应用高频脉冲电流法进行局部放电测试

确定了电缆终端B相内部存在局部放电。最后通过对电缆终端进行解体发现其内部严重受潮

进一步验证了高频脉冲电流法在XLPE电缆终端带电测试的有效性及仿真判据的实用性。

Abstract

The detection principle of the high frequency pulse current method is introduced

and EMTP/ATP is employed for modeling and simulation to obtain the criterion of partial discharge in cable terminal according to the simulation results. Considering the anomalies in infrared temperature measurement of a 110 kV XLPE cable terminal

the high frequency pulse current method is adopted to detect the partial discharge to determine that the partial discharge occurs in cable terminal B phase. Disassembly inspection reveals heavy moisture in the cable terminal

verifying the validity of the high frequency pulse current method and the practicability of the simulation criterion for live detection of XLPE cable terminal.
