With the increase of the coverage area of the domestic distribution network, the probability of failure of the distribution network system is also greatly increased. In this paper, a grounding fault line selection system is designed for the small current grounding system of the distribution network. Firstly, taking the fault recorder as the data source, a single-phase grounding fault line selection system is built to monitor the single-phase grounding fault of the small current grounding system in the distribution network of each substation and select the fault line accurately and quickly. Finally, a 380 V physical simulation platform is built to simulate the fault line selection test. Taking Changchun area as an example, a single-phase ground fault occurs in the 66 kV system of Jingyang substation. Through the analysis of the system, the feasibility and accuracy of the line selection system are verified
