Abstract

Lightning conductor with a piezoelectric device for starting the corona effect. A lightning conductor pole rests on a support fixed by means of a ball. Under the action of the wind, the pole moves out of the vertical position until a shoulder abuts against a flange of the support. With the wind continuing to act on the pole, the latter exerts a considerable force on the support and the reaction force or torque is transmitted to the piezoelectric device by means of the ball.
