Abstract

Abstract: In order to explore an effective method for detecting the typical defects of metal conductive particles in GIS, using the simulation GIS to establish a set of partial discharge detection platform under AC voltage and DC voltage. Application of the ERA and the UT to carry out the measurement of partial discharge signals, then access to a large number of experimental data and maps and comparative analysis. We propose a method by analyzing for detecting the typical defects of metal conductive particles using partial discharge detection under positive DC voltage. This detection method is the most effective to the typical defects of metal conductive particles. It can discover the typical defects in time and has a little damage to the insulating properties of GIS, so that it has important application value.

Key words: partial discharge, the metal conductive particles, electrical research association, ultrasonic testing
