Abstract

L'invention concerne un transformateur de distribution qui stocke des informations d'état, un dispositif d'affichage et un procédé de commande du transformateur de distribution. Le transformateur de distribution selon l'invention comporte une mémoire externe pour stocker des informations concernant des périodes et des moments afin de détecter un état du transformateur, un bloc de détection d'état pour détecter un état interne du transformateur, et un module de commande qui stocke, dans la mémoire, des informations d'état de transformateur envoyées par le bloc de détection d'état, lorsque la période et le moment stockés dans la mémoire arrivent. L'invention stocke, dans une mémoire, des conditions globales du transformateur, à savoir la charge, le courant, la température, l'indice d'acidité de l'huile isolante, à la période et au moment voulus par l'utilisateur, et ces informations enregistrées peuvent être utilisées ultérieurement en tant qu'état historique dans le cas d'une défaillance de transformateur ou le cas échéant. Ainsi, une défaillance de transformateur peut être évitée à l'avance, et lorsqu'une défaillance se produit, on peut éviter une seconde défaillance en vérifiant l'état du transformateur à un emplacement problématique correspondant.
