Charging current
(OP)
Hi,
I`m looking for guidelines on how to measure the capacitive charging current on a 400 V 3500 kVA system.The intention is to limit the ground fault current close to the capacitive charging current.
Thanks.

Ground-Fault Detection, Charging Current, and Neutral-Grounding Resistor Selection
Typically, charging current will be 0.5 A per 1000 kVA on low-voltage systems, and 1.0 A per 1000 kVA on medium-voltage systems. Consequently, 5-A, 15-A, and 25-A grounding resistors are common.
