Surge arresters - Metal-oxide surge arresters with external series gap (EGLA) for overhead transmission and distribution lines of a.c. systems above 1 kV Ingestion-build-53008 b) a description of theWhat is BS EN IEC 60099 8 Externally gapped line arresters (EGLA) about? BS EN IEC 60099 8 is the eighth part of the IEC 60099 multi series that discusses surge arresters. BS EN IEC 60099 8 covers metal oxide surge arresters with external series gap (externally gapped line arresters (EGLA)) that are applied on overhead transmission and distribution lines, only to protect insulator assemblies from lightning caused flashovers. BS EN IEC 60099 8 defines
