초록
In a large power transformer, an insulating oil is forced to circulate for cooling the heat generated by the losses within the windings and core. When oil flows and rubs against various materials, including insulating paper and steel, electrostatic charges are separated at the interface of the oil and the solid material. This paper considers the polarity and the streaming electrification of the various materials which are used in transformer. As a result of this study, it is confirmed that the leakage current on the solid material, such as paper, is charged negative. On the other hand, the solid material, such as steel, is positively charged.
