Trf will fail as the un-balanced current will enter in the main windings.

Answer / arup kumar sadhu

Neutral is grounded to protect against earth faults and to eliminate transient voltages. If not earthed we would never know that a conductor has fallen down and during this if another conductor falls down ,the fault current will be 73.2 % more.With one conductor fallen on ground the voltage between healthy conductor and the ground will be 1.732 times the normal

Why only plate(copper) Earth pit given for neutral earthing? why not pipe(G.I) Earth pit?
