BHEl Bhopal designed and manufactured highest rating special type split winding 120 MVA 400/11.5-11.5 kV Station Transformer for prestigious 2x800 MWNTPC lARA STPP (CG) project is successfully Short Circuit tested at National High Power Test laboratory (NHPTl) Bina (MP).
Significantly, this is the highest rating 400 kV Station Transformer short circuit tested for the first time in the country from live line i.e. directly from Transmission grid. Short circuit test is most stringent test for Power Transformers to prove its adequacy to withstand abnormal conditions of short circuit and its reliability during its operation.
This is the 15th 400 kV class Transformer of BHEl which has passed short circuit test till date.
Split winding Transformer is a special type Transformer in which lV winding is split into two parts with a common HV winding. These compact size Transformers are exclusively used in large thermal power station to feed power to motors, fans and other station auxiliaries to run the thermal power plant.
BHEl is the largest manufacturer of Power Transformers in India and pioneer in indigenous development of higher rating and specialized type Transformers upto 1200 kV class. BHEl Bhopal’s Transformer Plant has ‘state of the art’ world class manufacturing facility commensurate with global practices and fully equipped to fulfill the expectations of Utilities in the entire range of Power Transformers and Shunt Reactors.
