Anotation

IEC 63012:2019 defines requirements for the characterization of unused modified esters or blends of unused esters used as insulating liquids for electrotechnical applications. It does not cover liquids that contain any proportion of used liquids. The liquids covered by this document are intended mainly for transformer applications. Unused modified/synthetized esters are derived from a natural or synthetic base, or are blends of both. This document covers a variety of ester liquids not covered by other standards specific to natural esters (IEC 62770) or synthetic esters (IEC 61099). As it addresses various categories of liquids, this document also covers a wide range of values for certain performance characteristics. An important property is viscosity, which can affect the design and cooling performance of electrical equipment. A categorization is defined based on the kinematic viscosity of the different liquids. The category of low viscosity ester liquids is established. LIEC 63012:2019 definit les exigences relatives a la caracterisation des esters neufs modifies ou des melanges desters neufs, utilises comme isolants liquides pour des applications electrotechniques. Il ne couvre pas les liquides contenant une proportion quelconque de liquides usages. Les liquides couverts par le present document sont principalement destines aux applications dans des transformateurs. Les esters neufs synthetiques/modifies sont derives dune base naturelle ou synthetique, ou sont des melanges des deux. Le present document couvre une variete de liquides a base desters non couverts par dautres normes specifiques aux esters naturels (IEC 62770) ou aux esters synthetiques (IEC 61099). Traitant dune grande variete de liquides, le present document couvre egalement une large plage de valeurs pour certaines caracteristiques de performance. La viscosite est une propriete importante qui peut influencer la conception et les performances de refroidissement du materiel electrique. Une classification est definie sur la base de la viscosite cinematique des differents liquides. La categorie des liquides a base desters a faible viscosite est donc etablie.
