Detection and Localization of Neutral Wire Defect of XLPE Power Cable Based on The Time-Frequency Domain Reflectometry

시간-주파수 영역 반사파 계측법 기반 XLPE 전력 케이블의 중성선 결함 위치 측정 연구

In this paper, the diagnosis system for detecting and localizing the neutral wire defect in an energized XLPE power cable is proposed. The neutral wire defect is detectd and localized by the time-frequency domain reflectometry. To extract the reflected signal from the neutral wire defect, the adaptive RLS filtering is introduced. To verify the proposed method, the experiments for detecting and localizing neutral wire defect in active XLPE power cable is conducted.
