| Abstract: | Under the operation of high voltage power cables, the high polymer material of insulating layer will deteriorate. When the deterioration becomes serious, the insulating layer will break down and lead to accidents. The current partial discharge detection methods of power cables are analyzed such as pulse current method, UHF method, ultrasonic wave method, inductive coupled method and capacitance coupled method. |
