THE ELECTRICAL ENGINEER 1st QUARTER 201112

IIEE Incites “Electrical Safety” to An Awareness CampaignThe Institute of Integrated Electrical Engineer of the Philippines (IIEE), being devoted towards nation building and general public safety, took on a very important role in the observance of this year’s Fire Prevention Month collaborating with the Bureau of Fire Protection (BFP) and private firms such as the International Copper Association (ICA-Philippines, Southeast Asia and China Chapters) to patronize anti-fire incidents resulting from electrical system abnormalities.

The Institute has conjoined forces with these other concerned organizations to possibly educate a great fraction of the population on the facts of electrical fire and its preventive measures.

On March 26, 2011 - The IIEE’s Bureau of Fire Protection Committee held the “Electrical Safety Forum #1” at its national office in Cubao, Quezon city aiming to educate further technical practitioners and private individuals in the perpetration of their works not to consider less the safety aspect of the end users as well as to accentuate their familiarity with the standard requirements in electrical installations. The forum has gathered almost 30 participants from the different fields in the industry.

A special appearance from the Chief of the Singapore Fire Department, Mr. Tan Jin Thong, shared the various fire cases widespread in his country due to electrical abnormalities and lack of regular safety assessments from experts while the local Chief of Fire Safety Enforcement Division from the Phil. Bureau of Fire Protection, Engr. Mariano V. Joseph, enlightened the room about the statistics of fire incidents in the country with accounted damages translated to millions of monetary value and hundreds of claimed lives.

From the Board of Electrical Engineering (BEE), Hon. Jaime V. Mendoza reiterated the compliance to the existing Philippine Electrical Code on the subject of ‘Bonding and Grounding’ and pointed out how improper grounding would consequently destabilize electrical systems and

implicate a vast scope of collateral damages. Also from the BEE, Hon. Francis S. Mapile signified the aspect of Construction Safety which should not be set aside.

In line with the Institute’s advocacy still on Electrical Safety, it has signed an agreement with the International Copper Association – South East Asia Chapter (ICA-SEA), also a non-government and nonprofit organization in the presence of the IIEE President, Engr. Armando R. Diaz, and the ICASEA Chief Executive Officer, Mr. Steven Sim, dated February 10, 2011.

Under such partnership, both parties have concurred to embark at a project termed the “Electrical Safety Enforcement and Awareness (ESEA) Campaign” in the Philippines. This generous intention of the involved would constantly enhance the capacity of local safety enforcers, augment public awareness, and strengthen the enforcement of electrical regulations.

One momentous event spearheaded by the IIEE and ICA was the ‘Electrical Safety Symposium’ last March 31, 2011 at the Meralco mini theater in Pasig City. The occasion has had congregated over 64 participants from the different chapters of the Association of City and Municipal Electrical Engineers and Electricians (ACMEEE) of the Philippines, the Bureau of Fire Protection, and Safety Engineers from the industry. The Project Manager for South East Asia Building Wire Program and in charge of the electrical safety and connectivity program in China, Ms. Jessie Lei, took the pleasure to introduce the international scaffolding of the ICA organizations and the underlying principle behind it.

Notable insights from the current Director of Fire System Research Office of the China Academy of Building Research, Mr. Li Hongwen, were centered on the ‘Preventive Inspection Technology on Electrical Fires ‘and their research. Some of the mentioned causes of Electrical Fires, as corroborated

by their research in China, include arc shorts, loose connections, harmonic influence – overload of the neutral line, bad heat radiation and electrical facility arrangement. Referencing on statistics though, the major cause of electrical fires in China is attributed to loose connections accounting to about 8.98% from 2003-2007.

The final speaker of the event, Mr. Chen Kun, has had several and almost simultaneous affiliations in the China wires and cable industry. His emphasis was on the issues on the application of Copper-Clad Aluminum conductor. A highlight in his report regarding the choice of conductors, it is imperative that any decision considered should not neglect nature’s scarcity of resources. As a major principle “from grave to cradle” implies, there should be an application of just a single conductor, either Copper or Aluminum, as far as practicable, to avoid wasting of inseparable bimetal composite of conductors.

14 THE ELECTRICAL ENGINEER MAGAZINE 2ND QUARTER 2010

A Tribute to Engr. Edward L. Mendoza


He had a passion for excellence, surpassed only by a passion for learning.

The preceding sentence would most appropriately describe Engr. Edward L. Mendoza. He proved that one is never too old to learn. He coped well in the fast-paced world of innovative concepts and electronic gadgets.

While he continuously improved himself, he improved others as well. He mentored many graduates as well as new professionals. He motivated those who have met with adversity and those who were scared to take that one big step. He was always willing to help. He believed in “paying it forward.” He was Teacher, Mentor, Partner, Friend, Adviser, Father, Brother.

Engr. Mendoza was a Professional Electrical Engineer and a Certified ASEAN Engineer.

Under his leadership as president of IIEE in 1996, the IIEE, in partnership with the Board of Electrical Engineering (BEE), became actively involved in the dissemination and implementation of RA 7920, known as the “New Electrical Engineering Law”, through various lectures and dialogues conducted during IIEE’s regional conferences and conventions.

It was also in 1996 when the Ozone Disco Club fire tragedy occurred, where more than a hundred young people perished. Engr. Mendoza appeared as an expert witness during the Ombudsman hearings on the Ozone fire.

