Do you know how to measure the earth resistance? if so explain it..

Answer / dinesh. r

Actually the Earth resistance is measured using "earth
resistance meter". In previous answers some said that using
megger, but megger is used only for high resistance
measurement i.e., in Megaohms but when considereing upon
earth resistance it should not exceed 1ohm so earth
resistance meter is required.

In this meter there will be four terminals(E, P1, P2, P3)
in which E and P1 will be shorted and connected to the grid
or electrode and P2 and P3 are reference electrodes which
will be kept on the earth surface on two different
locations for taking the reference resistances of the earth.

The meter shows the resistance of the earth. But it is
neccessary that it should be below 1ohm.

Answer / dinesh kumar

1.To measure earth resistance we use Earth Resistance
Meter/Megger.
2.In this Megger there are three terminals
Line,Nuetral&Earth.
3.Line & Nuetral are connected to two terminals and EARTH
Terminal to earth pit to be measured for resistance.

Answer / ullas

using two methods:
1.fall of potential method
2.earth tester(device)

factors affecting earth resistance are
1. Shape & material of the earth electrode.
2. Depth of the electrode at which they r burried in soil.
3. Specific resistance of the soil surrounding the electrode

(Specific resistance of the soil varies depending on
moisture content in the soil..... varies from 80*10^3ohm-m
to 80*10^6ohm-m)
