Development of a Fault Locator for Applying Overhead HVDC Line using FMCW Radar Technology

Abstract

This paper presents the fault location system for pulse radar method using FMCW radar technology at overhead HVDC line. This system operates that triggered off a line protection system (automatic mode) and/or user's control (manual mode), hence we can not only comprehend the fault location but also exploit the health check of transmission line. This proposed method is tested via experiments at the EPDC's Hokkaido-Honshu HDVC link and the CRIEPI Akagi testing center's 22kV distribution line. The applied test results corroborate the practical performance of fault occurrence at ground fault situation and break line situation.
