This paper proposes a fault location method based on sinusoidal steady state analysis which can locate the single phase-to-ground short-circuit fault with single-ended measurement in an overhead three-phase electric power distribution lines. By measuring and calculating certain fundamental parameters of the system as well as the voltages and currents at the sending-end, which contain corresponding fault information, the location and resistance of fault candidates can be determined by solving nonlinear distributed-parameter equations. Physical model experiments show that this method performs well.
