Research of Partial Discharge Monitoring for Switchgear Cabinet Based on LSSVM

By Han Shai Gen, Guan Shi Lei, Wu Yan, Bo Zhi Xin, Ding Yan and Chen Li An

Abstract

Now, there are many influencing factors of partial discharge(PD) for switchgear cabinet, but very few methods used for switchgear cabinet monitoring. In this paper, Partial discharge of switchgear cabinet is identified based on Least Square SVM (LSSVM) used for comprehensive evaluation of switchgear cabinet. Partial discharge ultrasonic signal of time and frequency domain are gave to get two stable characteristic bands in MATLAB tool. It provides a theoretical basis for partial discharge monitoring to ensure proper and efficient operation of the switchgear cabinet
