Question

Principle of earthing ,types of earthing and earthing process

Answer 1

earthing systemor grounding system connects specific parts of that installation with the Earth's conductive surface for safety and functional purposes. The point of reference is the Earth's conductive surface

There are five types of neutral earthing:

Solid-earthed neutral.
Unearth
ed neutral.
Resistance-earthed neutral. Low-resistance earthing. High-resistance earthing.
Reactance-earthed neutral.
Using earthing transformers (such as the Zigzag transformer)

Answer 2

Answer:

At the time of the fault, the earth mat conductors rise to the voltage which is equal to the resistance of the earth mat multiplied by a ground fault. The contacting assembly is called earthing. The metallic conductors connecting the parts of the installation with the earthing are called electrical connection.
