The function of lightning and surge protection systems is to protect the devices, functional isolations and overvoltage-sensitive consumer equipment of energy distribution systems against all lightning and overvoltage damages. whole building; the outdoor lightning protection system is generally not sufficient to eliminate such malfunctions. At most of types, the defected protection device can be made operative again by changing the damaged insert; these variants are also equipped with both optical operation signal and auxiliary status contact.
