DC Field Effect on Streaming Electrification in Insulating Oil

절연유의 유동대전특성에 미치는 직류전계의 영향에 관한 연구

In this paper, the result of experimental investigation into the streaming electrification phenomena of insulating oil under an external dc field effect is described. Energization by positive dc voltage enhanced the streaming electrification. but when the applied voltage was negative, the polarity of streaming current was field strength dependent.
