Abstract An electrically conductive device (6) is positioned in the vicinity of a lightning rod point (1, 2), where it is electrically isolated from the lightning rod (1) and the ground conductor (3). This device (6) comprises a first component (7) extending radially from the lightning rod (1) and having terminal spikes (8, 9, 10) for facilitating the adjustment of said component to the potential of the surrounding atmosphere. The device (6) also comprises a second component (11) terminated by an electrode (12), which is positioned at a sufficiently short distance from the lightning rod (1) and in such a manner that a discharge takes place between the electrode (12) and the lightning rod (1) as a result of the voltage developing across the gap between said conductive device (6) and the lightning rod (1). The advantage of the system is that the efficiency of the lightning protector is greatly improved by comparison with lightning protectors provided with a radio-active source, while operating without such a source.
A lightning protector assembly, characterized in that it comprises at least one electrically conductive device (6) positioned in the vicinity of a lightning rod point (1, 2) and electrically isolated from both this point (1, 2) and a conductor (3) connecting the lightning rod point to the ground, said device (6) comprising a first component (7) terminated by at least one spike (8, 9, 10) for facilitating the adjustment of the device (6) to the electric potential of the atmosphere, and a second component (11) extending as an electrode (12) positioned at a sufficiently short distance from the lightning rod point (1), so that, at least in the event of stormy weather, an electric discharge takes place between the electrode (12) and the lightning rod point (1) as a result of the voltage developed across the gap between said conductive device (6) and the lightning rod point (1), such a discharge being sufficient by itself to improve the efficiency of the lightning protector.
