Abstract. A method is proposed for investigation of dielectrics by carrying out Selective Polarization-Depolarization cycles (PD cycles) of different constant temperatures. The new thermograms are similar to the thermally stimulated discharge current (TSDC) thermograms, and allow one to determine all basic parameters of the dielectric under investigation. General expressions for the new thermograms are derived. They show that the new method, compared with the TSDC method, has some important advantages.
