Answer Posted / deb
-Neutral-earth-0 volts(max. 5 volt)
-if Neutral-earth-1 volts, means perfect earthing(in a
office where load present.
At this condition neutral-phase voltage will bw higher than
earth-phase voltage. because leakage current pass through
neutral.
Normally neutral-phase voltage-220 +-10 and earth-phase
voltage same at no load condition(earthing 0 volt)
means if earthing in a office where equipment is running
and earthing voltage suppose 2 volt . the neutral-phase
voltage should be suppose to 220 volt and Earth-phase
voltage 218(neutral to phase voltage 220 volt-earth to
neutral voltage 2 volt = 218 volt).
Please currect me if i wrong
