Answer / mf.khan

Transformer size can be calculated on Maximum Dammand Load.

For 122KV MV Switchgear fault level should be 350MVA.

Answer / ravindra

Transformer rating calculated in KVA. We can measure any
transformer rating from its HT & LT Bushing.

Transformer cores are laminated in order to A simplify its construction B minimize eddy current loss C reduce cost D reduce hysterisis loss
