If two generator running parallel, at that condition both ngr
Taken in line or taken any one ngr, but why any one or both
Ngr in line?
Ngr is use for which purpose?
Answer Posted / harkamal singh
NGR Neutral ground resistance
Ngr panel is use allow to minimum range of unbalance current of Electrical alternators and add extra resistance in series of neutral link.
