Abstract
An improved fault location method may be used to locate faults associated with one or more conductors of an electric power transmission and distribution system. The method includes the steps of detecting a fault; determining whether pre-fault data are available and, if so, using the pre-fault data to compute a load impedance and estimate the fault location using the computed load impedance; if pre-fault data are not available, determining whether pre-fault data are available in a first memory location and, if so, using the pre-fault data to compute a load impedance and estimate the fault location using the computed load impedance; and if pre-fault data are not available in the first memory location, using a pre-fault load impedance from a second memory location in estimating the fault location.
