Description

Technical Field

[0001] The utility model relates to the technical field of grounding equipment, in particular to a grounding rod data acquisition circuit. Background Art

[0002] During power system maintenance and construction, grounding wires play a vital role as technical equipment protecting maintenance personnel, electrical equipment, and grid operation safety. However, in practice, the usage status and connection location of grounding wires cannot be effectively monitored online in real time. Maintenance personnel can only obtain information about grounding wire usage through on-site inspections and shift handovers. Temporarily attached grounding wires are easily forgotten during emergency power restoration or expansion of operations, leading to power outages caused by forgetting to remove a short-circuiting grounding wire and allowing power to be restored with the switch still on. This poses a significant safety hazard to grid maintenance, operation, and construction personnel.
