Anotation

IEC 60076-2:2011 applies to liquid-immersed transformers, identifies power transformers according to their cooling methods, defines temperature rise limits and gives the methods for temperature rise tests. This new edition includes the following significant technical changes with respect to the previous edition: - the winding hot-spot temperature rise limit was introduced among the prescriptions; - the procedures for the temperature rise test were improved in relation to the new thermal requirements; - five informative annexes were added in order to facilitate the implementation of this standard. La CEI 60076-2:2011 sapplique aux transformateurs immerges dans un liquide, identifie les transformateurs de puissance selon leurs methodes de refroidissement, definit les limites dechauffement et presente les methodes dessais dechauffement. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - les modalites de realisation des essais dechauffement ont ete ameliorees de facon a tenir compte des nouvelles exigences de performances thermiques; - cinq nouvelles annexes informatives ont ete introduites pour faciliter lapplication de cette norme.
