Last week I had a chance of quick reviewing some references about spark formation. Those included some investigation about how it is affected by: - AC application (different freq., DC component, rise time, etc.) - successive pulses - electrode shape In a nutshell, all of the above factors influenced the breakdown threshold so much (e.g. 50%) that you really couldn't state a kV amount simply according to the curvature of the electrodes. That's why I'm asking, where this 26kV/cm is from?
