MBS AG

About ourselves

The Zhleranstalt Rudolf Khler (ZARK), founded in the year 1925, was instrumental in theinauguration during 1977 through Wolfgang Gilgen, managing director and owner, in the todaysvery successful organization MBS Sulzbach Messwandler GmbH.

Further business involvement and investments follow at home and abroad.

1977

MBS is located in Baden-Wrttemberg, in thevicinity of Stuttgart. The organization is knownvery soon for the superior performance of itsproducts, its great innovative strength, and thecontinuous growth of the business. MBS produ-ces initially only a limited number of currenttransformers. Measuring performances, innovati-ons, and maximal product reliability lead in ashort time to obtain a greater, and growing shareof the market.

1985

Since 1985 MBS represents Staatlich anerkann-te Prfstelle fr Messgerte fr Elektrizitt EA90(a state registered testing office for measuringinstruments for electricity). This acculate was onlybestowed on MBS for their continued optimalperformance on measuring realibility and userfriendly safety of their products.

1987

The first works in Sulzbach-Laufen soon reachesits capacity limit due to the marketingsuccess, increasing sales and an ever expandingproduct range. MBS is compelled to enlarge theirproduction and storage facilities. A second worksis created which is adapted to cater for furthereventualities.



MBS AG

1997

The worldwide activites of MBS Sulzbach Mess-wandler GmbH are a challenge for the companyadministration. An architecturally challenging aswell as highly functional multipurpose building iscompleted in the Eisbachstrae 51. Today we findhere the headquarters of the MBS group of com-panies.

Production and warehouse facilities are not con-fined just to Sulzbach-Laufen, but also extend toa neighbouring town. In Slovenia MBS MT is bornto produce the cores for our current transformers.

1995

MBS receives the quality certificate DIN ENISO 9001 issued by TV Mannheim. Thisdistinction opens the door for the worldwideactivities. Already in this year MBS is exportingto more than 20 countries.

1998

We are certified by the GL Germanischer LloydGL Type Approval Certificate.

2000

MBS views the future optimistically and will con-sider at all times the implementation of newchallenges. A fully automated production line formetal and synthetic materials is installed. Due tothe constant growth in the demand for measuringtransducers only the best state-of-the-art uptechnology is aquired and implemented.

2005

MBS again increase their turnover. More andmore customers believe in the product andacknowledge the high quality and professionalismof MBS.

A subsidiary is established in North Rhine-Westphalia, as well as offices in London MBSSulzbach Messwandler Limited and in SloveniaMBS-CT d.o.o..

2004

The expansion of the product range as well asthe custom made units contribute further to thesales successes.

To satisfy the demands of our customers, it isnecessary to increase the production capacity.At the same time, costs in manufacturing had tobe reduced. With these tasks in mind a newmodern storage and logistic center is introducedat the main factory in Sulzbach-Laufen.



MBS AG

2007

MBS AG is born.

A subsidiary is established in northern Germanyto serve northern Europe.

Very senior engineers are employed in manage-ment to meet the ever increasing work load.

At our three production centres, situated in theFederal Republic of Germany, on an area span-ning more than 12.000 m2, 4.700 transformersMade in Europe are being built, in multi-shiftoperation, locally to 100 % in Baden-Wrttemberg.

More than 20.000 products are supplied to allcontinents.

2006

A further expansion is being implemented for themechanical production of synthetic materials andenlargement of the product range.

Another two-storey building is purchased com-plete with offices and facilities for the productionof cores for the current transformers. This manu-facturing site is equipped with machinery for steelband cutting of all sizes, core winding machines,core heating furnaces as well as overhead mobilecranes for transporting heavy loads.



MBS AG

Our expectations for the future

Realizing today, on what others think only tomor-row is our motto. More engagement, more servi-ce, and more customer satisfaction, are at alltimes the goals of MBS.

The management and all employees are highlymotivated, as well as customer oriented, andknow the importance of service, quality respon-ses, innovation and assisting the customer byproviding the shortest delivery times wheneverpossible. This can only be achieved by means ofhand-in-glove cooperation between the variousdepartments. These efforts are clearly reflected inour customers in the home and export marketsas well as our continuously growing customerbase consisting of well-known international orga-nizations covering industry and energy supplycompanies. We are proud of the results of ourhands-on activities. However, the past whilst veryencouraging is now consigned to history.

An extremely long list of orders making full use ofour production capacity, ensures that we can lookinto a successful future.

We expect an increase in customers as well asdistributors. We have to be prepared and notlose-out at what we have created.

The foundation is in place and improvements arebeggin. The tools for refinements are in place. Animportant focus is to keep our administrativestaff fully informed of up-to-date computer tech-nology, which is only one of many tasks.

Low voltage current transformers for tariff applications

Bushing type current transformers

With low measuring currents up toapproximately 50 A it is possible to use asingle-phase plug-in current transformerinstead of the normally used woundcurrent transformer. The prerequisite ofcourse is, that the primary nominal currentof the current transformer corresponds toan integral multiple of the measuringcurrents. The primary winding will in thiscase be threaded once or repeatedlythrough the primary conductor opening.

