What is the neutral point earthing and its advantages?

1 Answer

Answer :

In substation all the neutrals of rotating machines, transformers, busbars and other equipment are connected to ground. Some of the advantages are:
Earth fault protection is based on the method of neutral grounding
The system voltage during earth faults depends on the neutral grounding. During line to ground faults, grounding of neutral helps to reduce the over-voltages which occur on the one healthy phases
