The relay calculates the distance to fault with fault resistance compensation. For the
fault location feature, a fault is defined as an event that has caused a current level
greater than the pickup threshold of an overcurrent protection feature programmed
to "Trip" or "Trip & AR" (760 only), which has remained for sufficient time to cause
the relay to produce a Trip command. After this has happened, the apparent
distance to the fault is calculated in a background mode, maintaining all other
features in operation. The distance calculation is based on the assumptions that:
