Insulation failure of XLPE cable system, particularly in joints and terminations, mostly attributes to local defects resulted from inadequate manufacturing or poor installation workmanship. Since it is well-acknowledged that partial discharge (PD) has a relationship with the discharge source (fault or defect), PD detection and pattern recognition have been widely accepted as a means to provide information...
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...

Based on variety of fractal dimension scale and principle of self-similarity, this paper presents a new digital analysis system for partial discharge (PD) signal detecting, recognizing and processing. Application of fractal character calculating, detecting PD pulse signal of XLPE power cable approach very high frequency (VHF) using high-frequency and wide-band electromagnetism coupling is able to...
