The TIDA-00442 TI design provides a reference solution for detecting ground faults in inverter based drives. Inverter current is measured on both dc-positive and dc-negative buses using shunt ...

For modern distribution protection, Negative Phase Sequence (NPS) Protection is often relegated in favor of common elements such as Overcurrent (OC) or Earth Fault (EF), but NPS is an incredibly ...

Medium-voltage motors are critical to a facility’s power system. Not only are they expensive, but their failure can have crippling, long-lasting impacts on a plant’s operation. As such, properly ...

The odyssey for ground-fault protection (GFP) of marine equipment began with the addition of Sec. 555.3 in the 2011 NEC. This section called for “ground-fault protection” on the main overcurrent ...

NOJA Power highlights how modern Automatic Circuit Reclosers such as its OSM single triple ACR can assist utilities in protection schemes for isolated or high-impedance networks to minimize disruption ...

Created to protect personnel from electric shock, GFCI-type operations now help protect equipment as well. • Ground-fault sensing now protects equipment as well as personnel. • The magnitude of ...
