Development of external diagnosis for terminal in XLPE cables
2009 Transmission & Distribution Conference & Exposition: Asia and Pacific, 2009 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
