Abstract
A system for current measurement and ground fault detection is disclosed. In embodiments, the system includes a plurality of phase current measurement coils configured to detect phase currents associated with at least one portion of a multi-phase system. The system further includes a plurality of phase current measurement circuits and a ground fault detection circuit connected to the phase current measurement coils. The phase current measurement circuits are configured to measure the phase currents detected by the phase current measurement coils, and the ground fault detection circuit is configured to measure a summation of the phase currents detected by the phase current measurement coils.
