drawings. As well, to make the arrows of the phasors be always at the tip away from the common point on wye connected diagrams and so as to provide clarity in the clock diagrams.
This resulted in a motion by Jerry Murphy to have the task force create a new draft of the annex which would incorporate the discussed suggested changes. This was seconded by Jason Varnell and was passed unanimously.
A request came from Blake Cook to join the Task Force. Steve Shull welcomed him to the group.
The next meeting will be held in the Spring 2017.
Respectfully submitted by Steve Shull, WG Chair, on October 26, 2016.
L.5.4 TASK FORCE for Comparison of IEEE & IEC Standards for Cross Reference The task force meeting was held at 4.45pm on October 25, 2016. 4 of 5 members were present, so a quorum was achieved, 4 guests also attended, for a total attendance of 8.
The working group unanimously approved the Vancouver Meeting Agenda. A motion was raised by Hemchandra Shertukde to approve the minutes of the San Antonio, Spring 2015 meeting, Bill Griesacker seconded the motion which was carried unanimously.
A motion was then raised by Hemchandra Shertukde to approve the minutes of the Memphis, Fall 2015 meeting, Richard Marek seconded the motion which was carried unanimously.
This was followed by two presentations on comparison of IEEE and IEC standards. The first presentation was a comparison of the bushing standards C57.19.00 (2004), C57.19.01 (2001), and IEC 60137 (2008) prepared by John Graham chair of the Busing sub-committee (SC36A) and presented by the chair.
The second presentation was prepared by Tom Golner and presented by Rick Marek covering important differences between IEEE and IEC standards for high temperature insulation C57.154 and IEC 60076-14.
The task force meeting was adjourned at 5.50 pm.

L.5.5 TASK FORCE Report: Unwritten Rules & Procedures for working on and Revising C57.12.00 & C57.12.90 Steve Antosz presented his report on the procedures and rules for the compilation and editing of our two main standards: C57.12.00 & C57.12.90. Based on these recommendations, the groups that work on individual portions of these standards have been converted to Task Forces. The individual groups working directly on the material do not have PARs therefore they cannot be Working Groups. The Working Groups addressing these standards work out of this Sub-Committee and have membership determined by the chairs of the individual Task Forces that contribute to the material in these standards.
L.5.6 Working Group Report: Corrigenda for IEEE C57.163 – 2015
The Ballot of the corrigenda for IEEE PC57.163 – 2015 Guide on “Establishing Power Transformer Capability while under Geomagnetic Disturbances” closed at midnight October 14. It received 96 % response rate and 100 % approval rate. It dealt with a clarification made in the caption of Figure 13 of the Guide where the Figure showed Tie plates hot spot temperature rise measured at the top of the tie plates
Annex L

while the corresponding Figure in the referenced Paper showed those at the middle of the plates. Three minor editorial comments were received and responses were entered. The project is on the agenda for the December 6 RevCom meeting.
L.6 Old Business
• The task force for C57.12.80 working on the definition for a distribution transformer (see Spring of 2016 minutes) has had their scope expanded by a motion to a full revision of this standard. This was moved by Jim Graham and seconded by Hemchandra Shertukde. The motion carried with one objection. Clair Claiborne volunteered as chair, with Jim volunteering as vice-chair.
L.7 New Business
• Steve Antosz reported that a Corrigenda of C57.12.90 is complete and has been sent to ballot to correct the error in the core loss correction formula and the omission in the induced test clause for class 2 power transformers which was discovered after the document was published. The next meeting will be held spring 2017 in New Orleans, LA.
L.8 Adjournment
Steve Antosz moved to adjourn which was seconded by Susan McNelly, there were no objections and the meeting was adjourned by the Chair.

Old Business
Low Voltage terminals 7.2.2
Al discussed the revision to the low voltage table that was presented in the spring 2016 meeting by the low voltage terminal task force. The primary changes were the addition of a voltage component to the table, updated the cable standard reference to the most recent version and added the statement "The connection between the secondary bushings and the cable shall be fully insulated and sealed to prevent the entrance of moisture."
Al asked for comments and/or discussion in regards to the data presented in the table. No comments were made.
Dan Mulkey made a motion to approve the table as presented below. Ronald Stahara seconded the motion. The table and text were unanimously approved.

