电缆护层缺陷的测寻

DETECTION OF DEFECT OF CABLE SHEATH

通过对高压电缆非金属外护层缺陷产生的原因和类别、电缆护层缺陷的分类、电缆护层缺陷的测寻分析比较 ,着重介绍了高压电桥法、直流电压比法 (电阻比 )

Based on the analysis and comparison of reasons of causing defect of outer sheath and defect types the HV bridge method, DC bridge method and the problem which should be pay attention is introduced.
