ABSTRACT:
A lightning protection device for reducing exposure of an object to be protected from conventional and upward lightning strikes. The device includes a support structure adapted to be grounded and space charge producing conductors wound around the support structure and forming coils for producing space charge of opposite polarity to a cloud charge, in a proximity of the object to be protected. The space charge induces a charge on the object to be protected of an opposite polarity to a charge induced on the object to be protected by the cloud charge and inhibits a formation of streamers from the object to be protected. Each space charge producing conductor has a diameter not exceeding 0.1 mm for reducing a corona inception voltage of the support structure upon which each space charge producing conductor is wound, in both dry and wet conditions.
