The substation grounding grid condition detection system injects variable-frequency excitation current into the grounding grid through surface grounding down conductors. It measures the induced surface magnetic flux density and coordinates, employs differential algorithm-based detection to generate topological diagrams, conducts corrosion analysis and defect localization for horizontal grounding grids, providing basis and decision-making support for on-site excavation.
