Distribution Transformers

Three Phase Distribution Transformers: Tesla has setuped a complete Quality Management System (QMS) to offer the highest customer satisfaction. Maintaining quality in engineering, manufacturing, sales and services is of the highest priority for Tesla. The Tesla Quality Program (TQP) is based on the philosophy of prevention and not just on the detection and correction of problems after they occur. Tesla is equipped to manufacture transformers with a wide range of internationally recognized standards such as: IEC (International Electro Technical Commission) s ANSI (American National Standard Institution) s BS (British s Standards) IS (Indian s Standards) ESCOM Standards s SESCO Standards s AS Standards s

Tesla manufactures wide range of distribution and power transformers ranging from 25 KVA to 63 MVA with voltage class of 132 KV maximum. These transformers can be free breathing type, fitted with a conservator or hermetically sealed. The liquid filled range can be cooled by either tank mounted plate radiators or by corrugations on the side of their tank. Free breathing units with or without conservators are normally oil filled while hermetically sealed transformers can be filled either with oil or one of the several low flammable synthetic fluids. Both types can be supplied with HV and LV switchgear, incorporated in to substations. Hermetically sealed transformers are totally maintenance free and are particularly suited for use in exposed outdoor environments such as moisture, salt or dust laden atmospheres. They are used extensively in chemical plants, oil and gas terminals where poor accessibility makes regular maintenance impractical. Transformers immersed in synthetic coolants are suitable for indoors with adequate ventilation near load center where oil would not be considers environmentally acceptable.

Tesla make conventional bolted/sealed type hermetically sealed unitized transformers, dry type indoor & outdoor type, pole/ platform mounted 3 phase, 50/60 Hz, oil immersed, ONAN/ONAF/OFAF cooled, step up /step down double wound with AI/Cu conductor continuous duty transformers from 25 KVA to 63 MVA 132 KV class with 'A' class insulation and designed to withstand Short Circuit and Impulse Test in accordance with IEC/BS/ANSI/IS/NEMA. Tesla products are type tested at Central Power Research Institute (CPRI) an internationally accredited testing laboratory, as per relevant ANSI/IEC/BS/IS standards.

The outgoing feeder will have either cable box or plug & socket arrangement for feeding power to LT equipment.

Setting high Standards as a consistent guarantee of the highest quality the company have achieved ISO 9001 certification for all its transformers. Regular internal and external quality audits ensure full and continuos conformity with the international standards. The company's material and components suppliers are also required to satisfy these ISO standards.

Quality control is earned out at each stage of production on a self-assessment basic. Each employee regards the next workstation as his customer and performs a series of quality checks before passing on a product down the line. The quality development department monitors all quality control documents and carries out its own additional inspection at strategic points in the production process. This system of checks and counter checks allows immediate action to be taken and modification to be made as required. All transformer tanks are tested before being released to the customer. Testing includes leakage test and pressure test.

What prevails at tesla is a continuos urge to stay ahead, preserve, innovate and make a qualitative difference through sincere efforts. It is this overriding commitment that has seen the company mile ahead of others. At Tesla, the distinguishing feature is better and assured quality. A series of stringent quality control tests endow the tesla transformer with operational reliability and long life. The intermediary and final inspection comprise of a large numbers of test in accordance with national & international standards like IS -2026, BS-171, and IEC -76, using precision grade instruments. Test reports are supplied along with the transformers. The vindication of Company's merits is also reflected in it being one of the very few transformer manufacturers in India to have secured ISO 9001 Quality Certification From ANSI-RAB, USA. This internationally acknowledged quality assurance system ensures manufacture and supply of products conforming to specified customer requirements along with continuos improvement in quality & performance. The Company takes extra care to ensure timely delivery once an order is placed and a qualified team of engineers provide efficient after sales services.

Winding Connections

Tapping and phase leads are run in paper-covered conductors, the phase leads being separated from the tapping leads by adequate barriers. These tubes are rigidly brazed to ensure that required clearance from coil to tank is being maintained. L.V. Leads, larger in cross section, are generally sufficient robust, but where necessary supports are provided.

Tank Construction

All tanks are made from mild sheet of adequate thickness with pressed steel fins /cooling tube for heat dissipation. All tanks are checked by magnaflux ultraviolet ray die penetrating system to ensure that there is absolutely no leakage from any part of the tank.

Quality Finish Through Use Of Shot Blasting Technology

Tanks are shot blasted/ Grit blasted to remove mill and welding scale and then a primer coat is immediately applied to the exterior to eliminate rust formation. After priming all tanks receive a coat of intermediate paint, and after pressure testing, they receive a final coat of high gloss paint applied by spray. This ensures high coverage helping to combat corrosion in inaccessible places.

Insulation And Impregnation

The principal component of insulation is insulating Pre-compressed Press Board. The components like rings, duct, dovetailed spacers, blocks etc. are put under compression along with the coil assembly for pre-shrinking. Providing additional insulation compensates the slight recovery in dimensions after the pre-shrinking. This reduces the probability of coils getting loose during operation and also minimizes the failure due to circuit forces.

In order to meet the outgoing demand of transformers with short deliveries in domestic supply. Tesla has developed a Separate production system called TST (Tesla standard Transformers). This range of TST's are manufactured with standard losses and compiling with IS-2026, latest edition. Tesla can supply a comprehensive range as depicted below, in short delivery period.

In Order to prevent deformation under short-circuit forces, solid insulator end blocks and rings are used. Windings are compressed under top and bottom clamping members with the help of tie rods. The axial end thrust under fault condition is minimized by the suitable balance to the ampere-turns over the length of windings. In case of bigger transformers, the HV taping leads are taken out from two positions to balance the short circuit forces in a much better way. At Tesla each and every component used in transformer undergoes a series of stringent checks and controls at each stage of manufacturing and it is ensured that strict technical & qualitative specifications are adhered to. Utmost care is taken while manufacturing and assembling every component of a transformer. The main process line of a transformer is:


The core is constructed from lamination of imported Cold Rolled Grain Oriented (CRGO), low loss electrical steel. The cores are assembled in jigs prior to tapping and clamping in a manner that reduces vibration and inherent varnish, which is both oil and heat resistant and complete core is connected to the clamps to ensure that it is effectively earthen. The core legs are surely bound with heavy duty insulating tape and the yokes are firmly clamped between folded steel channels. Tops & bottoms clamps are secured to each other by means of tie rods which serve the dual purpose of securing the windings in the place and of transferring the load form the bottom to the top clamps when the core and windings are lifted. This prevents any tensile stress being setup in the core legs which could adversely affect the iron losses.


Transformers windings, or Coils are designed to meet three fundamental requirements, mechanical, Thermal & electrical. They are cylindrical in shape and are wound concentrically. Both H.V. & L.V. windings are wounds with adequate brazing and securing tapes in order to achieve a strong and self-supporting structure. Inter layer ducts are provided to ensure low temperature gradient between winding and oil and thus any hot spot temperature is kept to minimum. This insures that the rate of insulation deterioration is minimized and high life expectancy is achieved.
