Annotation of standard text IEC 62770-ed.2.0 :
IEC 62770:2024 describes specifications and test methods for unused natural esters in transformers and similar liquid-immersed electrical equipment in which a liquid is required as an insulating and heat transfer medium. The exposure of natural ester to air leads to deterioration of the insulating liquid. Use of natural esters is therefore restricted to sealed units, or with the conservator tank protected from the contact with atmosphere by a membrane or other suitable system. IEC 62770:2024 decrit les specifications et methodes dessai applicables aux esters naturels neufs dans les transformateurs et materiels electriques immerges dans du liquide analogues qui necessitent un liquide en tant que milieu isolant et caloporteur. Lexposition de lester naturel a lair entraine une deterioration du liquide isolant. Lutilisation des esters naturels est donc limitee a des unites scellees, ou avec le conservateur protege du contact atmospherique par une membrane ou tout autre systeme approprie.
