Research on Partial Discharge Detection Based on Spectrum Analysis in the Complicated and Strong Electromagnetic Environment of Substation

Partial discharge(PD) detection is an effective method for evaluating the insulation state of power equipment. If partial discharge is not detected in time, it will cause insulation damage of power equipment, which will affect the safe and stable operation of the power system. With the development of modern society and science and technology, the application of Internet of Things technology in electric power operation is more and more extensive, and the electromagnetic environment of electric power operation site has become more complicated. Therefore, it is necessary to study the partial discharge detection technology of power equipment based on spectrum analysis in the complicated and strong electromagnetic environment of substation.
