Risk assessment according to lightning protection standards, both for ESE air terminals (NF-C 17102; UNE 21186/1M) and for Franklin rods and meshed conductors (IEC-EN 62305), requires a detailed knowledge of the structure to be protected. Therefore, the work of and expert is recommended.
The new European Normative EN 50550, regulating the protection against transient and power frequency overvoltages, has recently been published. The mentioned standard defines as power frequency overvoltages (POP) those whose duration is relatively long (several cycles) and may cause damages to the installation and to the electrical equipment.
The standard establishes quality, safety and electromagnetic compatibility requirements for power frequency overvoltage protectors.
Aplicaciones Tecnológicas lightning air terminals and other devices for lightning protection cover eight buildings of the airport.
