Abstract

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.
