Accelerated Thermal Aging of the Liquid Dielectrics

The essence of this paper is to investigate and compare current characteristics of thermally degraded liquid dielectric using impedance spectroscopy. The theoretical part explains electrophysical phenomena in dielectrics and characterization of the method of impedance spectroscopy in the frequency and time domain. The practical part takes into account the experiment, which is focused on the used sample of liquid dielectric, description of the measuring workplace and analysis of experimental results in the frequency and time domain.