MBS AG

Current transformers are special transformers for the proportional transformation of high currents into directlymeasurable values. Their construction and physical operating principle enables a galvanic separation of theprimary circuit from the measured circuit, thereby providing a protection for sequentially connected instruments in the event of a fault.

is the noted specified value of the primary and secondary current on the rating plate.Standardized primary nominal currents have the following values: 5 A, 10 A, 15 A, 20 A, 25 A, 30 A, 40 A, 50 A, 60 A, 75 A, 100 A with a decadic multiple of the previously mentioned value toa max. of 7500 A. Standardized secondary nominal currents have the values 5 A and 1 A.

the value of the apparent power (in a VA specified power factor), which the current trans-former is intended to supply to the secondary circuit and rated burden at the rated second-ary current.

according to VDE 0141, section 5.3.4., current- and voltage transformers have to be earthed,starting from Um = 3.6 kV. With low voltage (up to Um 1.2 kV) no earthing is required, as longas the transformer housings have no visible exposed metal surfaces.

signifies the phase shift of the primary current and the secondary current. The direction ofthe indicator is arranged in such a way, that with an optimum produced current transformerthe phase displacement error is equal to zero (IEV 321-01-23 modified).The phase displacement error is to be regarded as positive when the indicator of thesecondary current is ahead compared to the indicator of the primary current. The phasedisplacement error is specified in minutes or hundredths of a radiant. Note: Strictly speakingthis definition is only valid for sinus type currents.

is the effective value in stationary position, and the difference between: a) the momentary value of the primary current andb) the momentary value of the measuring transmission of the multiplied actual secondarycurrent, whereby the positive indicators of the primary and secondary current correspond tothe accord for the connection denotation. The total deviation F1 is generally rendered inthe percentages of the effective value of the primary current, as per the following mathe-matical equation.

F I = total measuring deviation in % iP = momentary value of the primary currentKN = rated measuring transmission iS = momentary value of the secondary currentIP = effective value of the primary current T = duration of period

this denotes the highest constant permitted value for phase to phase voltage for which thecurrent transformers isolation is rated.

Important:

Current transformers, which are not directly encumbered with a burden, are generally sec-ondarily short circuited. A secondary open current transformer operates like a loaded onewith an almost infinitely high burden. The curve shape of the secondary current is extremelydeformed and under certain conditions voltage surges occur which can be harmful to humanbeings. The amount of the induced loss motion depends on the core cross-section and thenumber of secondary turns. For MBS current transformers of lower ratings and with a nomi-nal transmission ratio up to 500/5, the peak value of this voltage is 200 V. For reasons ofhazard protection and to prevent magnetization of the iron core, an open secondary circuit isto be avoided.

The openings of our individual plug-in transformers for the acceptance of primary bus barsor their cross-sections even when supplied with copper bus bars are not decisive forthe dimensioning of the bus bar units. The cross section of the bus bar is permitted to besmaller over a short distance in the transformer area, provided the adjacent bus bar crosssections are dimensioned in such a manner that any possible excess heat can easily beabsorbed.

is the percentage deviation of the nominal transmission multiplied by the secondary currentfrom that of the primary current. The current error is calculated positively, should the actualvalue of the secondary current exceed the nominal value.

F I = current error in % I S = secondary current in A (effective value)IP = primary current in A (effective value) KN = rated measuring ratio

is the primary current which allows the continuous operation of the current transformer.When using this current value, the temperature of the secondary wiring must not exceed theprescribed values mentioned in the actual technical norms. These values are in direct rela-tion to the isolation material class. Should a thermal rated current be defined which is largerthan the primary rated current, the preference values of 120 %, 150 % and 200 % shouldreflect those of the primary rated current.

This value indicates the effective value of the primary current which the current transformerscan withstand with short circuited secondary winding. Other rated measuring values as 1s, e.g. 0.5s, 2s and 3s are acceptable. The thermal shorttime rated current Ith has to be stated for each current transformer.

is the ratio of the limit rated current to the primary rated current. Note 1: It ought to be noted that the actual over-load rated current is influenced by theburden.Note 2: Should the primary winding of the current transformer be short-circuited, the safetyis greatest, when the value of the over-load current limit factor FS is small.The excess current limiting factor is indicated on the rating plate of a measuring transformerwith a nominal value after the letters FS.

The specification FS 5 signifies that the total measurement deviation of the current trans-former with 5 times the primary nominal current arising from the magnetic saturation of theiron core amounts at least at to 10 %.

All MBS current transformers are in accordance with DIN EN 60044/1 for a thermal nominalcurrent of I d = 1.0 x IN.

Power requirements of measuring units and relays

Two main requirements are cited by the user for the principle demands of current transformers:

a high degree of measuring precission in the range of nominal current a protection function in the over-load range

In order to fulfill these demands it is necessary for the assumed nominal power of a current transformer to fullyachieve the actual power requirements of the prescribed measurements.In ascertaining the actual power requirements, consideration is to be given to power losses of the appliances to beconnected, as well as to the losses of the measuring conductor.
