Abstract

Prebreakdown phenomena in dielectric liquids which have various molecular structure are observed in detail for point-to-plane electrode configuration under an impulse voltage condition. Experiments are carried out by using a high-speed schlieren photography and a current measurement system by LED simultaneously. As a result, the influence of a molecular structure on the streamer propagation and the polarity effect of streamer discharge is discussed.
