Lightning strikes is one of nature’s most destructive element, a single lightning bolt can carry up to 1 billion volts of energy and can reach temperatures of 28,000ºC.
Lightning Protection Systems are designed to give this energy a safe and low impedance path to earth. There are three parts to a structural Lightning Protection System:
- Air Termination Network
- Down conductors
- Earth Termination Network
All Lightning Protection Systems must be inspected and tested on a regular basis by competent personnel using calibrated test equipment.
Woodward Group recommends testing lightning protection systems every eleven months. The significance of such a program is that over a twelve-year period, the protection system would have been tested under all seasonal conditions. The variations in seasonal conditions can significantly affect the performance of your lightning protection system in resistance and other characteristics.
We conduct all inspections and tests in accordance with the standards laid out in BS EN 62305.
