A Comparison of Double-End Partial Discharge Localization Algorithms in Power Cables

The double-end partial discharge (PD) measurement method is the most common for measuring and localizing PD sources in power cables. sensitivity of sensor, processing speed data acquisition unit, localization algorithm are three main keys to ensuring accuracy source on A new multi-end known as segmented correlation trimmed mean (SCTM) has recently demonstrated excellent algorithm, however, only applicable methods. In this paper, mathematical equation SCTM customized match method. MATLAB simulation was conducted assess performance maximum peak detection (MPD) (SC), were compared algorithms. SC algorithms have shown that identifying bond between two cues instead signal MPD significantly increases accuracy. results show outperforms terms
