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 is the 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 ;C62.92.4-2014.C62.92.4-2014 - IEEE Guide for the Application of Neutral Grounding in Electrical Utility Systems--Part IVIEEE Std C62.92.4-2014 (Revision of IEEE Std C62.92.4-1991) - Redline: IEEE Guide for the Application of Neutral Grounding in Electrical Utility Systems--Part IV: Distribution - RedlineIEEE Guide for the Application of Neutral Grounding in Electrical Utility Systems--Part IVIEEE Std C62.92.4-2014 Electric power supply, Constant-currentElectric power supply, Constant-current.621.3NjHacINjHaclDOCUMENT9910135337303321IEEE guide for the application of neutral grounding in electrical utility systems2576171UNINA
