Abstract
A lightning protection system having a sensor for detecting a polarity of atmospheric charges, a direct current power supply, a controller interactively connected to the power supply and to the sensor so as to select a polarity of the direct current in relation to polarity of atmospheric charges, a first lead connected to one location on the structure, and a second lead connected to another location on the structure such that direct current passes from the first lead to the second lead. The controller selects a polarity of the direct current that is opposite to the polarity of the atmospheric charges sensed by the sensor.
