절연유의 유동대전현상에 미치는 계면활성제의 영향에 관한 연구

초록

In this paper, the streaming electrification phenomena of insulating oil by metal filters and the charge elimination method were investigated. When BTA and surfactant is molten in insulating oil, BTA appear the prevention of electrification from about 5 ppm and surfactant (SP-S100, SP-S30) appear the prevention of electrification from about 20 ppm. BTA increase the conductivity of insulatinf oil but surfactant and antioxidant(DBPC) isn't affect that.
