Annotation of standard text IEC 60099-9-ed.1.0 :
IEC 60099-9:2014 applies to non-linear metal-oxide resistor type surge arresters without spark gaps designed to limit overvoltages in HVDC converter stations of two terminal, multiterminal and back-to-back type up to and including an operating voltage of 1 100 kV. The standard applies in general to porcelain-housed and polymer-housed type arresters but also to gas-insulated metal enclosed arresters (GIS-arresters) solely used as d.c. bus and d.c. line/cable arresters. Arresters for voltage source converters are not covered. Arresters applied on the a.c. systems at the converter station and subjected to power-frequency voltage of 50 or 60 Hz principally without harmonics are tested as per IEC 60099-4. The arresters on a.c.-filters are tested according to this standard. Keywords: testing of gapless metal-oxide surge arrestors for HVDC converter stations LIEC 60099-9:2014 sapplique aux parafoudres a resistance variable a oxyde metallique sans eclateur concus pour limiter les surtensions dans les postes de conversion CCHT de types bi poles, multi poles et dos a dos, jusqua et y compris une tension de regime de 1 100 kV. La norme sapplique generalement aux parafoudres a enveloppe en porcelaine et a enveloppe synthetique, mais egalement aux parafoudres sous enveloppe metallique a isolation gazeuse (parafoudres blindes ou parafoudres GIS) utilises seulement comme parafoudres de bus c.c. et comme parafoudres de cable/ligne c.c. Les parafoudres pour convertisseurs de source de tension ne sont pas couverts. Les parafoudres appliques sur les reseaux a courant alternatif au poste de conversion et soumis a une tension a frequence industrielle de 50 Hz ou 60 Hz principalement sans harmonique sont soumis a essai selon lIEC 60099-4. Les parafoudres sur les filtres c.a. sont soumis a essai selon la presente norme. Mots cles: essais des parafoudres sans eclateur a oxyde metallique dans les postes de conversion CCHT
