The Prevectron's lower electrodes collect energy from a naturally occurring ambient electrical field that increases as much as ten thousand volts per meter as a storm approaches. |
 |
The collected electrical energy is stored in capacitors inside the Prevectron. Prior to a lightning strike the atmospheric electrical field increases rapidly, activating a patented triggering device. |
 |
The trigger releases the stored energy through the upper electrodes at the tip of the air terminal and initiates an upward leader at the optimum moment. |
 |
The Prevectron's upward leader connects with the downward leader and the resultant lightning strike is directed safely to ground through the central rod. |