When low-voltage cable leads are specified, they shall extend 350 mm (14 in) above the top of the cover and shall be arranged for vertical takeoff. Cable insulation shall be in accordance with NEMA WC7 1998/ICEA S 65 658 or functional equivalent for continuous operation at a minimum of 90o C and 600 V. Cable flexibility shall be such that bending it into an arc having a radius of 300 mm (12 in) can be accomplished without overstressing the low-voltage bushing. The connection between the low-voltage bushings and the cable shall be fully insulated and sealed to prevent the entrance of moisture into the cable.
Tank Materials
The table detailing the minimum tank, cover and cooler thickness from 12.24 was discussed and displayed. The objective was to identify if we should have a table detailing the minimum material thickness in 12.23 and if so what thickness should be included in the table. Giuseppe Termini and several other members commented that the table has purpose in this standard and should be included
After agreeing the table should be included in the standard, the discussion transitioned to what thickness should be considered the minimum. Said Hachichi commented on the use of copper bearing steel which is included in 12.24, however concerns were expressed in regards to the manufacturability of this type of steel. In addition, Al asked if any OEM's used copper bearing steel for production of units governed by 12.23. None of the present OEMS currently use copper bearing steel. Lee Welch commented that the steel thickness from the table in 12.24 may be overkill for this product line. After discussion, the working group concluded that the best way to address this subject would be by surveying the end users and OEM’s. The survey will identify the what minimum requirements are displayed in the specs of end users, what gage steel OEM’s are currently manufacturing with special consideration to the base material used.
Pressure relief requirements
The discussion started with the presentation of background information, starting with the current text in 12.23 followed by the language in 12.39 and 12.24. The objective of the discussion was to determine what language should be included in the new revision of 12.23, in particular whether we should leave the text as is with modification or adopt the language from the other standards. Mike Hardin mentioned his successful past experience with a 1/2" UNC with nylon washer. Edward Smith commented that pipe threads are more forgiving, however with pipe threads you are counting on the thread to provide the seal and with a UNC bolt you are counting on the gasket to provide the seal. Lee Welch questioned where the fitting should be located. Dan Mulkey commented that the automatic pressure relief valve should always be on the cover and the manual pressure relief can be anywhere due to the fact the manual pressure relief is always performed in the shop. Al asked the working group if any pressure relief fittings were located on the tank wall, no one confirmed this application with certainty. From the discussion, the following text from 12.24 was modified and proposed to be the new language for 12.23
Pressure relief
A fitting shall be located on the transformer cover and used for mounting a manual pressure relief plug or an automatic pressure relief valve.
Annex M 11/21/2016
Page 4 of 9
Manual pressure relief
A ½ inch UNC bolt with a gasket or ½ inch NPT plug shall be provided that allows slow release of pressure without completely removing the bolt or plug.
Automatic pressure relief
If an automatic pressure relief valve is specified, a NPT fitting shall be provided and sized for the flow rate of the valve. The valve shall be operable by using a standard hot-line tool from above.
The group ran out of time and placed section 7.3 Accessories on the agenda for the next meeting.
We adjourned at 10:45 am. We will meet at the Spring 2017 meeting in New Orleans, Louisiana.

