Paper Abstract

In this work, we investigate streamer discharge characteristics including phase graph of discharge, hysteretic effect of pattern evolution, dimension variation of filaments, breakdown moment of discharge etc. with a specially designed discharge setup which has two transparent liquid electrodes and a corresponding photoelectric detection system. The detection system is composed of lens, apertures, photomultiplier, digital camera, spectrograph, high-voltage probe, and oscilloscope. It is found that diameter of filaments decrease as applied voltage is increased when patterns are in the regime of spots patterns. However, diameter of filaments increases when patterns undergo a transition to a different type. It is found that compares with applied voltage, patterns evolution exists a hysteretic effect. In addition, experiment results indicate that patterns structure has closely relationship to temporal correlation of discharge.
