Abstract:
1. A lightning protection system for a metallic structure comprising: a first sensor means for detecting a polarity of atmospheric charges; a direct current power supply; a controller means connected to said power supply and to said sensor means, said controller means for selecting a polarity of said direct current power supply in relation to polarity of atmospheric charges as sensed by said sensor means; a first lead means extending from said controller means for passing the selected polarity of the direct current power supply to a first location on the structure; and a second lead means extending from said controller means for connecting to a second location on the structure such that the direct current of selected polarity passes from said first lead means to said second lead means, a second sensor means for sensing an intensity of the atmospheric charges, said controlling means for adjusting an amperage of said direct current power supply in relation to the intensity of said atmospheric charges.
