What is the advantage of Neutral graunding transformer
insted of Neutral graunding Resistance in generating
station explain briefly.
Answer Posted / devang machchhar
with the same value of resistance, NGT shows more
resistnace in ground circuit and limit the current for
instantanious high fualts at the first 3 power cycles,
providing safety to the generator or transformer.
