Abstract
An Electrical life is an important way to assess the insulation properties of dielectric materials. The breakdown voltage of insulating paper is an important electric feature. In this study, the electrical and physical properties of oil-impregnated insulation paper are investigated experimentally. For various periods, the breakdown voltage and time of mineral oil and vegetable oil-impregnated paper insulation were determined. The impact of insulation paper thickness on electrical and mechanical characteristics has been investigated. The results showed that as the time of immersing insulation paper in oil at room temperature increased, the breakdown voltage reduced and vice versa. As the thickness increases, breakdown voltage increases and decreases for a reduced thickness.
