Ans.First you have to find out the full load current of the
transformer that is IL=2915A then as per NEC you have to
give atleast 25% that is 2915x1.25=3643.75A.So the nearest
size of Circuit Breaker shall be 4000A.

Practical condition in 400KV Sub station:- Breaker(open) , isolator(open), Earthing (close) at both end e.g A & B. Now Open A Stn Earthing than Open B stn Earthing (Which have a 50MVA reactor) , AND suddenly show R,Y,B phase 704KV,573KV,118KV respectively. Que is without closing of breaker how it is possible.????
