Abstract
To overcome the high cost, low spatial resolution of the electrical discharge localization systems for the Gas Insulated Line (GIL), a non-intrusive distributed optical fiber sensing system based on Distributed Acoustic Sensing (DAS) is proposed. Firstly, the principle of the proposed discharge localization system is introduced. Then, efficiency of the proposed sensing system was demonstrated based on pencil-lead break experiments. Furthermore, the localization results of the experiments using the GIS spacer flashover discharge indicate that the system meets the requirement of GIL discharge localization.
