In view of lead time available before commercialisation, POWERGRID embarked upon the idea of developing a 1200 kV test station along with a short 1200 kV transmission line on Public Private Partnership (PPP) model.
TARIL is contributing a 333 MVA, 1150/400/33 kV 1 phase transformer to this Mega Project, which has been successfully developed with in-house R&D efforts.
First phase comprising 3 single phase autotransformers, forming a bank of 1000 MVA, 1150/400/33 kV has already been commissioned on no load. TARIL transformer shall form part of Phase II bank of the 1200 kV test station and shall be used for loading the transformers of Phase I on 400 kV side.
The transformer weighing 190 tonnes was loaded on a special 14- axle hydraulic trailor, on its way to Bina covering a distance of over 1600 km.
