ISGs can be used to indirectly bo
34、nd 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; auxiliary earth electrod
35、es of voltage-operated, earth fault circuit breakers; 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 insula
36、ted couplings of pipelines. This standard does not cover applications where follow currents occur. NOTE Lightning protection system components (LPSC) can also be suitable for use in hazardous conditions such as fire and explosive atmosphere. Due regard will be taken of the extra requirements necessa
37、ry for the components to be installed in such conditions. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
