Abstract
This paper presents results on the effect of enforced co-field oil flow velocity and of temperature on the breakdown voltage of transformer oil using point-to-plane electrodes. Tests were carried out on degassed oil and oxygen-saturated oil for negative and positive point polarities over the temperature range 20°C - 85°C and flow velocities from 0.0 to 170 cm/s and for two gap lengths: 400 μm and 1 mm.
