Research on Failure Detection Method of High Voltage Cable Terminals

  The failure rate of XLPE cable terminations is much higher than that of the cable body.In order to solve the operational failure problem of the high voltage cable terminals,the conjunction of ultrasonic method and pulse current method are tested on the polyethylene material and the cable terminal in the lab.When the voltage of 6kV is applied on the cable,the partial discharge will occur at the cable terminal.The amplitude of the voltage detected by the pulse current method is about 20mV and the result detected by ultrasonic method is about 80mV.The test data show that the comprehensive application of the ultrasonic and pulse current method can improve the measuring accuracy of the partial discharge results.It can suppress interference effectively and achieve an accurate diagnosis of the partial discharge sources.
