Description
technical field [0001] The invention belongs to the field of monitoring and management of power systems, in particular to a lightning discharge induction monitoring device for power transmission and distribution lines. Background technique [0002] At present, most of the transmission lines and power distribution rural grid lines in our country are laid out in the suburbs and mountainous areas with few people and inconvenient transportation. Especially in mountainous areas, the micro-meteorological environment is complex, and it is very difficult to find faults. In the analysis of the cause of overvoltage, more than 10% of the overvoltage is caused by external lightning flashover, and the main reason is induced overvoltage, and a small amount is direct lightning flashover. However, since the lines are mostly laid out in mountainous areas and suburbs, it is difficult to accurately monitor the area where the lines are located by ordinary weather forecasts and weather informat...
