Answer / 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

Answer / samdipth
i think the difference will be between 1 to 3 volts.....and
the answer no 9 please let me know how come the equipments
will get damage if the difference will be above 3 volts?

Answer / muhammad khalid
earth to neutral voltage 0.1 to 0.9v.
100% perfect earth system.
any question plz call 03343262442

Answer / gopinath
Pahse to Neutral 230vac
Neutral to erarthing 0 to max 3vac
Earthing to phase 230vac

Answer / devendra kumar
440 volt three phase system
line to line 398.36 volt
phase to neutral voltage 230 volt
phase to earth voltage 230 volt
earth to neutral voltage 0 volt in single earthing without joints
and with joints Neutral-Earth= 0 to 5 volts
| Is This Answer Correct ? | 9 Yes | 0 No |
Answer / chandrakant rewatkar
min voltage is Zero ( if no joints)
max voltage is 3 volt ( if there is the joints)
if these value get in case of 3phase supply with P and N
if supply voltage is 415 without variation in voltage.
if value is more than 3 volts,
then load is unbalanced
Earthing not perfect
neutral not proper from incoming supply

Answer / shailesh singh
the voltagr between neutral and earth should lies between 0
to 5 vlts depending upon earthing arrangement.
| Is This Answer Correct ? | 11 Yes | 4 No |
Answer / prasad das
The voltage differance between neutral and earth
will be zero,if it is perfectly earthed.
