Partial discharge (PD) measurement and pattern recognition for insulation defect is an effective tool for condition assessment. The patterns obtained by PD detection system contain characteristic features of the insulation defect. This paper presents a PD experiment of semi-conductor layer tip defect in the joint, and applies a new feature method based on 2-D wavelet decomposition and pattern edge...
The extraction of partial discharge (PD) signals from excessively noisy environment is crucial to on-line PD measurement. Recent research shows that the wavelet transform (WT) has achieved good effect in noise rejection in PD on-line detection. This paper presents some vital issues of WT implementation in extracting PD signals, including optimal mother wavelet selection, decomposition level selection,...
The suppression of noise is crucial prior to any partial discharge (PD) data analysis in on-line PD measurement. Recent research shows that the Wavelet transform (WT) has achieved good effect in noise rejection in on-line PD detection. This paper presents the vital issues of WT implementation in PD signals extraction, including optimal mother wavelet selection, decomposition level selection, threshold...
