Abstract

The general features of electrical breakdown between two electrodes in a liquid have been known for decades. When breakdown occurs, a flash of light is emitted, an acoustic signal is emitted, the potential difference between the electrodes decreases rapidly, and the current flowing between the electrodes increases rapidly. The continuing development of light sources, high-speed cameras, and high-speed electronic measuring ’ systems have made it possible to study the breakdown process in increasing detail. This lecture summarizes some of the results obtained using these various measurement techniques to investigate electrical breakdown in liquids under pulsed voltage.
