SIEMENS NON-GAPPED LINE ARRESTERS (NGLA) – LINE SURGE ARRESTERS WITHOUT SPARK GAP

Non-gapped line surge arresters (NGLA) offer a high degree of mounting flexibility and operational reliability. Depending on the tower design and the arrangement of insulators and lines, these arresters can either be installed directly on the insulators or on the tower.

Thanks to their high energy absorption capacity, non-gapped line arresters offer a very high level of protection against overvoltages caused by lightning and network-generated switching impulse current overvoltages.

To galvanically isolate the line surge arrester from the line voltage in the unlikely event of a fault or thermal overload, a disconnector is installed in series. It automatically and immediately disconnects the line surge arrester from the line voltage. This allows the affected overhead line to continue to be used until replacement can be scheduled.
In addition to the line surge arresters, the new ACM advanced monitoring system can be installed to provide arrester condition monitoring. This system monitors wirelessly and provides detailed information about leakage currents and converted energy.
