PhilosophyTrafoStar is a new concept for the design and manufacture of power transformers.A TrafoStar transformer is built of standardised, service-proven components andmodules, ensuring flexible, dependable and tailor-made transformer designs.

HistoryOver the years, eight major power transformer manufacturers have merged toform ABB (Asea, BBC, GE USA, Westinghouse, Ansaldo, National Industri andStrömberg). TrafoStar utilises the best practices for each and every process, technology and component that this joint know-how and experience offers.

DesignExtensive R&D has generated a set of common electrical and mechanical designrules that each and every TrafoStar transformer follows. This modularised designallows a re-use approach that brings factory throughput time to a minimum withmaximum quality.

ProductionAll production processes and work methods are performed according to set,standardised procedures following the best practices developed at ABB’s 27transformer factories worldwide. Together with state-of-the-art tools and equip-ment, 6-Sigma quality control and well-trained personnel it ensures top qualitymanufacturing.

TestingThe design and manufacturing quality is verified in our world-class labs. All factories use the same, top-quality test equipment, test structure and protocols.The labs also include the latest in diagnostics equipment for accurate interpre-tation of test signals.

Custom designThe TrafoStar concept allows an endless variation of transformer designs – alldesigned and built on well-tested, service-proven modules. For you this meansaffordable and high quality transformers built exactly according to your needs.

ReliabilityModularisation means that each process and piece of equipment that goes intomaking a TrafoStar transformer is tried, tested and verified. Therefore, we canensure you utterly reliable transformer performance.

ProfitabilityTrafoStar offers high reliability with high up-time and low maintenance require-ments. And that translates into low life-cycle costs and high profitability for you.

The winding assembly follows rigorousquality standards. High cleanliness, highquality parts, tight manufacturing toler-ances and constant 6-Sigma measure-ments ensure very low impedance varia-tion.

The ascecond core clamping method is designed to create an even pressure to keepthe core sheets together and give support to the windings. This robust design givesshort-circuit strength and improved transportation safety.

The step-lap method is used to creategood magnetic contact in the core joints.This ensures a low reluctance for themagnetic flux, which translates into lowlosses and low noise.

Continuously transposed conductorsallow smaller dimensions and lower loss-es. For more efficient cooling, net tapingis sometimes used instead of traditionalpaper insulation.

2. Robust design features make all the difference

R O B U S T N E S S F O R R E L I A B I L I T Y

Electrical design rulesContinuous trials and experiments verify the transformers’s short-circuit strength. Theyalso result in extensive design rules and acceptance criteria to evaluate the stresseseach winding design can handle.

Mechanical design rulesABB’s mechanical design rules are built on well-developed calculation methods thatalready on the drawing board allow us to define factors such as noise level, losses andshort-circuit strength.

Core designThe core design is a direct result of each customer’s evaluation of factors such as losses, noise and weight. For demanding applications only top quality laser-scribedsteel is used. All designs utilise step-lap joints and rigid clamping using Ascecond, asemi-conducting tape that both keep the core sheets together and gives the core asmoother, more efficient electrode shape.

Winding designSophisticated calculation methods give proper winding dimensions for optimal electricalstress distribution.Together with extremely tight manufacturing tolerances this ensuresboth mechanical and dielectric stability.

Gasket system for superior tightnessCoolers, bushings, pipes and covers – all need tight, leak-proof gaskets to protect thetransformer and the environment. TrafoStar utilises nitrid rubber gaskets in grooves toensure superior tightness.

Corrosion protectionThe environment friendly corrosion protection system of ABB’s transformers is devel-oped to meet the demands of all climates.

Drying and fillingABB pays particular care to the drying and filling process. Perfect control of the insula-tion paper moisture level ensures efficient electric withstanding capability. During dryingthe windings are subjected to cycles of pressure to make the insulation material settleand to establish the final winding height. Warm oil is then vacuum filled from the bottomof the tank, which makes sure that each and every oil channel is filled.

Skilled craftsmenABB’s assembly personnel go through continuous training and education in areas suchas joining and soldering. Key personnel also do proficiency exams every year wheretheir test parts are cut and X-rayed.

CleanlinessNo electrically conducting particles are allowed to enter the active parts of the trans-former. Therefore, all our factories have special clean areas where sensitive manufactur-ing processes take place.

Production qualityEach production step is operator controlled to ensure the highest quality. Elaboratecontrol procedures and continuous measurements are used to verify the correct result.

ImpedanceAchieving the right impedance is ensured by having all process-es during construction under control. The mechanical tolerancesmust be just right. Modularised and standardised productionmethods and continuous 6-Sigma quality control measurementsmean that our transformers have the impedance they aredesigned for.

LossesAdvanced calculation tools, deep material know-how and tighttolerance manufacturing make sure that the tested losses arevery close to what was originally designed and calculated. Withthe TrafoStar concept ABB has been able to reduce the testresult variances (scatter) to a minimum.

Temperature riseBeing able to calculate the oil flow at all sections of the windingis the key to designing transformers that do not overheat.TrafoStar’s modularised design gives us control over thatprocess. Solid proof is our temperature rise test results that correspond very closely to the designed levels.

