| Abstract: | A 110kV substation cable terminations insulation breakdown occurred so after it been putted into operation.By the accident,The author analysis and comparise several commonly used methods of detection cable.The author think the GIS high voltage cable terminations should been an on-line partial discharge detect soon after it put into operation,if the conditions to carry out testing on a regular basis,it will better to ensure the safe operation of high voltage cable. |
