ISGs can be used to indirectly bon

Typical applications include the connection to: earth termination systems of power installations; earth termination systems of telecommunication systems; auxiliary earth electrode
42、s 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 insulat
43、ed 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 necessar
