CENELEC
CLC/TC 81X Lightning protection
European Norm
91.120.40 Lightning protection
This European Standard specifies the requirements and tests for isolating spark gaps (ISG) for lightning protection systems. ISG's can be used to indirectly bond a lightning protection system to other nearby metalwork where a direct bond is not permissible for functional reasons. Typical applications include the connection to - earth termination systems of power installations, - earth termination systems of telecommunication systems, - rail earth electrode of AC and DC railways, - measuring earth electrodes for laboratories, - installations with cathodic protection and stray current systems, - service entry masts for low- voltage overhead cables, - bypassing insulated flanges and insulated couplings of pipelines.
