Fault diagnosis method for substation grounding network

In this paper, a fault diagnosis method of grounding network is studied, which includes: collecting magnetic field data of multiple conductors of grounding network according to the excitation current and acquisition parameters in the grounding network; Each magnetic field data is identified for the grounding grid conductor; The collected magnetic field data is processed; Send the processed magnetic field data to the substation server through wireless communication; Substation server according to the grounding network conductor identification, confirm the processing of the grounding network first conductor magnetic field data is less than the first preset threshold, diagnose the grounding network first conductor fault. This application has accurate fault location, high detection efficiency, and can realize online real-time detection.
