Protective Relay Frustrations

Solving misoperation with line parameter measurements

BY WILL KNAPEK, OMICRON USA

Between 80 to 90 percent of all power system faults involve ground. Many protective relaying schemes depend on ground distance protection to accurately sense and locate ground faults on multi-terminal sub-transmission and transmission lines. In addition to the need of dependable ground fault detection, protective relay devices must provide adequate selectivity to avoid overtripping for faults outside of its zone of protection and other...
