Transformer secondary side neutral is earthed.if unbalanced load condition residual return current only goes to earth it's a safest one actually.In basic ground is the very low impedance path compare to your earth rod.current always choose low resistive path.so it's not possible to return feed current flow from ground to equipment.

can we find the inductance of a induction motor?
