Title (EN) METHOD OF ESTIMATING LIFE OF INSULATION FOR ELECTRIC DEVICE USING RESIN INSULATOR
(FR) PROCEDE D"ESTIMATION DE LA DUREE D"ISOLATION D"UN DISPOSITIF ELECTRIQUE UTILISANT UN ISOLATEUR EN RESINE
Abstract: front page image
(EN)A resin piece for a monitor built in an electric device, or a resin piece forming a part of an insulating composition of the electric device, is removed after the lapse of a suitable operating time. The ratio of the number of hydrogen atoms to that of carbon atoms or of the number of oxygen atoms to that of carbon atoms is measured to estimate the life of the insulation for the electric device.
(FR)Une piece de resine pour un moniteur incorpore dans un dispositif electrique, ou une piece de resine faisant partie d"une composition d"isolation d"un dispositif electrique est enlevee apres un temps de fonctionnement approprie. Le rapport entre le nombre d"atomes d"hydrogene et celui d"atomes de carbone ou entre le nombre d"atomes d"oxygene et celui d"atomes de carbone est mesure pour estimer la duree d"isolation du dispositif electrique.
