Analysis of anti-interference technology in on-line monitoring of partial discharge of electrical equipment

In the insulation materials of power equipment, there are often impurities or foreign substances, which makes the field strength distribution in the insulation materials of electrical equipment have a large difference. If the field somewhere in the insulation material is stronger than the breakdown field strength, partial discharge of the insulation material will occur, and further lead to a decrease in the performance of the insulation material. To this end, it is necessary to monitor the partial discharge of power equipment insulation materials online in real time, so as to grasp the performance of insulation materials in real time. Among them, anti-interference technology is one of the key technologies in the on-line monitoring of partial discharge of electrical equipment, which is analyzed in detail in this paper, which has certain value for improving the technical level of on-line monitoring of partial discharge of electrical equipment.
