Abstract :
Industry has become aware of the problem of severe generator damage due to stator ground faults. It has been suggested that, to prevent this damage, the practices employed for neutral grounding should be changed. This paper provides an analytical perspective on this problem and suggests that the real issue is the manner in which the neutral of the generator itself is grounded
