Lightning conductor with piezoelectric device for initiating the corona effect

摘要

The present invention relates to a lightning conductor with a piezoelectric device for initiating the corona effect. It comprises a metal rod terminated by a tip and connected to the ground by an electric conductor. In the vicinity of the tip are provided one or more electrodes, which are electrically connected to one or more piezoelectric crystals, on which a means exerts a mechanical pressure. This makes it possible to raise the electrodes to an adequate potential for producing charged particles in the vicinity of the tip.