Also, during his term, the current IIEE By-laws were passed. A major provision of the new by-laws was the formation of the Council of Former Presidents (CFP), composed of former IIEE National Presidents who are still active in the affairs of the Institute. Since then, the CFP has served as Adviser to the IIEE Board on national issues.

The creation of IIEE’s first foreign chapter, IIEE Saudi Arabia, also materialized during Engr. Mendoza’s incumbency. Other milestones during his term were:

After his term as IIEE National President, he was elected as National President of the Society of Philippine Electrotechnical Constructors and Suppliers Inc.(SPECS) in 1998, 1999 and again in 2006.

Engr. Mendoza served as member of the Board of Electrical Engineering, under the Professional Regulation Commission (PRC), from 2002 to 2009.

He also served as president of the ASEAN Federation of Electrical Engineering Contractors (AFEEC) from 2004 to 2007 and an officer and, later, lifetime-adviser, of the Federation of Asia-Pacific Electrical Contractors’ Association (FAPECA). Both organizations are composed of contractors of ASEAN nations. The members meet annually in one of the ASEAN member-countries.

He was a consultant of the Department of Public Works and Highways (DPWH) for the revision of the Implementing Rules and Regulations of the National Building Code.

Engr. Mendoza also served as the Chairman of the IIEE Training Institute. He also served as the President of the IIEE Foundation (IIEEF) from 2001-2005.

Congestive Heart Failure (CHF) is a disease, usually, of unknown causes. Ed believed that his CHF was aggravated, or even probably caused by his obstructive sleep apnea.He volunteered to campaign for better awareness of the possibility that obstructive sleep apnea is a culprit in many diseases. Sleep apnea, which is common to snorers, is a condition whereby the flow of oxygen to the vital organs is obstructed due to many causes. It is important that you have yourself checked for this condition, and maybe improve, if not altogether save, your life.

The family of Edward L. Mendoza invites the readers to share with them stories of how Engr. Mendoza touched their lives by emailing them to [email protected]. Comments on this article may also be sent to the same email address.

Engr. Mendoza was tireless and prolific as a lecturer on various issues, among which are RA 9136 known as the Electric Power Reform Act (EPIRA), RA 4566 known as the Contractors’ Licensing Law, RA 7920 known as the New Electrical Engineering Law, and PD 1096 known as the National Building Code (Electrical Provisions).

As a member of IIEE’s Advocacy Group, Engr. Mendoza organized in September 2010 the well-attended forum entitled: “Powering Up for Open Access: An Assessment of Retail Competition and Open Access Readiness of All Electric Power Industry Stakeholders.” The forum aimed to draw out from the participating stakeholders their pending concerns and to assess their readiness for retail competition and Open Access and to provide guidance for the implementing government agencies in formulating appropriate rules to ensure the successful implementation of retail competition and open access. It was supported by the different distribution and utility companies and concerned government agencies.

At the time of his passing, Engr. Mendoza was the President and Chairman of the Board of ENERGYOPT INC., a pioneering knowledge process outsourcing (KPO) company engaged in energy portfolio management and the buying of power. He was also President and Chairman of the Board of DSM Energy and Efficiency Solutions, Inc. , which provides consultancy services for demand side management and energy efficiency initiatives.

Following are excerpts from emails sent to the family:

Ed was a very passionate guy when it comes to work, especially for the welfare of his colleagues in the electrical engineering industry. He unselfishly shared his time, talent and even his resources to help in the development and advancement of the electrical practitioners, which, eventually, will improve the Filipino nation - Francis Mapile

. . . From then on, he never declined another invitation to sing. In fact, when everybody was warmed up, we could not stop him from singing. Before long, he became known to us as the Filipino who does not stop singing. We shall greatly miss him. On the other hand, his singing and his signature smile will always stay with us. - Chun-Kay Lau, HKECA, FAPECA

. . . He had a very positive outlook in life and a very good sense of humor. . . He was very passionate and dedicated as he put his heart and soul in all the things he did – this truly inspired all the people around him. He will forever be remembered through all the great work he has done, all the hearts he has touched, and all the precious memories we shared with him. – Kathy Mendoza

Ed was also very good company, professionally and socially with Karaoke being his specialisation. This good natured approach broke down many barriers, ensured outcomes were delivered and created solid bonds. In this vein during a FAPECA meeting in Vietnam, over a few beers was formed the 4 musketeers of Ed (Philippines), myself (Australia) with James Kang and Yon Bradford of Korea. – Peter Glynn

He is such a nurturing boss, I learned all the facets of basic management in Interface, from Administrative to Basic Accounting, Marketing and Purchasing. Where I am now in my career and how I become successful in my own right are all credited to my training from Boss Ed. I learned from him the work values of perseverance and resiliency, which he manifested to all of us. – Maribel Umali

I think that I would remember Ed Mendoza best for his Elvis Presley impersonation during our heydays in IIEE. That was really one of his finest moments. – Gigie Penalosa

. . .he boosted my confidence especially in public speaking. . . At kahit super dami ng achievements niya, he still remained humble and helpful. What I loved about him is never siya naging madamot sa mga alam niya. He is also known for his "hindi boring" na presentations - Anne Relucio

Cover Story

From “Di-yar-yooooo!” to CEO

“He who goes out weeping, carrying seed to sow, will return with songs of joy, carrying sheaves with him.”

