A quantitative correlation between streamer velocities and impulse breakdown voltages has been established for point-plane geometries. We have extended these studies to less divergent fields (rod-plane) where we have identified two regions for impuls

The recent activity in the area of prebreakdown streamer development has produced a considerable quantity of data characterizing the phenomena. It is not the aim of this paper to review in detail this work, much of which has been discussed in two rec

In this paper we present a comprehensive account of our results on streamer propagation in dielectric fluids in point‐plane geometries. Propagation velocities for both positive and negative streamers have been determined as a function of the follow

Measurements of streamer velocities in a highly refined mineral oil are reported for negative and positive polarities using a point-to-plane geometry. The effects of several additives are investigated. The results indicate that whereas the negative s

The electrical breakdown of liquid dielectrics is a complicated process and there is no single theory that explains all the experimental results. Specific experimental conditions will be the determining factor as to which of the several mechanisms wi
