Therefore, it is necessary to install fault location devices on the transmission cable and distribute them on the transmission line conductors. The fault point is located and the cause of the fault is identified using the traveling wave measurement principle. The fault location device consists of a data acquisition module, a data transmission module, a power supply module and a clock module, etc. It can automatically record waveform data such as high-frequency traveling wave current and power frequency fault current on the transmission line. After the monitoring data is processed, it is sent to the data center station by wireless communication; the data center station performs data analysis, data storage, fault location, fault identification and result output, thereby realizing accurate positioning of transmission line faults and identification of fault causes;
