Abstract :
In this paper, the influences of streaming electrification on creeping discharge of oil-paper insulation systems have been investigated, using an experimental model. The experimental results indicates that the initial creeping discharge voltage of an oil-paper insulation system decreases along with the increase of oil flow rate, the creeping discharge path develops towards the oil entrance, and there are polarity and position effects on creeping discharge under flowing oil conditions
