This paper proposes a system-level overall solution that includes three levels of substation, distribution line and distribution automation master station. Through the transformation of power distribution and power distribution, the substation small current grounding line selection device, arc suppression coil automatic control equipment, power distribution terminal, and distribution automation main station are integrated. With a variety of comprehensive criteria as the core of technology, the operational effects of information interoperability, resource sharing, functional readiness, and unified monitoring are achieved. It can provide the production management department with the closed-loop processing method of “fault identification-isolation processing-data management-analysis promotion”. At the same time, different solutions can be configured for different site requirements, which can meet the needs of different regions and different site conditions, and effectively improve the site. Applicability solves the problem of single-phase grounding identification of cable lines.
