Abstract

The paper presents the results of DC conductivity dependence of a transformer oil impregnated pressboard, with moisture content of 2.9% by weight, measured for temperature from 20 °C to 80 °C and a field strength from 10 kV/m to 1000 kV/m. It was found that the non-linear phenomena, which presence cannot be explained by the theory of ion conduction of oil-paper insulation, is intensifying with increase of the electric field strength.
