This article presents the results of laboratory research into the influence of ageing degree of aramid-ester insulation samples on the depolarization current considering temperature effects. Also the possibilities to apply the noninvasive PDC (Polarization and Depolarization Current) diagnostic method to analyze depolarization currents of the new type of synthetic insulation.
