Abstract :
To develop diagnostic method for terminals in aged XLPE cable lines, an external diagnosis of deterioration signals relating to partial discharge generated in the aged terminal has been investigated. The authors focused on acetylene as the particular gas produced by discharge from the results on partial discharge experiment using sheet specimens with a void. It was indicated from the results that gas analysis, aimed at detection of acetylene in the air in the metal casing of the terminal, had possibility to the applied to the external diagnosis. As result, based on the results of the correlation study between gas analysis results and dismantlement investigation of aged CV cable line terminals, it was determined that it is possible to use acetylene analysis as a deterioration diagnosis method for aged terminals.
