Abstract

Partial discharge(PD) detection is an important means to monitor and diagnose the insulation condition of electrical equipment. Detecting the partial discharge condition of the equipment and finding and dealing with the insulation defects in time can effectively avoid the occurrence of insulation faults[1]. In this paper, a GIS partial discharge location and monitoring system based on loop signal loop is designed. By studying the principle of loop time difference location and signal processing algorithm of UHF signal, a GIS Partial Discharge Monitoring System Based on UHF method is developed to realize on-line monitoring and location of partial discharge[2]. The later test shows that the monitoring system has strong stability, high sensitivity and accurate positioning, which can meet the requirements of on-line monitoring and positioning of partial discharge in GIS.
