The aim of the RodCheck system is to give visual information on the intensity of the lightning current caught by the OPR even from a long distance. Lightning rod is a security device that permits to limit risk and therefore contributes to the safety of the people. It is important to figure out directly its degree of aging, which is linked to the lightning strike current to which it has been subjected.
On many sites lightning rods are usually equipped with counters that detect the flow of current without necessarily giving information about its intensity.
The RodCheck system has been developed so as to solve this specific security issue and it provides an estimate of the intensity of the lightning strike at first glance. This visual indicator is made of a UV resistant EPDM shell, mounted directly on the OPR external spark gap.
