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........
