When a fault arc occurs in oil-filled electric equipment such as transformers in transmission and distribution systems, it generates a flammable gas and a dynamic pressure rise that may trigger an explosion. This paper describes a fundamental study concerning pressure rise due to an underwater arc in a closed vessel containing of air and water prior to examination of the arc phenomena in the electrical insulating oil. In this study, the pressure rises in both air and water are measured under experimental conditions of an arc current ranging from 0.5 to 6.7kA and an arc duration of 10 or 20ms. Experimental results show that the behavior of a bubble generated by the underwater arc affects the pressure rise in the air and the water as low-frequency pressure oscillation comparatively. Additionally, in water, two pressure-peaks are observed as high-frequency pulses. The first pressure peak is observed at almost the same time as the arc is ignited, while the second is produced when the bubble collapses due to vapor condensation.
