Resistance Grounding eliminates transient overvoltages and single phase Arc-Flash hazards by reducing the ground-fault current to 5 A, as well as the ability to locate the ground fault. Per IEEE Standard 141-1993, Arc-flash hazards are eliminated if the ground-fault current is reduced to 5 A or less. For systems 2.4 kV and higher, low-resistance grounding systems can be used. Properly sized resistance grounding systems solve two problems of ungrounded systems—transient overvoltages and difficulty locating ground faults.