-Psalm 126:6By Gil R. Miranda

“Di-yar-yoooo!” is a common street sound. It is an urban symphony in a variety of traffic sounds in a busy city street. It is the sound of a new day -another life’s struggle. To some it may be a sound of hopeless effort to survive, a cry of despair. To Armando R. Diaz, it was once an optimistic window of hope.

Armando R. Diaz is a radio ham, a gun enthusiast and a professional elecrical engineer. For him, the sound, “Di-yar-yoooo!” is a reminder of his early childhood and his initial steps on a stairway that will lead to his dream.

A son of a humble cigar maker and a plain housewife, he is the fourth child in a brood of six. He saw his youth running barefoot, wading in flooded streets of the fish port town of Malabon, Rizal on rainy days. And during summer, he would burn his foot soles on the blistering heat of asphalt roads selling newspapers to keep himself in school.

In 1968, after a seemingly endless struggle, he finished at the Arellano University. Settled on breaking away

from the hells of dearth, he then pressed his way to college by blowing notes in a trombone reed.

He played baritone in the college band. In 1973, he graduated with a degree in Bachelor of Science in Electrical Engineering at the Mapua Institute of Technology.

As soon as he stepped down from MIT’s graduation stage, Engineer Armando R. Diaz’s career as an electrical engineer immediately began. He was a Start-Up Engineer at Honeywell Instrumentation in

1974-79. Five years later, he became a chief engineer at the International Rice Research Institute, where he designed and supervised the operation of Phytotron, the first bio-climactic laboratory in the Far East. He might have missed the cruel challenges in the callous streets of Malabon that he dared to venture into more stimulating tests of his abilities. In 1992 to 1994, he supervised and handled the operation of Ramada Hotel’s Refurbishment Project as a Chief Engineer. In 1994 to 2001, he was Assistant Vice President for Engineering of Uni-Lonseal-Mitsui

(Phl-Japan Co.) handling the start-up, commissioning, supervision and operation of Calendar Six’s P220M Expansion Project . In 2001 to 2007, he was the Engineering Manager of Universal Robina Corp. (BOPP Division) responsible for the start-up, commissioning, supervision and operation of its Line 2 Expansion Project, which was a P6.0B investment by J.G. Summit.

Presently, Engineer Armando R. Diaz is a Director and CEO of various companies involved on Design, Consulting Services and General Construction.

Engineer Armando R. Diaz holds licenses in Professional Electrical Engineering. He is a Certified Plant Mechanic (First Place) and an Accredited Pollution Control Officer. He is also an ASEAN Engineer with Registration No. 408 awarded in 2007.

Engineer Armando R. Diaz is a proud recipient of important awards such as 1998 Most Oustanding Electrical Engineer Practitioner in Industry of

the Philippines, 2006 IIEE Grade of Fellow and 2010 Most Oustanding Alumni, MITEEAA.

While Engineer Diaz’s romance with the Institute of Integrated Electrical Engineers (IIEE) stated in 1978, it was in the year 2006, when he was elected as IIEE’s Governor at Large, that true love bloomed. He decided to resign from Universal Robina

Corp. to give more service time to the Institute. Engr. Armando R. Diaz’s service record in IIEE showed that he became president of the Institute’s Laguna, Batangas, Cavite Chapter in 1978, barely a year after he joined IIEE. From a thriving single chapter, he worked to expand the organization into flourishing thirteen chapters. After which, he handled other responsible positions in IIEE. He was Region IV Governor in 1983, National Auditor and Treasurer in 2007, Vice President for Technical Affairs in 2008, Vice President for Extenal Affairs in 2009, Vice President for Internal Affairs in 2010 and finally the National President in 2011.

Truly an electrical engineer in heart and soul, Engineer Diaz’s vision is now focused on new avenues for IIEE to trek on its quest towards nation building and the espousal of progress in modern industry. As he takes over the helm, he drew what he called the 4-circuit program, which aims to give more muscle to the institute,

advocate membership strength and professional conpetence, pencil in few functional policies, and emphasize the reduction of the industries’ carbon print on the environment.

THE 4-CIRCUIT PROGRAM

The 4-Circuit Program is IIEE President Engr. Armando R. Diaz’s line up of activities envisioned to advance the functions of the IIEE and rightfully lead the organization towards the triumphant achievement of its objectives. Aimed to carry out the organization’s nationwide service to its members and the community, the program spreads in four service spheres conferred as circuits and given the acronym WENS, which could also mean West, East, North and South signifying the direction addressed to the four corners of the country where its members settle and practice their professions---areas IIEE intends to reach. The 4-Circuit Program encompass.

W- elfare which inspires to advocate the members’ professionalism and well-being. This also concerns the members’ advancement in the performance of their day-to-day expertise, duties, and responsibilities, assuring excellence in their field and aptness to modern day technological standards and requirements.

E- cology which is directed towards the necessary human awareness in environmental balance and sustainable energy, adoption of new methods, research support, and the practice of sound and devout utilization of non-renewable energy.

N-eo Policies aimed at updating non-functional organizational management and executive policies and create novel contemporary guidelines that would better benefit the organization and advance at its best the Institute’s objectives.

S- upport on the other hand covers the enhancement of the organization’s financial position and the creation of innovative schemes to pool in more funds for the prudent implementation of projects harmonious with the organization’s goals, the interest of the members, and contributory to the progress of the nation.

This term promises sincere and wise implementations of programs related to these circuits and give the Institute a new image that would reflect its members’ professional capability and recognize the Institute’s role in nation building and progress continuance.

