N2 - Cross-linked polyethylene (XLPE) insulation cable is the main type of cable in use now. Its main insulation is aging with the increasing of service years. Two methods are used to diagnose the condition of the cable insulation-polarization/depolarization current (PDC) and frequency domain spectroscopy (FDS). The PDC is a time domain method, while the FDS is frequency domain. In this paper, we put forward a method to get the dissipation factor curve of FDS under low frequency by carrying out the PDC experiment. This method is based on three R-C series branches extended Debye model. In this model each branch stands for a type of polarization process. Firstly, The measurement of cable samples aged for different days is carried out to get the PDC and dissipation factor curves. Then, the PDC curves are fitted with a third-order exponential decay function, and the parameters of the extended Debye model are calculated. Comparing the calculated dissipation factor curves with the measured, we find that they agree very well with each other under low frequency range. By this way, we can reduce the measuring time.
