To verify the reliability of 110 kV XLPE cable joints a long term prequalification test was carried out at IPH. 12 joints of various manufacturers were integrated in a circular 110 kV XLPE cable test loop. The short distances between the joints required selective PD measurement and localisation location to measure PD from each joint separately. Therefore directional coupler sensors (DCS) were integrated at each joint to provide a sensitive and unequivocal PD measurement and localisation
