Abstract

This paper presents experience with field PD testing on solid dielectric switch. Testing was performed within project of improvement of condition assessment on MV solid dielectric switchgear equipment in the field. Method of testing was developed by few of authors of the paper. Field PD testing is very demanding in environment with high background noise, disturbances and cross talk between phases. The challenge is to find the feasible solution for type of sensors and their coupling with a test object. Other challenge was to find adequate software for analysis and diagnostics. Measuring system with synchronous 3 channel PD data acquisition was used. Advanced noise and PD separation techniques: 3 phase amplitude relation diagram (3PARD) and synchronous multi-frequency measurements (3FREQ) were used for reliable analysis and diagnostics.​​​​
