The aim of a lightning rod is to attract bolts of lightning from ionized air and conduct them to earth in order to prevent causing harm to people or constructions. The first lightning rod was called Franklin as a tribute to Benjamin Franklin, its inventor. Its structure is formed by a metallic shaft and a collector.
PSR Pararrayos is a Spanish leader company engaged in the manufacture, sale, installation and revision of these conductors and protection systems against lightning. PSR models generate electric fields outwards which act as collector, increasing the protecting area against lightning. This equipment works autonomously, once the grounding of the lightning rod is suitable, it should be unified with the perimeter network (if any), to provide equipotential of the entire network with grounding. One bolt of lightning may generate 1GW of instant power.