Brian Klaponski, Chairman; Giuseppe Termini, Secretary Revision Due Date: 12/31/2021 PAR Approval Date: 8/30/2012 PAR Expiration Date: 12/31/2017
The WG met on Tuesday, October 25, 2016 at 11:00 am with 14 members and 30 guests.
An agenda was presented and approved; and introductions were made.
The Chairman asked if anyone in the Working Group knew or had knowledge of any existing or pending patents that may affect the work on this standard. There was one positive response. Liz Sullivan from ABB stated that ABB had a patent related to high current fault inside the network transformer tank. She said they had a LOA with the IEEE from a couple of years ago.
The minutes of the March 22, 2016, meeting in Atlanta, GA were reviewed.
George Payerle made a motion to approve the Meeting Minutes as amended above. Mark Faulkner seconded the motion and the minutes were approved unanimously.
The Chairman stated that the balloted standard received a 97% approval rate. The IEEE-SA requires a 75% approval rate. The Chairman also stated that there were 47 comments received with comments from 2 balloters being negative and the other comments were associated with affirmative votes.
Annex M 11/21/2016
Page 5 of 9
Prior to the meeting a Comment Resolution Taskforce was formed by the Chairman to resolve the comments received from the balloting process however, since most of the comments were not negative, the Chairman decided to review and resolve the comments within the Working Group at this meeting.
The Chairman stated there were 3 changes related to the Mandatory Editorial Review required by the IEEE SA prior to the ballot. These were:
a) Introduction Subclause – These are the reasons for the new revision of the standard and they were added to the Introduction subclause.
b) Scope Subclause – For unknown reasons the scope submitted through the PAR does not match the Scope subclause. The Scope was revised to be consistent with the wording in the PAR.
c) Annex B – A comment was received from the mandatory review coordination raised a potential copyright issue regarding the equation used in this Annex. After much research it was discovered that the equation has been used in other IEEE standard and therefore the copy right issue was no longer valid.
The Chairman stated that Draft 9 was created after the Ballot to incorporate draft changes responding to the comments. The rest of the meeting was dedicated to the resolution of the comments ballot comments.
a) Subclause 3.1 – The word “ambient” was added next to “temperature” in the second sentence of this subclause.
b) Table 2 – A comment was received to make editorial changes to add lines for clarity purposes between columns and rows associated with this table. Plus there were some spacing issues in the table in the voltage numbers.
c) Table 8 – The headers of this table were changed to read “oil immersed” instead of “oil filled” and “ insulating liquid” instead of “fluid”.
d) Subclause 5.2 – The Working Group unanimously voted to leave this subclause as is and to consider the ballot comments received on corrosion in the next standard revision.
e) A suggestion was made by Lee Welsh (he had also made this comment in the ballot) to enlarge the figures in the standard so that they can be more legible. The Chairman stated that he will consider this suggestion and try to enlarge the print in the figures prior to submitting the final copy of the standard for publishing.
f) General Comment – A suggestion was made to renumber the dimensions in Figure 1 to remove inconsistencies (e.g.: H1 is used for the high side electrical connection, however H1 is also used to show the height between top and bottom of the network transformer with reference to Table 8).
Based on the above changes the new Draft 9 will be then submitted back through the final steps of the balloting process and approval processes of the IEEE SA.
The meeting was adjourned at 12:15 pm with the next meeting set for New Orleans, LA in March 2017.

M.3 Old Business None
M.4 New Business
C57.12 57 Ventilated Dry Type Network Transformers also falls under UGTNP. The chair commented that it is currently not meeting but that if someone wanted to, they could volunteer to make it an active working group again.
Following the working group reports, there was discussion of the patent disclosure issue. Brian Klaponski related his conversation with Gary Hoffman. The conclusion seemed to be that if a WG chair asks if there are essential patent claims and if so if a letter of agreement was sent to IEEE that should be the end of the WG chair's involvement.
Lee Welch suggested that there be a check box when we sign in to the meeting where people can indicate if there are any patent issues and also can request membership at that time.
Annex M 11/21/2016
Page 9 of 9
Brian pointed out that there has been a lot of conversation regarding cathodic protection. He suggested having a guide or an informative annex attached to C57.12.00 on the subject. He also said that maybe there is already a guide in existence. He pointed out that there are people in our meeting that have experience in that field including Bob Kinner from First Power and Jason Attard from Con Ed. They both indicated interest in working on the issue. Dan Mulkey said that PG&E has cathodic protection on the gas side of the business but not on the electric side. He also said that cathodic protection requires maintenance. There was general agreement that work on this area will be helpful.
M.5 Adjournment
The meeting was adjourned at 12:00 PM with the next meeting set for New Orleans, Louisiana on April 5, 2017.
