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)
