Title (EN) METHOD FOR PREDICTING THE PROBABILITY OF ABNORMALITY OCCURRENCE IN OIL-FILLED ELECTRICAL APPARATUS
(FR) PROCÉDÉ DE PRÉDICTION DE LA PROBABILITÉ D'UNE OCCURRENCE D'ANOMALIE DANS UN APPAREIL ÉLECTRIQUE REMPLI D'HUILE
(JA) 油入電気機器における異常発生の可能性を予測する方法
Abstract:
(EN) A method for predicting the probability of abnormality occurrence in an oil-filled electrical apparatus, which comprises subjecting a sample of insulating oil withdrawn from a transformer in operation to compositional analysis, calculating the estimated concentration of dibenzyl disulfide in the insulating oil in its virgin state from the result of the analysis, and predicting the probability of abnormality occurrence in the oil-filled electrical apparatus on the basis of the level of the estimated concentration.
(FR) L'invention porte sur un procédé de prédiction de la probabilité d'une occurrence d'anomalie dans un appareil électrique rempli d'huile, qui comprend le fait de soumettre un échantillon d'huile isolante prélevé d'un transformateur en fonctionnement à une analyse compositionnelle, calculer la concentration estimée de disulfure de dibenzyle (DBDS) dans l'huile isolante dans son état vierge à partir du résultat de l'analyse, et prédire la probabilité d'occurrence d'anomalie dans l'appareil électrique rempli d'huile sur la base du niveau de la concentration estimée.
(JA)  本発明は、油入電気機器における異常発生の可能性を予測する方法であって、稼動中の変圧器から採取した絶縁油の成分分析から、該絶縁油中の未使用時におけるジベンジルジスルフィド濃度の推測値を算出し、この推測値の高低から油入電気機器における異常発生の可能性を予測する予測方法である。
