| Abstract: | An experimental system of electrical treeing in XLPE cable insulation at high temperature was designed.The electrical tree growth and partial discharge characteristics at different temperature in high voltage XLPE cable insulation were studied under 13 kV power frequency voltages.The results indicate that the effect of temperature on the tree growth is dominant.The whole system can be used to the real-time observation of electrical tree growth and continuous partial discharge measurement at high temperature... |