Meralco Clarifies Settlement Agreement Issue

Meralco clarified reports that an injunction order issued by the Court of Appeals (CA) indefinitely stops an agreement that would allow Meralco to pass on to its consumers P14.3 billion it owes Napocor.

In a statement issued today, Meralco clarified that what the CA did was to temporarily halt the proceedings at the Pasig City RTC. It will be recalled that a petition was filed by Meralco with the Pasig City Regional Trial Court (RTC) to seek the declaration of the court that the Settlement Agreement, independent of the pass-through provision which is reserved for approval by the ERC, is valid and binding.

Both the Office of the Solicitor General (OSG) and Meralco are given 30 days to submit their respective positions on the matter. The CA is then expected to resolve whether or not to grant the OSG’s petition to revert the issue to arbitration.

Hence, the injunction issued by the Court of Appeals could not have prevented Meralco “from imposing extra charges on its customers in order to pay its P14.3 billion liability with the National Power Corporation (NPC)” since it was not the subject matter of the proceedings before the Court of Appeals or the Regional Trial Court (RTC).

Meralco explained that the injunction was only intended to restrain the RTC from conducting further proceedings pending

resolution of the petition filed by the OSG before the Court of Appeals, so as not to render the same moot and academic.

Meralco emphasized that the Settlement Agreement is valid and binding and Meralco signed the Settlement Agreement to protect its customers from additional costs since Meralco only paid NPC for electricity that was actually consumed.

The issue on the pass-through of any amount under the Settlement Agreement is still within the regulatory authority of the ERC and outside the jurisdiction of the RTC. In the meantime, however, the ERC has suspended the proceedings on this matter pending the resolution by the RTC of the validity of the Settlement Agreement. Nonetheless, the decision to pass through any amount shall still be subject to ERC approval.Meralco further clarified that the TRO earlier issued by the CA was not intended to prevent the RTC from enforcing the alleged Order or Decision affirming the validity of the Settlement Agreement, since the RTC never issued any such Order or Decision. The TRO merely suspended the proceedings at the RTC for a period of sixty (60) days, which expired last February 1, 2011, while the Injunction only effectively extended the TRO until the CA is able to decide on the case.

In the meantime, Meralco assured that the injunction order does not in any way affect Meralco’s delivery of electric service to its customers and does not impact on its rates to its customers. www.meralco.com.ph

February 16, 2011

The Energy Regulatory Commission (ERC), on 17 February 2011, issued Resolution No. 1, series of 2011 which adopted the amendments to the Revised Rules for the Issuance of Licenses to Retail Electricity Supplier’s (RES). The amendments to the rules resulted from the consideration of comments solicited from industry stakeholders and the general public. The Revised Rules prescribes the qualifications and criteria for licensing suppliers of retail electricity which includes, among others, a demonstration of their technical and financial capabilities and creditworthiness. A RES can start selling electricity only once the regime of open access and retail competition takes place.

The Revised Rules aim to ensure consumer protection and enhance competition in the retail electricity market. The key amendments include the following: (a) the term of RES License is changed to five (5) years; (b) the basis in the computation of the RES License Fee include the capitalization or the total capital invested into the business; or in the event an applicant has two or more businesses, the capitalization allocated for the supply business; or two or more business which are electricity

related, the capitalization shall be based on the ERC-approved BSUP (Business Separation Unbundling Plan); (c) a mandated 30-day notification to the ERC by a DU if it intends to operate as a Local RES; (d) proof of financial capability if RES applicant is new and an affiliate of another company.

The draft amendments to the Guidelines for the Issuance of Licenses to RES was posted on www.erc.gov.ph for solicitation of comments for a period of thirty (30) days and the second draft for a length of ten (10) days. Major industry stakeholders provided their inputs and concerns and which were considered by the ERC towards this final version. The amended rules will become effective fifteen (15) days after publication in a newspaper of general circulation.

“The ERC is ensuring that the rules required for a fair and com-petitive retail electricity market are in place so that a smooth transition to a regime of open access and retail competition happens,” ERC Chairperson Zenaida G. Cruz-Ducut stressed. www.erc.gov.ph

DOE Allays Fears of Possible Oil Supply Disruption

The Department of Energy (DOE) has allayed fears about any possible disruption in the oil supply requirements of the Philippines.

At the International Energy Forum (IEF) held on February 22, 2011 at Riyadh, Saudi Arabia, Energy Undersecretary Jay Layug re-affirmed the projections of the International Energy Agency (IEA) and the Organization of Petroleum Exporting Countries (OPEC) of the 2011 oil market situation characterized by a high level of spare capacity, in both upstream and downstream, relatively high Organization for Economic Cooperation and Development (OECD) commercial inventories and increases in oil supply. The IEF reiterated the Joint IEA-IEF-OPEC Report on the Symposium Energy Outlooks held last January 24, 2011, also in Riyadh, that oil resources, both conventional and non-conventional, are sufficient to meet future demand.

The Republic of the Philippines, through the DOE, has affirmed its support for the IEF Charter that serves as a platform for informal, open, informed and continuing global energy dialogue among its membership of energy producing and energy consuming States. In his formal statement of support on behalf of the Philippines, Layug emphasized the need for promoting a better understanding of the benefits of stable and transparent energy markets for the head of the world economy, the security of energy supply and demand, and the expansion of global trade and investment in energy resources and technology. He also raised the importance of identifying and promoting principles and guidelines that enhance energy market transparency, stability and sustainability.

