It is seen that despite best efforts by many electricity boards / supply undertakings, due to diverse loading duties arising in transmission and distribution network, voltage at consumer's end is never constant. This low/high voltage is applied to all electrical machines like Transformers, Motors, etc., hence causing loss in substantial electrical energy. Besides voltage fluctuations also play havoc by damaging expensive, sophisticated, CNC/PLC controlled equipment, lighting, elevators, etc. Therefore arising a need to conserve energy as power tariff is ever increasing. We manufacture HT-AVR that are designed to overcome & control voltage fluctuations due to diverse loading duties & line losses arising in transmission & distribution network. These are designed for balanced as well as unbalanced loads & input voltage supplies. HT-AVR operates ON Load directly on the HT line and provides a stabilized HT output voltage +/-1% that is fed to the step down transformer resulting in constant/stable LT output.

We offer Panels with diverse specification options for a highly customzed panels upto 6300 amps having fixed and draw out types, including single/double front type. The LT Panels conform to IS 8623-part 1:1993 & IEC 439-1:1985.   Our panels are designed to withstand high humidity, temperature, ambient service conditions and short circuits levels & these make our panels an ideal choice. Our panels provides superior control & protection of low voltage power equipment & circuits in utility, industrial, commercial installations involving generators, motors, feeder circuits and distribution.   An electrical distribution board that receives power from generator or transformer and distributes the same to various electronic devices and distribution boards. Such panels are used in industries both for internal and external use and therewfore are quite rugged to withsatnd different climatic conditions. Our LT Panels are designed to work with low electricity consumption that makes them cost effective.   These panels work between two or more different power sources like DG sets to manage power supply. Synchronization helps in making different DG sets behave as a virtual single unit and eliminates sub-division of total load. It helps in transferring loas from one unit to another as during service period, so that the unit requiring service can be easily shut off. In this way the critical load need not be interrupted and there is no production loss. During low load we can run any single unit and synchronize more units as the load increases automatically.   Features     Fully compartmentalized design Easy to install, operate & require very less maintenance Cost Effective & Space Saving A high degree of Safety & operational reliability is achieved Tailored Configuration to meet client's requirements Aesthetically enhanced look & designed to suit client's requirement Designed to meet temperature rise limits Safety   Completely enclosed bus bar chambers Shrouded links in feeder compartments Dust & vermin proof construction Bus bar constructions to withstand high fault levels upto 70 KA

We manufacture Cast-Resin Dry Type Transformers upto 3000 KVA; 33KV class as per Indian & International Standards i.e. IS, IEC & ANSI etc. Our transformers are design to withstand high humidity, temperature, adverse service conditions & short circuit levels & all these make our products an ideal choice. Designing, selection of raw materials, state of the art – Casting Plant, in house testing facility & highly experienced manpower make our products very reliable & cost competitive. Maintenance Free Due to encapsulation of coils with cast resin the coils dimensions are stable & no coil tightening is required to maintain the short circuit strength. Also no check of oil level and electrical insulation/oil is required. Non- Hygroscopic In cast-resin dry-type transformers, the complete encapsulation of primary and secondary winding in epoxy resin prevents penetration of moisture into windings. The cast resin offers very good protection against adverse ambient conditions. These transformers can work without disruption of service at 100% humidity. Non Inflammable and Self Extinguishing Due to high quality insulation material the transformer is practically non-inflammable by an electrical arc, special fire protection measures are not required. Resistant against Temperature Fluctuation The insulation material used is glass fibre reinforced with epoxy resin of class 'F' which can withstand wide temperature variation. Higher Impulse Strength Contrary to the conventional dry type transformers the cast coil transformers are better in respect of impulse voltage withstand strength. Higher Short Circuit Strength Higher dynamic short circuit withstand strength as compared to oil immersed and conventional dry type transformers because of fibre glass reinforced epoxy encapsulation. Free of Partial Discharges No partial discharges can occur during operation. Instant Switching Due to the high grade insulation material, coils are non hygroscopes & the transformer can be switched on directly without pre-drying even after a long period of service interruption. No Leakage or Pilferage of Oil As cast resin transformers are solidly cast, problem associated with oil filled transformers like oil leakage and pilferage of oil is completely avoided. Saving in Space These transformers are generally smaller in dimensions and lesser in weights. The construction and installation cost for the sub-station can be reduced by adopting dry type transformers. Eco-Friendly Since no oil is used in these transformers, there are no chances of contamination of ground water due to oil leakage. Saving in Civil work cost and LT cables Without fire or danger of explosion, it is possible to place the transformers near to the load centre. Also, these transformers do not need construction of special fibre brick walls or oil pits, which reduces the overall civil works. Additionally, since LT cables are not required, thers is also saving in cost on account of expensive cable laying works.     Public Places and High rise buildings Shopping Malls Railway Fixed traction installation Underground Cranes Seaports and Offshore platforms Drives Gas , Turbines , Generators and Drilling system Solar Application Mining Ranging up to 3000 KVA Capacity Up to 33 KV Class Three-Phase, 50 / 60 Hz Single / Dual Ratio Naturally Cooled (AN) or Forced Air Cooled (ANAF) Sheet metal enclosure with vents for air circulation IP-23 or as per customer's requirement Accessories / Fittings as desired by customer Insulation Class F / H, others on request Applicable Standards IS:11171, IEC:60726 Tap Changer: Tap Links / On Load Tap Changer (OLTC) with RTCC & AVR Temperature Sensors for alarm and trip protections
