Abstract (en)

[origin: WO8403594A1] A lightning protector for overhead electric lines comprises at least one of the following elements: a spark-arrester (111, 112), a ground lead and a device for the connection of electric cables. Measures for reducing the impedance of the elements forming the circuit for the discharge to the ground of the shock wave due to atmospheric charges are proposed.