The IEF is the world’s largest gathering of energy leaders from powerful countries accounting for more than 90% of the global oil and gas supply and demand. Aside from the member countries of the IEA and OPEC, other key players are Brazil, China, India, Mexico, Russia, and South Africa. Amidst the unfolding events in the Middle East and North Africa, the unparalleled cooperative discussions and dialogues at the IEF Extraordinary Meeting resulted in further strengthening the roles of producers and consumers to achieve win-win solutions. It is in the interest of global energy security that IEF created an enhanced framework for shared analysis of the dynamics of energy trends and greater data transparency to provide a more in-depth understanding of what is actually happening in the energy market, oil inventories, and movements in supply and demand.

It is in this context that Layug confidently advises the Philippine consuming public that there are no oil supply shortage issues. Based on official reports, OPEC has assured that there is sufficient global oil supply to address global demand for oil in the short and medium term periods. In its efforts to ensure supply security, the DOE has also obtained assurances from the two major players in the downstream oil industry, Shell and Petron, that there is nothing to worry about.

“The current volatility in the market is unfortunately influenced by political events in some Middle East countries,” added Layug.

The IEF members encouraged IEA, OPEC and IEF to continue their efforts and take the IEF work forward in order to help mitigate energy market volatility. Mitigating energy market volatility and future uncertainty remains of crucial importance to stabilize energy markets and facilitate energy investment, which would also benefit the recovery of the global economy. This requires further progress on achieving better data transparency in both the physical and financial markets, on putting in place appropriate, internationally coordinated regulation, as well as on arriving at a better common understanding of energy market trends and energy outlooks. The next IEF Ministerial Meeting will be held in Kuwait in 2012. www.doe.gov.ph

Massive deployment of information and communication infrastructure in operating, monitoring and control of electric power systems. This is Smart Grid. This is the vision of a controllable, observable and self-healing power system using smart grid technologies. Communication technologies like fiber hybrid and broadband over power line will enable the data and signal transfer from smart meters, automation and control sensing devices, high end system control centers interfaces in a highly visual environment, and intelligent electronic devices (IEDs). Sensing and measurement devices will be employed for which information data flow is aimed at facilitating wide-area control and protection (WACP) at the bulk power systems and dynamic control and automation at the distribution level, and other applications such as remedial action schemes, substation equipment monitoring and dynamic line rating.

As the National Energy Technologies Laboratory (NETL) reports, one of the benefits of the smart grid is higher level of power system reliability through reducing cost of interruptions by reducing the probability and consequences of widespread blackouts [1]. In this premise, the information and communications infrastructure is assumed to have no failure mode which is not always the case. Seminal work on the new framework of power system security emphasizes that the failure or misoperation of information and communications systems in operating and control of power systems can be fatal as evidence by past experiences of large outages [2].

The following are some scenarios for information and communications equipment failures:• A sensor device utilized in monitoring transmission or distribution outages which failed to send the right signal, or send the right signal at the right time (i.e. failure of information data flow and communication link) may cause further delay in restoration.

• A failure of a component of the WACP control system may cause inadvertent action from the automated operator or from the human operator in decision-making (i.e. failure of information data flow and communication link) which may result in unnecessary loss of load or forced outage of an energy resource.

• An erroneous display in the man-machine highly visual interface software due to non-updating of communication packets (i.e. failure of information data flow and communication link) which results in unobservable power system state which renders the human operator blind and thus may produce uncontrollable cascading outages.

These are only some of the possibilities of the failure of information and communication technologies when used for operating, monitoring and controlling the electric grid.

Conventional power system reliability has three levels [3]. It is assumed. in this case, outages are born out of failures in electrical components. In the past, any failure in information and communications such as malfunction of Automatic Generation Control (AGC), governor and excitation control are charged to the generating resources. For transmission and distribution systems, any protection device error due to communication failure is charged to a transmission and distribution branch or component. This is an acceptable assumption since information and communication equipment is not as massive as with the Smart Grid.

With the high dependence on information and communications technologies in the operation and control of the electric network, we propose a new framework for the hierarchical levels of power system reliability. In the figure below, information and communication facilities are given weight for outages and loss of load in the grid. Unlike in the past, it is appropriate to charge an outage to information and communications facilities especially if the root cause of the outage and further delay of restoration is due to smart grid technologies failure.

Figure 2. New framework for analysis of levels for power system reliability considering Smart Grid.

As more and more smart grid technologies are being installed in electric power systems, we foresee equipment reliability data collection to be what is depicted in Figure 3.

The Smart Grid is aimed at increasing the level of the reli-ability of the electric power network. It is important to quantify the contribution or non-contribution to the level of system reliability thereof of the information and com-munications infrastructure to be utilized to enable the vi-sion of the Smart Grid. Quantification of the contribution of information and communications facilities to the reli-ability level may be used to measure the benefits of the Smart Grid.

HONESTY: A Lost Virtue?FORTUNATO C. LEYNES

Chairman, Board of Electrical EngineeringProfessional Regulation Commission

In her last lecture of the recent semester, UP Professor Solita Monsod talks to her students about acting with honor and integrity. She further asked them if they think that cheating is very unusual. However, the truth of the matter is that it is becoming “very usual” in the university which “bothers her so much”. She further reminds her students that “cheating in small things is going to lead to cheating in the large things.” Thus, she urges them not to cheat as she emphasized that “as you cheat, you are no longer part of the solution anymore, … and you are going to be very much part of the problem.”