3. Accurate testing shows continuously improved quality

StrategyTrafoStar includes a program for continuous improvement. Constant measure-ment and careful statistics about achieved tolerances give important input to new designs and product improvements.

Processes under controlThrough elaborate 6-Sigma measurements of each little production step, weknow that our designs are perfectly put together on the workshop floor.

Low scatterThe design and manufacturing quality is verified during testing. Quite simply, testresults that are close to what was predicted during the design phase indicate thatour processes are under control and that equipment quality is right. And we striveto reduce the test result scatter to an absolute minimum.

Partial discharge freeOne effect of the TrafoStar modularised design is that we can make our trans-formers practically partial discharge free. We make sure that there are no sharpedges, that the conductors are round and smooth, that the insulating material is absolutely dry before filling and that all manufacturing is performed in cleanworkshops.

Hot spots under controlAdvanced calculations, experiments, measurements and statistics help us reducehot spots to a minimum. Thus, we can already at the design phase determinepotential areas with high leakage flux and take appropriate action in the form ofmaterial choice, manufacturing tolerances or even re-design.

Quality auditsABB Power Transformers has developed its own quality system based on contin-uous control and audits of all sub-suppliers. We follow up faults, delays and tech-nical performance in an effort to find even better solutions for the future.

Common research and developmentWe constantly perform joint research and development projects with our partners.By utilising a wide network of specialist’s know-how, ABB, together with key sub-suppliers, develop new, effective and cost-efficient transformer technology.Superconducting materials and new cable technology are cases in point.

High reliabilityA transformer’s reliability depends on the quality that is built into the equipmentthroughout the entire production chain. Therefore, not only our own workshops,but also our subsuppliers are subject to continuous 6-Sigma measurement.Together with the just-in-time deliveries of components and subsystems comes a 6-Sigma protocol to verify the quality control.

Smooth logisticsThe entire production chain must run smoothly. We communicate electronicallywith our partners regarding both technical matters such as drawings and researchprojects as well as for commercial documentation. ABB also uses the partnerknow-how to make kit-deliveries for fast and smooth final assembly.

5. The best short-circuit strength test record

S H O R T- C I R C U I T T E S T I N G

Power transformers are vital components in power transmissions systems and in electrically intensive industries. New patterns of interconnecting power networksand a trend to increase power generation capacity means that the short-circuitduty of power transformers is becoming more and more severe.

Therefore, ABB puts a lot of effort into understanding short-circuit forces andeffects. Indeed, unlike most other manufacturers, our approach is not only theo-retical and restricted to purely statistical considerations of the electromagneticforces. Instead ABB builds its know-how on a large and unique experiencegained from more than 115 short-circuit tests performed on full-scale powertransformers as well as from short-circuit events in the field.

Full scale short-circuit tests include transformers rated from 10 MVA to 775 MVA, which is the largest short circuit tested power transformer in the world. And theyinclude practically all transformer designs and types, from single concentric todouble concentric winding arrangements, and from generator step-units to inter-connecting power transformers.

ABB’s extensive test record and deep know-how means that we can offer youtransformers with the very best short-circuit performance on the market.

ABB Power Transformer’s vision is to be a world-class manufacturer, makingworld class transformers. This vision is quantified according to the 6-Sigmamethodology. Technically, 6-Sigma quality means a quality level allowing less than0.000003 defects per opportunity, i. e. 3 defects per one million opportunities.And 6-Sigma makes good business sense. Our customers appreciate high quality, and for us it costs less to manufacture parts and products rightly from the beginning rather than fix and adjust them later.

Quality is quantifiableTo assess quality, ABB has made a long-term commitment to keep close track of statistics and to use this knowledge to constantly improve processes and solutions. And we don’t rely on old experiences, judgements and beliefs – onlysystematic assembly of hard facts and analyses will do. The ultimate goal is toreduce variances to a minimum.

Steady improvementAll 27 ABB Power Transformer plants worldwide are now involved in the 6-Sigmaquality control program. All employees are informed and educated, and everyprocess is analysed and measured in a program of constant improvement. 6-Sigma also means that it is possible to track quality. Every step in the design,manufacturing and delivery process is checked and signed, which gives goodfeed-back if systematic faults occur.

So far we have seen a multitude of positive short-term results, both in manufac-turing and non-manufacturing processes. One example is the winding height ofcore transformers manufactured at our plant in Córdoba, Spain. In only two yearsthe number of faults has been reduced by 90%.

Other successful 6-Sigma projects are: Measurements on winding conductors forlower variances in loss measurements. Continuous measurements of dimensionsand cooling channels in the windings for lower scatter in temperature measure-ments. Close measurements and analyses of drying processes for better dryingand lower partial discharge in the transformers. Naturally, these processes arenow used by all our transformer factories.

Fast, on-time deliveriesHigh quality throughout the entire production process is a prerequisite for fast and smooth production. 6-Sigma helps us work in a structured and efficient manner, which allows us to promise you short, on-time deliveries – with ABBquality guaranteed.
