Abstract :
This paper presents the experimental results of partial discharge activity in paper insulation, namely pressboard and kraft paper. New paper samples of 1 mm thickness were used. The partial discharge occurrence in paper insulation under various combinations of the aging parameters such as different electrode configurations, different operating voltages, different oil temperatures, presence of water on the samples and the growth of microbiological (fungus) content on the samples was analyzed.