These are very encouraging words for the students to contribute to change in our community.

However, this is not the case in the licensure examinations, particularly in the September 2010 licensure examinations for Registered Electrical Engineers (REEs). In the “General Instructions” to examinees, CELLULAR PHONES, beepers, portable computers or similar gadgets/devices are prohibited inside the examination premises/rooms. Despite the instruction, several calculators and cellular phones were confiscated by the proctors during the Mathematics

subject of the examination—there were three cellular phones and two calculators found in different testing rooms.

The three cellular phones were in “Silent” mode so that the messages received by the units will not be noticed by the proctors. One unit was deliberately painted white so that it can easily be concealed.

While the two calculators look like scientific calculators in plain view, scrutiny of these calculators revealed that the display screens are

actually that of cellular phones. One of these gadgets even has a camera.When further dissected, a calculator, a Casio fx-100W, was found to have been deliberately tampered and embedded with a Nokia 6700 camera phone.

Further examination of the said calculator cum camera phone revealed stored images of questionnaires used in the mock board examinations.

Investigation of the messages contained in the “Sent” folders of all these calculators and cellular phones further revealed messages containing questions actually given in the licensure examinations for REEs

BEE Corner

The messages stored in “Inbox” folders contained answers to the questions given in each of the three examination subjects for REEs.

While these high technology gadgets have been confiscated in the Mathematics subject, the first subject in the board examinations for REEs, these cellular phones continued to receive messages containing answers to test questions given in Engineering Sciences and Allied Subjects (ESAS) and Electrical Engineering Subjects (EE). Therefore, there were more mobile phones and/or tampered calculators cum cellular phone that were still at large during the examinations. It is quite unfortunate that it will require a court order to force the Telco services provider to

reveal the owners of the numbers of these four cellular phones.

The Professional Regulation Commission (PRC) is conducting its investigation, and the Board of Electrical Engineering is coordinating with all concerned agencies to prevent the recurrence of similar

incidents of cheating in licensure examinations for REEs. Summons have been served to the five (5) examinees who were caught in possession of the confiscated cellular phones for violating the “General Instructions to Examinees”. If after due process these violators cannot prove their innocence, the Board has the power to perpetually bar them from taking future REE licensure examinations. Moreover, the results of examinations of those violators who took the licensure examination for Registered Master Electrician (RME) will be voided and the RME license of those who already possess it will be revoked.

Honesty should not be a lost virtue. Whereas excellence may be measured by the achievements one makes, the manner of achieving them makes or breaks its worth. Honor should come before excellence, for at the end of the day, integrity still remains the measure of the value of an individual.

TROUBLESHOOTING OF ELECTRIC MOTORS

Technical Feature

A Technical Paper from the Electric Power Research Institute (EPRI)

Energy conversion is accomplished through the use of various types of rotating machinery. Energy is typically converted from one form to another such as mechanical to electrical and vice versa. Most machinery used in converting electrical to mechanical energy has a similar construction. These machines have a magnetic circuit that is used to concentrate the magnetic flux, windings used to carry electrical current, and a support structure that is typically made up of metallic material. Electric motors are used to convert electric energy into mechanical energy.

2.1 Motor Components

There are three essential components that make the operation of an electric motor possible. The windings, which receive current from an electrical supply system, the active iron (stator and rotor cores) that provides a path for magnetic flux, and the enclosure (stator housing) with other structural support elements, make up an electric motor.

The stator housing protects and supports the stator core and windings. The support structure for most electric motors consists of two endbells (bearing housings) and a stator frame. The stator frame and endbells are often made of cast iron, fabricated steel or in some instances cast aluminum. With horizontal motors, the stator housing with mounting feet usually doubles as the mounting system for the motor. Vertical motors are usually anchored or supported by a lower mounting flange. Rotor shafts are usually carbon or special steel alloy.

The stator frame houses the stator core that is composed of stacked, insulated, laminated steel punchings, with slots that allow for winding placement. The stator frame also provides support for brackets and rings that help stabilize the winding endturns. The endbells contain the bearings, which allow for correct positioning of the rotor with respect to the stator and support the rotor. Correct positioning of the rotor will maintain sufficient, uniform air gap between the stator and rotor. The endbells of large motors may contain air baffles, which aid in the ventilation of the core, windings and bearings.

The stator windings receive the applied voltage and are so arranged as to produce a rotating magnetic field within the confines of the stator. These windings are made of magnet wire, which is formed to make coils. The magnet wire is coated with an insulating material, which provides turn-to-turn, and phase separation between each wire or wire coils. The coils are further insulated by layers of insulating material to provide electric isolation from the stator core. The coil ends are brought out, connected and insulated to form the required series or parallel circuits.

Both stator and rotor cores are made of low loss insulated laminations that are stacked, aligned and clamped. Thin laminations are used to reduce hysteresis and eddy current losses, which in turn minimizes core heating from potential stray currents. The rotor core is inside the stator core and the two are separated by an air gap. Magnetic flux passes across

the air gap to complete the magnetic circuit. The magnetic flux induces a voltage in the rotor conductors and produces torque, causing the rotor to rotate.

Various types of electric motors will be briefly described in the following sections.

