Problems solved by technology
[0002] Due to the single and inefficient inspection methods of overhead wires in the past (mainly visually following the wires or observing through telescopes, and in a few cases by helicopter inspections), UAV inspection wires have the advantages of safety, stability, flexibility, and low cost. The use of UAVs for inspection of overhead lines has become a research hotspot in our country due to the advantages of low cost and low personnel injury. And the radiated electromagnetic field generated by the discharge phenomenon may affect the safe operation of drones composed of electronic circuits, etc.
