Abstract
A lightning protection method and device with compound actively generated plasma and passively produced plasma provide lightning protection without the need for grounding of the protected object. The device has lightning rods with a plasma piping inside. The high density plasma generated by an active plasma generator is blown through the piping, spread out at the tips of the rods and compounded with the plasma passively produced by the corona discharge on the tips under the action of lightning cloud electric field. The compound plasma dissipates the electric charges, on the tips of the rods, inducted by the lightning cloud electric field, and neutralizes the electric charges of the lightning, preventing a thunderstruck to a protected object related to the rods.
