Abstract

Pre-breakdown voltage is a phenomenon of dielectric breakdown affecting insulation’s performance. The faster pre-breakdown voltage of insulation, the more significant its dielectric degradation. In this paper, pre-breakdown voltage in oil insulation was investigated by using DC high voltage in laboratory scale. Under testing, the streamer development was recorded by using a high-resolution camera. The measured current was synchronized with an image that was picked up during the oil insulation testing. By this experiment, the characteristics of the current in phenomenon pre-breakdown voltage at oil insulation was studied. The results showed that the measured current of pre-breakdown phenomenon in oil insulation under 28 kV to 30 kV excitation voltage is in a range 100 mA - 150 mA.
