Abstract

Une méthode de surveillance d’un transformateur (10) comprend un changeur de prises (16), des renseignements extraits comprenant une amplitude de courant de circulation et/ou un temps de courant de circulation (tC) couvrant au moins une partie de l’opération du changeur de prises représentée par au moins une forme d'onde de différence de courant et/ou un temps de courant de transition (tR) couvrant au moins une partie de l’opération du changeur de prises représentée par au moins une forme d'onde de perte de puissance.
