The earthing system plays a vital role in a co-ordinated lightning and surge protection system. It is responsible for safely dissipating the lightning currents to the ground but just as importantly, it plays a fundamental role in the efficient operation of surge protection devices.
Lightning protection earthing systems use a wide range of materials, in numerous configurations, to achieve a maximum resistance level of 10 ohms or less, as recommended by BS 7430 “Earthing”.
