Answer / faiyaz

beetwin earth and neutral r value is 0 ohm

Answer / sunil kumar

if neutral and earth are separated taken then the
resistance should be infinity

Answer / ashok

earth to neutral voltage is maintained 4 volts
for acurate earthing that voltage is below 1 volts

Answer / k.prakashchandra

Minimum earth resistances in ohms for stations-1) 33KV -5
2)66KV-2 3)110 to 400 KV -1 4)Gen stations -0.5

Answer / harbhajan

0 to 3 volt

Answer / abhishek goswami

the stander resistance between the neutral & earth is less
than 1 ohms

Answer / raghu

The Potential difference between earth and neutral is below
4V then it is good earth connected system..

Answer / cnu

actually the parameters between earth and neutral is
measured in terms of VOLTAGE. according to IS the voltage
between nuetral and earth shud be less than 0.8V.

Nuetral is taken from the source while earthing is done
near the device. so to check for a perfect earthing
conditions the above voltage criteria is to be satisfied.

Answer / faheem

zero

Answer / hitesh gohil

If Nuetral is earthed then R velue = infinity
If Nuetral is not earthed then R velue = zero
