The device is charged via the lower electrodes using the ambient electrical field (several thousand volts/metre when storms are approaching).
This means the prevectron 3® is a fully autonomous system requiring no external power supply.
Whilst dynamically assessing the development of the surrounding electrical field, the prevectron 3® detects the appearance of downward leaders. This innovative and patented optimax® system is then activated to neutralize the space charges, which naturally occur around the lightning conductor.
The controlled ionization process and the new optimax® technology guarantee the triggering of an upward leader ahead of any other protruding point within the area to be protected.
The prevectron 3® is the preferential point of impact for the lightning discharge and provides the structure with maximum protection.
