Temperature dependence of conductive and polarization processes of PVC cable

In this paper the temperature dependence of dielectric processes is studied. For the investigation voltage response measurement was used with several discharging times that allow the investigation of various time constant polarizations. From the results of the measurement activation energies was calculated to conductivity and polarization conductivity of the insulation. The results suggest that the polarization spectrum moves towards the faster time constant polarization processes as the temperature increases.
