Abstract

Experimental studies are reviewed to understand the very earliest prebreakdown events in liquids. Emphasis is on cathode events that begin at lower voltages than anode events1. Other events such as anode events or those with pulsed voltages much greater than the DC or 60 Hz breakdown voltages are found in the literature as well. Photographs of stressed plane cathodes have shown events similar to those at points.2
