how can we check the earth resistance
Answers were Sorted based on User's Feedback
By earth resistance tester that consist of 2 electrodes
along with its leads.Connect one lead from earthpit to
tester & burry 2 electrodes in earth & connect there
respective lead with tester & then check the earth R. It
should be from 0 to 1 Ohm.

Answer / raghavendran.r
The Above stated answer is true but I would like to add
more to that.there is a technique called as Werner
Configuration Technique where we have in total 4
electrodes.The first and fourth electrode is connected to
Current source and 2nd and 3rd electrode is connected to
voltage source and all 4 are inserted into the earth.And
the data is recorded by a Earth resistivity meter.

Why the substation measure in KV but not in the power ratings of transformer.
In a 3 phase squirrel cage induction motor why does rotor rotate? will 3 phase transformer rotate like a motor if it is placed on bearings and powered up? give reason
What is the effect on power factor, shown by a trivector meter; incase of reverse phase sequence. If the power factor of a system is lag what meter will show in case of reverse phase sequence connected to the meter. and What in case of lead.