2.1.1 AC Motors - NEMA Type, Squirrel Cage Induction Motors, Up to 200 Horsepower, 600 Volts and Lower

2.1.3 Wound-Rotor Induction Motors

Stator winding, stator core, rotor core, shaft, and bearings are similar to squirrel cage induction motor components. Other design features include:• Rotor Winding: Insulated conductors forming a 3-phase winding• Slip Rings: Steel, brass or bronze rings connected to a 3-phase winding• Carbon Brushes and Brush Rigging: Carbon brushes fitted with flexible copper wire cables called pigtails are mounted in brush holders with springs and some have tension adjusting devices. Carbon brushes ride on slip ring surfaces to conduct rotor current to the controller.

Stator components are the same as for AC induction motors 1,000 hp and above. Other design features include:• Rotor– Winding: The synchronous motor has an insulated rotor winding consisting of copper conductors in a concentrated salient pole field coil. It also has a damper winding that is used for starting the motor.– Core: The synchronous motor usually has salient poles that are attached to a central rim by bolts or dovetail connections.– Shaft: Carbon steel or special steel alloy– Slip Rings: Steel or bronze slip rings are mounted and insulated from the rotor shaft, with electrical connections to the insulated field windings.• Rotating, Brushless Exciter: Instead of slip rings, the motor may have mounted on its shaft, a rotating alternator with rectifier diodes to supply the insulated field winding with field current.• Carbon Brushes: Where slip rings are furnished, carbon brushes, and brush holders are used to supply the insulated field winding with field current.• Bearings: Bearings for high horsepower, low rpm, vertical type motors are oil-lubricated, usually of the sleeve type for guide bearings and disc or pad type for thrust bearings.• Frame: Usually fabricated from carbon steel plate.

REDUCING INRUSH CURRENT THROUGH AN HOSPITAL EQUIPMENT PREVENTED FREQUENT FAILURES

DEAN. A. S. SEMPIOCorporate Business Group – Technical Services

MERALCO, PhilippinesEmail: [email protected]

Introduction

Computers and electronics are found almost anywhere today. They dominate the controls of your television set, manufacturing equipment and even in the specialized field of diagnostic medicine.

Computers provide flexibility and ease of operation to medical diagnostic equipment; this in turn, has pushed the capabilities of these machines to levels unheard of before. Computers in diagnostic machines can provide detailed images of the brain without having the patient risk an operation or make doctors see how a certain drug will affect a patient. The advances in the field of electronics and computers makes one forget that some things that haven’t changed much since the last half century. One of those things is power supply.

Diagnostic equipment is invaluable to medical practitioners as they rely on them to provide information that will provide insights on the condition of patients.

Hospital Equipment

The hospital’s diagnostic equipment are among the most expensive but very valuable tools available today. It is not surprising that advances in medical equipment aided medical practitioners to accurately diagnose ailments and literally save lives. Hospital administrators are understandably concerned about the reliability of their equipment and in turn, concerned about the quality of power of their electrical system.

In this study, a hospital’s medical equipment has been experiencing frequent failures despite the presence of a UPS regulating the equipment’s power supply. The equipment vendor has given up on the frequent failures and has finally blamed the power company on the cause of the problem. The hospital is not willing to write off the equipment, as they are relatively new and expensive.

Power quality engineers were consulted by the hospital administrators to seek for solution on their problem.

Power Quality Study

The Power Quality engineers interviewed the actual users of the hospital equipment and gained some insights on the history of the equipment. It seems that despite being brand new, the diagnostic equipment never functioned for more than 6 months without experiencing failure. The installation of a UPS to regulate the supply voltage and a Transient Voltage Surge Suppressor (TVSS) did not mitigate or even reduced the frequency of the failures. The Power Quality engineers installed a Power Quality Analyzer at the point between one of the diagnostic equipment and its power supply. The data collected are shown below.

The table shows the voltage variation based on the utilization voltage of the hospital equipment as well as the values for the voltage unbalance and voltage harmonics of the power supply. The data clearly shows that the quality of the voltage supply is within the operating parameters of the diagnostic or any other electronic equipment of the plus or minus 10% of the rated voltage and should not cause any problems for the equipment.

However, one most probable cause of the equipment’s problem was recorded and is seen at the graph below:

Minimum MaximumAverage


The equipment draws current up to 150 amperes; the normal operating current of the equipment is only 40 amperes. The data prompted another round of interviews with the hospital personnel. The interviews confirmed the findings of the Power Quality engineers – the most common part of the hospital equipment that failed was the power supply fuse. The next component most likely to fail was the equipment’s power supply board, particularly the board’s inverters.

The data shows that inrush current during the equipment’s operation reaches levels that is almost 3 times the equipment’s normal operating current. The equipment’s line conditioning devices – UPS and TVSS – are not capable of mitigating the effects of inrush current.

Solution

Inrush current is a normal phenomena observed during the starting of induction motors. Electronic devices exhibit similar characteristics; when the power supply inverters conduct electricity, the inverters are virtually short circuited and cause a large amount of current to pass through them. This is the inrush current that eventually damages the components over time.

Technical Feature

A reactor is simply a coiled wire that allows a magnetic field to form around the coil when current flows through it. It resists sudden changes in current, the way a capacitor resists sudden changes in voltage. A line reactor is simply a reactor placed in the supply side of the equipment. Any sudden change in current flow will be by the reactor. This is the inherent characteristics of an inductor.

It was recommended that a line reactor be placed between the UPS and the equipment; the UPS will compensate for the voltage drop caused by the reactor installation.

To ensure compatibility, the equipment manufacturer was contacted and no objections were raised to the installation of a reactor between the equipment and the power supply. After installation,

The inrush current was reduced from a high of 150 amperes to less than 65 amperes. This means that there is less current passing through the equipment, reducing the damaging events to it.

