Abstract

This paper presents the effect of moisture and dust on streaming electrification in transformer oil, in order to investigate the electrification tendency of oil adding moisture an dust. Authors designed series electrification device to analyse streaming electrification phenomena easily. Experimental results show that the streaming current is linearly increased with oil velocity and it has a peak value at about a 50 [%]. Adding of moisture and dust in oil decreased charging level and it was dominant in case of moisture.
