Operating Experience With Distance Ground Relays

DISTANCE RELAYS for protection against wire-to-wire, two wire-to-ground, and three phase faults on transmission lines have met with wide acceptance. However, the use of distance relays for protection against single wire-to-ground faults has been limited to relatively few installations. From the information available, it would seem that the Kansas Gas and Electric Company is one of the few companies using distance ground relays. The experience gained in the use of these relays over the past seven years has demonstrated their reliability and good operating performance.
