Annotation of standard text IEC/TS 62332-2-ed.1.0 :
IEC TS 62332-2:2014 is applicable to EIS containing solid and liquid components where the thermal stress is the dominant ageing factor, without restriction to voltage class. This part specifies a sealed tube test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS). One aspect of this procedure is to also provide a method to assign thermal classifications to materials used in EIS where solid and liquid components are both used. This procedure describes a comparative ageing method whereby a reference system composed of kraft paper and mineral oil is compared to a candidate system of any combination of solid and insulating liquid. The test procedures in this part are specifically applicable to liquid immersed transformer insulation systems. L'IEC TS 62332-2:2014 est applicable aux SIE contenant des composants solides et liquides, ou la contrainte thermique est le facteur de vieillissement predominant, sans restriction de la classe de tension. La presente partie indique une procedure d'essai a tube scelle pour l'evaluation et la qualification thermiques des systemes d'isolation electrique (SIE). Un aspect de cette procedure est egalement de fournir une methode d'attribution de classifications thermiques aux materiaux utilises dans les SIE qui utilisent tant des composants solides que des composants liquides. Cette procedure decrit une methode de vieillissement comparative ou un systeme de reference compose de papier kraft et d'huile minerale est compare a un systeme candidat de toute combinaison de composant solide et de liquide isolant. Les procedures d'essai decrites dans la presente partie s'appliquent specifiquement aux systemes d'isolation a transformateurs de puissance immerges dans un liquide.
