要約(英語): When a fault arc occurs in oil-filled electric equipment, it generates a flammable gas and a dynamic pressure rise. In this study, the pressure rises due to the arc are measured in a closed vessel containing air and oil for different arc depths. The pressure rises in air and oil with different depth are measured under experimental conditions involving an arc current 6.6kA, an arc duration of 100 milliseconds. Experimental results show that the frequency of pressure fluctuation varies with the depth of the arc. Our approximate calculation of the pressure fluctuation with consideration of the oil flux is consistent with the experimental results.
