White Paper:
Neutral Grounding Resistor Monitoring

Resistance grounding prevents many of the problems that are associated with ungrounded and solidly grounded electrical distribution and utilization systems. Resistance grounding can limit point-of-fault damages, eliminate transient overvoltages, reduce arc-flash hazards, limit voltage exposure to personnel, and provide adequate tripping levels for selective current-based ground-fault detection and coordination.
