Fault location detection is critical for operating and maintaining in distribution network. The complexity of the distribution network contribute difficulty to obtain the maximum accuracy. In order to achieve the reasonable accuracy, some fault location method have been utilized. In this paper, the accuracy of fault location methods are analyzed. Two types of fault location methods, namely impedance based and linear model are discussed. The real time of the distribution network was simulated by using PSCAD software. To observe the capability of both methods, the test system was used large of non-homogeneous distribution network. Comparison results of single line to ground fault are also discussed and analyzed in this paper.
