Prevectron 2 Millenium series
The PREVECTRON®2 is operating in three stages:
The ionization device is charged via the lower electrodes using the ambient electrical field (several million volts/meter when storms are prevalent). This means the PREVECTRON®2 is a fully autonomous system requiring no external power supply.
The ionization phenomenon is controlled by a device which detects the appearance of a downward leader: the local electrical field increases rapidly when a discharge is imminent.The PREVECTRON®2 detects changes within the field, making it the first E.S.E. air terminal to react at the precise moment the downward leader develops from the cloud to the ground.
Early triggering of the upward leader using a system of spark ionization between the upper electrodes and the central tip. The PREVECTRON®2s ability to trigger an upward leader ahead of any other protruding point within the protected area ensures it will be the preferential point of impact for the lightning discharge.
