Locating motor ground faults with intelligent motor control on high-resistance grounded (HRG) systems

Application engineer Yzhi Alexander demonstrates the pulse detection feature in Eaton's Power Xpert C445 intelligent motor management relay. Within a high resistance grounding (HRG) system, the Power Xpert C445 can monitor and detect ground faults.
