Utilizing Fault Resistance to Test Distance Relays

Taking power grid protection to an all-new level

BY JASON BUNEO & RENE AGUILAR, Megger

The testing of distance relays has evolved from testing simple electromechanical relays to the newest modern microprossesor relays. Most modern relays employ advanced algorithms that not only compare the direction of voltages and currents in the system but also rather look at other system components. For example, many modern relays utilize various methods in order to determine the direction of...
