抄録

It has been reported in polymer insulation that the ac loss current in phase to applied voltage is distorted with developing of water trees. We have also obtained the distorted ac loss current from the water treed polyethylene sheets. In order to analyze this distorted ac loss current, we have discussed with the modified Maxwell-Wagner two layer model, in which the capacitance C₁ for the non-degraded region is connected in series to the parallel combination of the capacitance C₂ and the non-linear conductance G₂ for the water treed region. This model takes account of a non-linear dependence of conduction current through G₂ on voltage across the capacitance C₂. By numerically solving a non-linear differential equation for the electric charge on the capacitance C₂, the ac loss current was calculated. The observed wave forms were compared with the calculated ones by changing parameters of non-linear conduction.
