First measurethe line voltage with respect to earth and
neutral separately and check which one is lower.
Case -1 If Ground to line voltage is lower then fault is
with ground ie earhing. It can be rectified by
strengthening the earthing or by making separate earth pit.
Case-2 If Neutral to line voltage is low then problem is
with your neutral line such case is to be dealt separately
as mentioneb below
a) either put isolation transformer in the circuit and
ground one terminal.
b) Make separate earth pit for the neutral line
c) check the main neutral connection ans size of the
neutral wire
