WebAbstract – High resistance grounding (HRG) of 480 V to 5 kV industrial power systems increases service continuity, enhances personnel safety and reduces equipment damage … WebThe grounding resistance is sized so that the magnitude of ground current during a line to ground fault would be slightly larger than the system capacitive charging current. This provides the highest value of resistance that is acceptable (hence High Resistance Ground). The grounding resistance can be smaller than this value.
