Original Abstract

This paper reports on an investigation into the application of denoising techniques to improve the arrival time detection of UHF partial discharge (PD) signals, with the aim of refining the spatial localization of PD in power transformers, gas insulated switchgear, and other systems where partial discharges can occur. Noise reduction methods can be applied to signals from various measurement systems including UHF methods or acoustic emission detection. Most existing measurement systems do not normally apply any sophisticated signal processing to suppress noise in the spatial localization of discharges. This can potentially cause inaccuracies in the location of insulation defects position and may inadvertently misdirect modification or repairs of equipment, maintenance inspection of exposed parts or subsequent servicing operation.
