Abstract: An Artificial Neural Network based fault location algorithm for distribution feeders is presented in this paper. The principle of the algorithm is quite simple and it only uses a phasor ofvoltage and current measured at the substation, but it can estimate the location of the fault with very good resolution. The first phase of voltage and current will be calculated and then according to the type of fault, the trained ANN estimates the fault location. According to the different types of faults, 3 differentANN's will be used for fault location estimation. The simulations were done in an IEEE 34 feeder test system and the results show that ANNs can estimate fault location with a good resolution for a wide range of fault resistance.
