[0002] The lightning protection and electrical testing grounding ring is a device specially used to prevent overhead insulated wires from being broken by lightning and to test and ground them during maintenance and construction. It has two main functions. First, the grounding wire can be hung on the lightning protection and electrical testing grounding ring as an electrical testing device to help workers determine whether the line is energized and ensure the safety of maintenance operations. Second, the freewheeling power frequency arc is moved to the electrical testing grounding ring to burn, thereby protecting the insulated wire from damage and improving the lightning resistance of the line.

[0003] At present, the installation of lightning protection and electrical detection grounding rings usually involves high-altitude live operations, which carries high risks. Whether using an insulated boom truck or relying on manual pole climbing, there are technical and safety challenges.
