| Abstract: | In the light of that DC testing was not suitable for plastic insulated cables, we analyzed the ageing mechanism of different insulated cables , and put forward that plastic insulated cables were suitable for AC testing . The testing showed that adopting the 0.1Hz VLF method and using frequency-tuned resonance could find the problem of insulation quickly and accurately. Thus our experience is of very high and practical value . |
