Question

Name the instrument used to measure the earth's resistance?

Answer 1

Ground resistance meter:

1. Ground resistance meters test soil resistance for the safe passage of electric current to determine the feasibility of the grounding of an electrical system.
2. Hence ensuring a large path for fault currents, is an indispensable component of a safe, properly functioning electrical system.
3. Earth resistance is a very important parameter for calculating the amount of short circuit or leakage current dissipating in the ground.
4. In ideal cases, the ground should have zero ohms resistance.
5. There is not any standard ground resistance value that is recognized by all agencies.
6. However, many agencies worldwide have accepted a ground resistance value of 5.0 ohms or less.

Thus, the Ground resistance meter is an instrument, which is used to measure earth resistance.
