HOW MANY EARTHINGS REQUIRED FOR GENERATER
Answers were Sorted based on User's Feedback
Two eathing are req. minimum. Since the star point is
earthing solidly, and obviously the generator frame/housing
also to be provided with earthing to prevent any shock due
to insulation failiure.
if the generator is connected with a fuel tank, (for higher
size), it is necessary that, fuel tank to be grounted to
prevent lightning surges and any static voltage generations.

Answer / sudheer siddani
depends on the rating of the generator upto 125kVA two
earthings is sufficient one is neutral and one for
body.>125kVA four erthins are required two for neutral and
two for body

Answer / rajeshsan
The earthing of Generator at star point is depends on the capacity.
For larger generators eg:- 600MW generator the generator is grounded using NGT and generator body is grounded at two ends. Earthing are done at two ends to have redundancy only.

Answer / pankaj singh
there should be two earthing required.one for star point
and another for body. At the star point there should be a
solid grounding,on the other hand body frame should be
earth diagonally and the material for grounding depend on
the rated valtage of generator

Answer / ajay kumar das
Normally minimum 4 earthing required .2 for body earth & 2 for neutral,But in case for 11 KV generation another 2 earth is required for L.A.

Answer / bhasker reddy
Depends on the KVA rating of generator earthing are required.
less than 40 kva atlest 2 earthing(one neutral & one body earth). more than 40 KVA 4 earthing (2 neutral & 2 body earth). if KVA rating increased should increase earthing.

Answer / gunasekaran
their are two system earthing at single voltage level in
generation one is generator neutral another one is PT
earthing and body earthing also provided
| Is This Answer Correct ? | 0 Yes | 1 No |
Answer / nagaraj u.n
2.( body or frame) earthing should be used.because in case
of 1st point is faild ,2nd point is worked .it safety for
generator & opperatore.
| Is This Answer Correct ? | 2 Yes | 7 No |
Answer / kiran patil
Only one at the star point of generator which should be
solidly grounded
