Abstract

In this paper, the streaming electrification characteristics of insulating oil were examined when the oil is contacted with solid materials in a circulating system. The streaming current($I_s$) increases with increasing oil velocity and temperature, and electrification properties depend on species of metal materials. $I_s$ in the gauze-contained electrification apparatus increases with increasing oil temperature below the temperature of 43[>$^{\circ}C$], but decreases above 43[>$^{\circ}C$]. On the other hand, $I_s$ is positive electrificated for the pipe of Fe, Cu, while it is negative electrificated for Sus. When insulating oil flows through a car fuel filter, $I_s$ increases linearly with increasing oil temperature.
