The Antiimpatto® protection system enters the electromagnetic field that precedes the formation of the lightning leader, acting as a passive reflector with a very rounded directivity function. The radio-frequency energy invested in the antenna is therefore partly consumed and partly reflected.
The Antiimpatto® system does not centralize the lines of force of the electrostatic field, and is comparable to a multidirectional and multi-range antenna for radio frequency modulations. The energy reflected by the lightning rod exerts a dispersive action influencing both the mechanisms of separation and accumulation of charges, and the formation of partial microdischarges. The lightning leader, hindered in its genesis, has difficulty in producing itself and the charge has an spatial and temporal evolution devoid of the last macroscopic phase.
The Antiimpatto® system also eliminates the effects of interference and electromagnetic induction, the primary cause of damage to electrical and electronic systems and normally generated in traditional prevention systems, from the passage of lightning from the receptors (lightning rod or Faraday cage) to the earthing network (grounding).
Ingelva defends every property from the action of lightning with its design and the most appropriate sizing of the Antiimpatto® system, guaranteeing its effectiveness for 10 years with insurance cover from Allianz of €1.5 million.
