Abstract
A new fault location algorithm is presented which uses voltage and current values measured from single terminal of faulted transmission line. The distributed model of transmission line is applied and the effect of capacitance on it is precisely considered, its precision is hence greatly enhanced. The method has been simulated by EMTP and proved very accurate.
