This paper describes the comparison between the simulated results of thermal gradient using COMSOL and actual observed results of thermal gradient in modified thin film pulsed electroacoustic system, together with the effect of thermal gradient on space charge at room temperature and 50 °C. The results show the presence of thermal gradient facilitates the charge injection and electric field distortion, resulting in accelerated aging of insulation under HVDC.
