Review of Single-Phase Grounding Fault Locating in Distribution Network

Power system consists of four parts: generation, transmission, distribution and user. At present, the transmission network has been developed into multi-power ring network structure and its reliability is high. However, the distribution network adopts closed-loop structure and open-loop operation mode, so its reliability is lower. Once the distribution network fails, the power outage will occur. Nowadays, more and more attention has been paid to reliability of power supply, so it is quite necessary to research reliability of distribution network [1] .
