Abstract : It is shown experimentally how the velocity of the moving electrode effects on the flashover voltages between the stationary plane electrode and the moving electrode. In case of stationary electrode system, the space charges produced from the tip of the electrode distribute to relax the strength of the electric field at its point, and prevent the flashover. While the electrode set in motion, it is difficult to suppress the development of the corona or streamer and it becomes easy to lead to flashover, because the tip of the electrode moves always prior to the existing region of space charges. This explains why the lightning is triggered easily by a moving aircraft or a launching rocket carrying a wire connected to the ground. (Author)
