Abstract

In industry, there have been several documented failures on the lower (oil side) region of high voltage power transformer bushings. In these cases, the failure mode was considered to be due to localised discharges, as a result of
accumulated surface contaminants. Given failure is often catastrophic, it is therefore difficult to establish the exact point of failure. In this paper, a numerical model that simulates the electric field and equipotential distributions for an oil
impregnated paper bushing with contaminants on the lower porcelain surface is presented.
