Abstract: Disclosed are a device and method for detecting defects of a high-voltage cable cross-bonded grounding system. The method selects a protective grounding box of a cross-bonded grounding system, respectively connects a signal excitation coupler to A-phase, B-phase and C-phase coaxial cables of the protective grounding box, selects a stable signal with a frequency different from a power frequency or a field interference frequency, and tests effective current values and phases responded by the A-phase, B-phase and C-phase coaxial cables when the stable signal with the frequency F1 is injected into the A-phase, B-phase and C-phase coaxial cables of the protective grounding box; and obtains resistances and inductances of branch circuits of the cable cross-bonded grounding system by calculation according to measurement data, and determines if the cable cross-bonded grounding system has a connection defect.
