System and method for intelligently searching and analyzing grounding fault of distribution network line

The invention discloses a system and method for intelligently searching and analyzing a grounding fault of a distribution network line. The system comprises a hand-held terminal, a control center and a monitoring management cloud platform which are connected in sequence, and the control center is connected with the terminal. The method comprises the following steps of: S1, connecting the handheld terminal with a grounding line; S2, judging a fault direction through a current test module; S3, judging a specific fault result through a fault judgment module; S4, making the handheld terminal display and store a fault result and upload the fault result to the control center; and S5, making the control center gather power grid circuit faults for analysis and optimization and upload the power grid circuit faults to the monitoring management cloud platform. According to the technical schemes, intelligent judgment of a fault direction is achieved through optimization of the handheld terminal of the distribution networ
