Distributed fault diagnostic devices for transmission lines

As of 2022, this device has been applied to more than 70,000 lines in more than 9,000 circuits, with a monitoring length of over 800,000 kilometers, and have diagnosed more than 7,000 tripping faults. It has been applied in "extra-ultra-high voltage" lines, "Tibet-China connection" lines, "three major DC" lines, intelligent lines, "three-span" lines, and has provided key data support for the analysis of tripping of long-distance UHV transmission lines for multiple times. The economic and social benefits are outstanding.

 Hazard monitoring and early warning devices for transmission line

This device has been applied to power grids in more than 20 provinces and cities, including Jiangsu, Zhejiang, Chongqing, Shandong, Inner Mongolia, Guangdong, and Hainan, with a total of over 500 power lines connected to the grid. It has successfully warned and diagnosed dozens of hidden dangers in power lines.

 High voltage cable fault diagnostic devices

This device has been installed on nearly a thousand power lines in the fields of State Grid, Southern Power Grid, rail transit, and wind and solar new energy, with over 2000 sets of monitoring terminals (including the 500kV cable of the Shanghai World Expo Tunnel). It has successfully diagnosed cable line faults more than a hundred times and has been widely recognized by users.

 Distribution line fault diagnosis device
