Abstract :
In this paper, we have calculated the TSC curve and the discharge current due to two interfacial polarizations in order to interpret experimental results on EPR quantitatively. The simulation results showed that the interfacial polarization due to a small portion of filler, with a long relaxation time, presents a peak around 30°C, and the discharge current at room temperature is caused by this polarization. On the other hand, we have affirmed that the polarization caused by the remaining large portion of filler, which has a short relaxation time, presents a small TSC peak at a lower temperature. The discharge current due to this polarization appears in the short time region compared with the measurement time of the discharge current. The simulations are compatible with experimental results
