Problems solved by technology

[0002] At present, in the power supply system, leakage faults often occur, and agricultural power personnel need to eliminate the faults in time; after the on-site personnel arrive at the scene, they first need to judge the type of fault, and then quickly eliminate the fault according to the corresponding fault type; however, due to the complexity of the power supply line In addition, many agricultural power personnel are often not exposed to a large number of on-site faults, so it takes a lot of time to detect and analyze the fault types, which reduces the efficiency of emergency repairs
