摘　　要：应用二进小波变换对动力电缆进行故障检测,经EMPT仿真数据的分析,证明该方法有很高的精确度。With the automatization of the mine improved, the techniques of power cable fault detection is being developed, and many detection methods and instruments come out. The causes and quality of the fault production, off-line monitoring methods and their comparison and analysis are outlined in this paper, especially the detection methods based on the wavelet transformin this paper. Results of analysis through EMTP prove this method has high precision.
