The present invention relates to practical plasma. Because in the plasma lightning arrester of the prior art, the intensity of the balancing charge is usually insufficient and disappear quickly, there is no sufficient time and intensity to balance out the induced charge on the surface of object to be protected, therefore the plasma lightning arrester of the prior art can not prevent the object from lightning strike effectively. The present invention appends a RC charging-discharging circuit on the passage way of balancing charge in series, so that the passing period of balancing charge is extended, and the lightning strike can be prevented effectively. The charge amplifier is arranged to intensify the balancing charge and enhance the protecting ability against lightning strike.
