Abstract

The present invention relates to a system (10) for performing a partial discharge test of a factory joint (1) joining a first high voltage cable section (2) and a second high voltage cable section (4). The system (10) comprises a first insulation system (40) for electrically insulating a joint side part (2SJ) of the first semiconductive sheath (2S) from a remaining part (2SR) of the first semiconductive sheath (2S) and a second insulation system (50) for electrically insulating a joint side part (4SJ) of the second semiconductive sheath (4S) from a remaining part (4SR) of the second semiconductive sheath (4S). The remaining part (2SR) of the first semiconductive sheath (2S), the remaining part (4SR) of the second semiconductive sheath (4S) and the first conductor (2C) and/or the second conductor (4C) of the respective cable sections are grounded. A high voltage transformer (20) is supplying a test voltage to the semiconducting sheath (1S) of the factory joint (1S) during a test period. A partial discharge sensing system (30) for sensing partial discharges in the factory joint (1) during the test period.
