Belinda Carr explains the basics of lightning protection, both internal (installation of Surge Protection Devices) and external ie. the rods installed on the building roof.
Comparing various technologies available in the USA, she emphasizes on the Prevectron advantages compared to the traditional “meshed cage” design : besides the reliability of the Early Streamer Emission air terminal, the installation of such system is also much more affordable. It requires less conductors, less fixings, less earthing pits.
