Answer Posted / s.madhavan
A DG set need 4 earth stations ( pits ) Two for neutral and two for body. They should be atleast 3 mtrs apart. two neutral station s are to be connected in grid and similarly two body earth station to be connected in grid.
When two are more Dg sets are running in parallel neutral pits of only one genset ( biggest ) are used. Neutral pits of other Dg sets are disconnected. The Body earths of all Dg sets will be as it is.
