2.7 Grounding
Proper power system grounding is very essential for personnel safety, equipment protection, and power continuity to electrical loads. Special attention should be given to grounding location and means for minimizing circulating ground currents, as well as ground-fault sensing. Electrical power systems require two types of grounding, namely, system grounding and equipment grounding; each has its own functions [55]. The IEEE Green Book, IEEE Recommended Practice for Grounding of Industrial and Commercial Power Systems, ANSI/IEEE C114.1, Std.142, is the authoritative reference on grounding techniques [56].
