Answer Posted / sudheer
if two alternators running parallel and both alternators
neutral grounded by one earthing strip, there is chance of
circulating current. because the unbalanced current flow
through the neutral of one alt.to second alt.by the neutral.
if both alternators earthing is separate , then no chance
of circulating current.
