Title:
ARRESTOR DEVICE
Document Type and Number:
Japanese Patent JPS5951500
Kind Code:
A
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.
