Description

[0002] With the continuous advancement of the power system, the requirements for the safety and stability of the power system are becoming higher and higher. The laying range of the distribution network is getting larger and larger. In addition to underground cables, overhead cables are also included. Overhead lines can avoid occupying ground space and reduce human damage. However, since overhead lines are located in the air, they are difficult to detect and troubleshoot. With the continuous increase in the failure rate in recent years, the larger the laying range of the overhead network, the more difficult it is to find the fault point. Once a fault occurs, it takes a lot of time to explore and inspect.
