Classes of distribution systems grounding are defined. Basic considerations in distribution system grounding--concerning economics, control of temporary overvoltages, control of ground-fault currents, and ground relaying--are addressed. Also considered are use of grounding transformers, grounding of high-voltage neutral of wye/delta distribution transformers, and interconnection of primary and secondary neutrals of distribution transformers.IEEE Std ;C62.92.4-1991.IEEE Std C62.92.4-1991Power transistorsPower transistors.621.3NjHacINjHaclDOCUMENT996280458203316IEEE guide for the application of neutral grounding in electrical utility systems2576171UNISA
