What is min and max voltage between earth and neutral/phase
if it perfect earthing?

Answer Posted / k s yadav

Regarding Q11, whenever get more voltage across neutral and
earth that will imbalance the phase voltage with respect to
neutral as well as phase also cause conneted load or
sensitive devices might be got faulty or do the wrong
operation as per induction theory.Therefore earth leakage
voltage should be zero in ideal condition but in practicle
should be maintained less than 1 voltage in organisation.

we have an energy meter in a capacitor bank panel, So should we consider it's readings as energy consumption on daily basis. (when capacitor bank doesn't have any energy losses)
