Description

technical field [0001] The invention relates to detection equipment in the electric power industry, in particular to a detection device for concealed conduction between a power transmission tower and a ground network. Background technique [0002] The ground resistance test of the transmission tower is a routine test in the power industry. The ground resistance value of the transmission tower plays an extremely important role in reducing the lightning trip rate of the line. The periodic ground resistance measurement of the tower before and during use is very important. critical and important. According to the relevant electric power regulations, the connection between the grounding down conductor and the iron tower should be in good contact, and it should be easy to disconnect and measure the grounding resistance. However, in the actual test work, it was found that there is a hidden conduction between the ground network of some transmission towers and the iron tower, that i...
