EN 60099-8:2011

Surge arresters - Part 8: Metal-oxide surge arresters with external series gap (EGLA) for overhead transmission and distribution lines of a.c. systems above 1 kV

IEC 60099-8:2011 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 standard defines surge arresters to protect the insulator assembly from lightning-caused overvoltages only. Designs with the EGLA's external series gap installed in parallel to an insulator are not covered by this standard.

Überspannungsableiter – Teil 8: Metalloxid-Überspannungsableiter mit externer Serienfunkenstrecke (EGLA) für Übertragungs- und Verteilungsleitungen von Wechselstromsystemen über 1 kV

Parafoudres - Partie 8: Parafoudres à oxyde métallique avec éclateur extérieur en série (EGLA) pour lignes aériennes de transmission et de distribution de réseaux à courant alternatif de plus de 1 kV

La CEI 60099-8:2011 concerne les parafoudres à oxyde métallique, de ligne avec éclateur extérieur en série (EGLA) utilisés sur les lignes aériennes de transmission et de distribution, uniquement pour protéger les ensembles isolateurs contre les contournements provoqués par la foudre. Cette norme définit des parafoudres destinés à protéger l'ensemble isolateur uniquement contre les surtensions provoquées par la foudre. Les conceptions avec des EGLA à éclateur extérieur en série montés en parallèle sur un isolateur ne sont pas couvertes par la présente norme.

Prenapetostni odvodniki - 8. del: Kovinsko-oksidni prenapetostni odvodniki z zunanjim zaporedno vezanim iskriščem (EGLA) za nadzemne prenosne in razdelilne vode v izmeničnih sistemih nad 1 kV (IEC 60099-8:2011)

Ta del IEC 60099 zajema kovinsko-oksidne prenapetostne odvodnike z zunanjim zaporedno vezanim iskriščem (EGLA), ki se uporabljajo na nadzemnih prenosnih in razdelilnih vodih samo za zaščito izolacijskih sklopov pred prebojnim vžigom zaradi delovanja strele.
Ta standard določa prenapetostne odvodnike, ki ščitijo izolacijski sklop samo pred prenapetostjo, ki jo povzroča delovanje strele. Iz tega razloga in ker kovinsko-oksidni upori niso trajno povezani z vodom, ta standard ne obravnava naslednjih postavk:
• prebojne napetosti pri preklopnem impulzu;
• preostale napetosti pri strmem tokovnem impulzu in preklopnem tokovnem impulzu;
• toplotne stabilnosti;
• odpornosti proti dolgotrajnemu tokovnemu impulzu;
• električne napetosti v odvisnosti od časa trajanja prenapetostnega odvodnika;
• preskusa prekinjal;
• vpliva električne napetosti na delovanje pri staranju.
Glede na poseben koncept zasnove in posebno uporabo na nadzemnih prenosnih in razdelilnih vodih so vpeljane nekatere edinstvene zahteve in preskusi, kot so preskus preverjanja za koordinacijo med odpornostjo izolatorjev in zaščitno ravnjo EGLA, prekinjevalni preskus sledilnega toka, preskusi z mehansko obremenitvijo itd.
Ta standard ne zajema zasnov z zunanjim zaporedno vezanim iskriščem EGLA, nameščenim vzporedno z izolatorjem.
