Initiation of Leader in Long Air Gaps at Quasi-Steady Corona near Stressed Electrode
Non-stationary streamer-free corona at slow (for seconds or dozens of seconds) voltage change is theoretically studied and numerically simulated. The obtained results are used to investigate the effect of injected space charge on initiation and development of a leader in long air gaps. The focus is on the initiation of upward lightning from a stationary grounded object in a thundercloud electric field. The main results are also applicable to leader process in long laboratory air gaps at constant voltage.
