Online Monitoring of Transmission Line
In recent years, with the rapid development of the power grid, more and more cables are used in urban power grids. With the growing size of cable lines, a serious problem is increasingly exposed-cable line faults. The problems of fire prevention, gas prevention, explosion prevention, waterproofing and theft prevention of cable tunnels are becoming more and more important. In order to meet the "five preventions" requirements of cable tunnels, the operating environment of the cables must be monitored, and problems should be discovered and handled in time to avoid major problems.
