Abstract—Analog circuit fault diagnosis method is introduced to line fault location in a distribution network. The line fault location based on analog circuit diagnosis theory can be performed by fault line sector identification and distance estimation followed. This paper deals mainly with fault line sector identification. A new technique depending on obtaining measurable nodes voltage response corresponding to a particular current excitation at the header terminal of distribution lines is proposed. Line fault sector is determined by the proposed fault detection criterion.
Index Terms—Fault diagnosis, fault line sector identification, analog circuit, distribution network.
