To grounding the neutral of a transformer becease this time
neutral is works as earthing. And the earthing safety they
transformer by any kinds of electrical falts. over load
current & lighting.

Answer / bhavesh patel

grounding of neutral is because of whenever there is fault in equipment, the excessive current flow through in it and it will ground through neutral wire

Answer / simon peter

In distribution transformer the secondary side is always in star connection i,.e a neutal piont is drawn. Neutal wire & the core of x-mer is connected to earthing bcs if there is enormous load variation the overall load will b on phase wires hense x-mer might blow off due to increase in the value of hysteresis & eddy losses........

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.???? My Whats app No:07621840498 for Further Discussion. Pls experts suggest.
