Abstract

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 restrain noise interfering and pick up PD signal key eigenvalue effectively. The technique for on-line detection of partial discharge in XLPE power cable have been improved in this paper
