What is min and max voltage between earth and neutral/phase
if it perfect earthing?
Answer Posted / pradeep
Regarding answer 11, i think in case the Neutral to Earth
voltage is high, it means there is an unbalanced load in
the three phases (in case of 3 phase supply) or the neutral
is not proper. Either way, there is a chance of current
flowing back into the circuit because of improper neutral
or earth not properly grounded, resulting in equipment burn-
outs in case of a surge. These equipments need not be
switched on and will burn-out in case of fault. Thus it is
recommended to keep the voltage between Neutral and earth
as low as possible.
