Question

What is the value of earth resistance?

Answer 1

The value of earth resistance is less than $5$ ohms. i.e 0.5 ohm

Explanation:

1. The maximum earth resistance value is set as $5$ Ohms.
2. Please keep in mind that this is the value of earth system resistance, which is the total resistance of all earth electrodes in the installation connected by an earth grid wire.
3. The soil resistivity values are dependent on the soil type, as evidenced by soil identifications, earthing, and extensive field measurements.
