Answer / raveendra nath
normally Voltage Transformers are designed on the basis of
insulation grading to minimise the cost.
(i.e Voltage level decreses towards neutral, So while
designing, Insulation level will decrease when going
towards neutral )
So, transformer nuetral must be at earth to keep it at zero
potential and to avoid any flashover under fault conditions.

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.????
