Annotation of standard text IEC/TR 62874-ed.1.0 :

IEC TR 62874:2015 is a Technical Report which provides guidance for the estimation of consumed thermal life of transformers cellulosic insulators, through the analysis of some compound dissolved in the insulating mineral oil. A comparison between analytical results of 2-furfural (2-FAL) and carbon oxides and their correspondent typical values estimated for different families of equipment gives information on the estimated thermal degradation of papers. LIEC TR 62874:2015, qui est un rapport technique, est destine a estimer la vie thermique consommee de lisolation cellulosique dun transformateur, grace a lanalyse de certains composes dissous dans lhuile minerale isolante. Une comparaison entre les resultats danalyse de 2-furfural (2-FAL) et d oxyde de carbone et de leurs valeurs types correspondantes estimees pour differentes familles dequipement donne des informations sur la degradation thermique estimee des papiers.
