초록
The trend of partial discharges(PD) magnitude which occured in a artificial void at cable joint is investigated as the function of a time. The results have shown that more than 500pC could be sustained for the considerable duration so the efficiency of monitoring a PD magnitude for diagnosing cable joints is confirmed. The other defects at cable joints are now under the same test, we can get the experimental data sooner or later.
