ITS because of improper earthing.proper earthig to be
done.minimum voltage is 6v

Answer / s c budhiraja

It due to unbalace loads in the three phases.The limitof
voltage between earth and neutral is 2 volts for computers
to work properly.

Answer / saleem

It due to unbalace loads in the three phases.The limitof
voltage between earth and neutral is 2 volts.

To minimize the volt b/n neutral and earth we have to

In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.