If further proof is needed, the equipment was able to function for more than 3 years without experiencing failure. The hospital was able to fully utilize their diagnostic equipment as well as reduce their maintenance costs.

CONCLUSION

Electronics and motors both experience current inrush during their start-up. However, the solution for both cases is different – reduced voltage starters for motors and line reactors for electronics. Power quality data and correct analysis are needed to find

the right solution to any power quality problem; without the proper combination, foreseen solutions may not address the power quality issues involved.

another week of power quality monitoring was done. The results are striking:

A CLOSER LOOK AT POWER FACTOR ADJUSTMENTDOES NGCP REALLY NEED TO GET RID OF IT?

Roque F. Corpuz & Gerald R. Pagobo, MSEENational Grid Corporation of the Philippines

Power factor is the “factor” that is multiplied to the apparent power (MVA) to get the real power (MW). In mathematicalterms:

So power factor is the cosine of the angle between the apparent power and the real power.

2 Rationale, why does NGCP charge Power Factor Adjustment?With reference to Figure 2, each power value in the power triangle corresponds to a value of current. Thus a “current triangle” could be drawn. Figure 3 shows the current corresponding to each type of power.

Why does NGCP charge Power Factor Adjustment? The answer to that question can be found in Figure 3. Recall that NGCP’s power bill to its customers is based on MW or demand. Thus it is charging its customers payment for wheeling energy corresponding to I

MW of

It can be seen from equation (2) that “real current” IMW is increased to 1MW when power factor (or cos θ ) is considered. cos θ

current. Note from Figure 3 that the actual current that passed through the line was IMVA which is greater than IMW . Thus to compensate for the extra current due to MVAR which passed though the transmission lines, Power Factor Adjustment is collected.

3 The Origin of Power Factor Adjustment Formula

Since Power Factor Adjustment is intended to compensate for the extra current passing through the transmission lines, its quantity should be proportional to IMVA. From theequation above.

With more motor loads connected to the system, more reactive power (MVAR) is needed. The net effect is an increase in angle θ and consequently, the MVA is increased. The figure below shows increasing angle θ as MVAR is increased. Note that as θ increases, cos θ or the power factor decreases. Low power factor degrades the quality of transmission line performance.

Thus the Power Factor Adjustment Charge should be based on the Total Demand Related Charge (TDRC) which is the amount charged for

This study investigates Power Factor Adjustment as implemented by NGCP. It looks into the details of its formulation and concludes if it is profitable for NGCP to remove or carry on power factor adjustment.

1 IntroductionWhat is power factor? In a power system, two types of power are actually transmitted. The first is the real power measured in MW and the second is the reactive power measured in MVAR. Ordinary loads such as heaters and incandescent bulbs consume real power (MW). Motors and transformers require reactive power (MVAR) in addition toMW. The vector sum of MW and MVAR is called apparent power measured in MVA. The relationship between the three power values is shown below:

PFA since it considered the factor ( 1 - 1 ). The introduction of SPF in the numerator ensures that the customer is not penalized for having a power factor equivalent to SPF2. The inclusion of SPF in ( 1 - 1 ) however, would result in collecting penalty charges which is lower than the required theoretical charge givenby ( 1 - 1 ). For all practical purposes however the collected penalty charge with SPF as a factor is acceptable as shown in the graph below. Notice that at power factor 70%-90% 3, the curves are almost equal.

Also notice that the deviation of the modified adjustment equation is most evident on lower power factors from 50% and below. This however should not be of concern since for most practical application; power

Adjustment = 3% for bonus (that is pf > SPF) and 6% for penalty. Note that Tacoma and Coon does not award bonus and that their SPF is quite high at 90% and 95% respectively as opposed to Meralco where SPF = 0.85. At higher power factor, which is the usual case in the operation of power system, (pf-SPF) approximates as shown in Figure 6 below.

wheeling energy corresponding to IMW current multiplied by a factorof ( 1 - 1 ). As the power factor increases from 0 to 1, the “factor” abruptly decreases as shown in the Figure below.

4 Legal basis of Power Factor Adjustment Except for the OATS Rules 6 setting the required load power factor of customers to 85%, there are no other references or any other legal basis of Power Factor Adjustment both bonus and penalty. Even the Transmission Development Plan 2007 acknowledges this when it stated:

2 If pf of customer = SPF, = (1-1) = 0 therefore customer isnot charged3 Typical power factor of induction motors.

5 RecommendationsSince NGCP billing is demand based, there is a need to impose the Power Factor Adjustment (penalty) to compensate for the extra current due to MVAR. This MVAR current equally degrades our lines as the MW current.

It is sensible to consider removal of bonus for high power factors since the OATS Rules had already required the customers to maintain a minimum of 0.85 power factor. This means that along with the OATS Rules’ requirement for the customers, it requires NGCP to maintain its line

capacity at customers’ power factor of 0.85.

If investment on additional capacity would be more economical than the cost of the power factor bonus rewarded, then at some point we can consider keeping the power factor bonus.

In general however, as with other utilities, NGCP lines are designed and built to be capable of handling currents at customer standard power factor of 0.85, hence, power factor bonus should be removed and NGCP should get rid of it. Lastly, considerations should be made to increase the 0.85 power factor required by the OATS Rules in view of the practices of utilities in other parts of the world which sets their standard power factor higher than 0.90.
