Transmission line design. Say, I have a 1MVA generator and 2 transformers that will have the same load. What would be the proper rating of the trasformers? Is it safe to say, that I will simply divide the total rating of the generator?

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.????
