Hi guys,
I have a 370V three phase ungrounded (ABC+EGC) inverter output circuit going into a step-up transformer (delta on 370 volts side). Am I supposed to install a ground detector for this application? I guess I am not sure about the definition of ground detector, because to my knowledge, the inverter itself will always be able to detect the ground fault and trip the equipment offline for protection. Does this inverter's self protection scheme considered as a "Ground Detector" as stated in NEC?
