How to calulate the NGR resistance ?
Answer / raghavendran
NGr can be calculated by dividing the system voltage by the
allowable let through current from the resister to earrth.
say the system voltage is 600 volts and the allowable let
through current is 25A then the NGR value could be 600/25 =
24ohms.
