Abstract

The discharge processes in electro-negative gases with non-uniform field gape are composed of the formation of pulsed streamer corona, the transition of the streamers into leader step, the temporal development of the leader channel, and the stepped propagation of leader through the gap. In this paper, the first corona inception characteristics in $SF_6$ gas and $SF_{6}-N_{2}$ mixtures, related to the propagation of loader and the space charge effect, were experimentally investigated with positive and negative transient impulse voltages.
