Abstract
The aim of this work is the investigation of layered dielectrics under DC voltage stress. For this purpose, two layered test samples were made, which contain one layer without fillers and the other made of the same silicone, mixed with a specific amount of graphite additive. Thus, the two layers have different electrical conductivities, which are also dependent on the temperature and the electric field. The change in the electrical conductivity with the DC field is investigated by measuring the polarization and depolarization currents (PDC) at different field strengths on prepared samples. The electrical conductivity can be calculated from the stationary value of the polarization current, the applied DC voltage and the geometry of the sample. In addition, each measurement series is repeated at different temperatures, so that the effect of temperature on the insulating material can also be investigated. For these tests it has been ensured that, after the addition, a homogeneous distribution of the graphite in the material prevails. Another difficulty is the production of flawless and bubble-free samples, which is why the test material is subjected to several degassing and vibration processes.
