Realize high-precision traveling wave fault location in distribution networks, accurate to within 100 meters

The device of this product has been successfully applied in practice, achieving a fault location of 100 meters, providing important assistance for emergency repairs in response to summer thunderstorms and strong winds
According to the traditional mode, after a 10 kV line fault occurs, it is necessary to conduct a full line or key section inspection to find the fault point, which is time-consuming and laborious. However, using this product can minimize the workload of fault inspection and significantly reduce power outage time

Product Background
In the process of ensuring and supplying electricity to the State Grid, troubleshooting and maintenance of power lines often delay the time and energy of operation and inspection personnel, making it difficult to accurately determine the location of line faults. In this case, fault indicator lights (devices) have emerged. The fault indicator light (device) can quickly and accurately display the fault location in 360 °, improve the work efficiency of operation and inspection personnel, and provide timeliness for power protection and supply
Origin (Disadvantages of the Original Method)
It is extremely detrimental to the safety of the line and equipment operation to determine the fault area by pulling the section switch and testing the power supply; The use of highly integrated distribution terminals to achieve fault identification, fault isolation, network reconstruction, reactive power/voltage control, and optimized operation of distribution networks is relatively complex and difficult to promote in some locations
Simple and efficient (currently available options)
The use of simple and low-cost fault indicator lights to quickly locate faults, or the remote transmission of fault information through fault indicator lights and communication to form an online fault monitoring system, is of great significance for fault troubleshooting
