Anotation

IEC 63585:2026 This document gives guidelines to the transformer operator in evaluating dissolved gas analysis (DGA) data obtained from natural ester according to IEC 62770 and synthetic ester according to IEC 61099 in liquid filled transformers and similar equipment. This document includes the following: - gas generation in a natural and synthetic ester-filled transformer; - DGA interpretation methods; - gas concentration guide values valid for the use of DGA interpretation tools; - nterpretation of the dissolved gas analysis results; - recommended actions based on the interpretation of dissolved gas analysis results; - examples of faulty equipment. IEC 63585:2026 Le present document fournit des lignes directrices a loperateur de transformateur pour evaluer les donnees danalyse des gaz dissous (AGD) obtenues a partir de transformateurs remplis de liquides a base dester naturel selon lIEC 62770 et dester synthetique selon lIEC 61099 et de materiels analogues. Le present document comprend les elements suivants: - production de gaz dans un transformateur rempli desters naturels ou synthetiques; - valeurs indicatives de concentration de gaz valables pour lutilisation doutils dinterpretation de lAGD; - methodes pour l’interpretation des resultats des gaz dissous; - actions recommandees en fonction de linterpretation des resultats de lanalyse des gaz dissous; - exemples de materiels defectueux.
