K-fault diagnosis method for analog circuits is introduced to line fault location in a distribution network for the first time. The line fault location based on K-fault 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 a fault detection criterion including the voltage response.
