Abstract
An equipment for a preventive lightning protection of at least partly neutralizing the electric potentials of the atmosphere's charges. This is accomplished through the application of a high-potential d.c. voltage to a vertical structural post carrying on its top a member adapted to radiate an electric field of a magnitude, polarity and duration adjusted by a control unit in response to the condition of the atmospheric charge as sensed and relayed to the control unit by a sensor.
