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. 410 0$aIEEE Std ;$vC62.92.4-1991. 517 $aIEEE Std C62.92.4-1991 606 $aPower transistors 615 0$aPower transistors. 676 $a621.3 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a996280458203316 996 $aIEEE guide for the application of neutral grounding in electrical utility systems$92576171 997 $aUNISA
