Equipment Earthing
1.
2. When the non current carrying metallic parts of the electrical equipment are connected to earth through a very low resistive path, it is called as equipment earthing.
3. It provides protection to living beings (animals/humans) against electric shocks.
4. Does affect stability of the power system in any way.
5. Equipment earthing is provided through Pipe earthing, Plate earthing or earth mats etc.
6. It provides protection to the living beings and also can help protective system to protect the system equipment against earth faults.
Neutral Earthing
1.
2. When neutral of three phase star connected winding of transformers, generators, motors is connected to earth, it is called as neutral earthing.
3. Provides elimination of arching grounds and over voltage surges.
4. Stability of the power system is increased.
5. Neutral earthing is provided through solid earthing, Resistance earthing, reactance earthing.
6. It provides suitable means for earth fault protection of equipment.
