Description

technical field [0001] The invention relates to a monitoring system, in particular to an on-line monitoring system for the insulation of high-voltage electrical equipment. Background technique [0002] The capacity of my country's power grid continues to increase, and the voltage level has also increased significantly, which puts forward higher requirements for the safe operation of the power grid. Insulation defects can cause insulation accidents that affect the safe operation of equipment and power grids. Therefore, the insulation monitoring of old equipment is particularly important. However, in the actual insulation monitoring process, it is often encountered that due to the defects of the insulation monitoring system, the leakage cannot be detected at the first time, or a small amount of leakage cannot be detected, resulting in insulation accidents that affect the safe operation of equipment and power grids. It is an urgent problem to design a high-sensitivity and high...
