Surge arresters - Metal-oxide surge arresters with external series gap (EGLA) for overhead transmission and distribution lines of a.c. systems above 1 kV1 Scope This part of IEC 60099 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. This document defines surge arresters to protect the insulator assembly from lightning caused over voltages only. Therefore, and since metal oxide resistors are not permanently

all the requirements under PD CEN/TR 17223 apply to the organizations’ activities and the applicable regulatory requirements need to be applied
