Abstract

L'invention porte sur un système pour surveiller une puissance qui possède un dispositif de surveillance de transformateur de distribution polyphasé (PDTM) unifié qui s'interface avec au moins trois conducteurs électriques connectés électriquement à un transformateur. De plus, le dispositif PDTM mesure un courant et une tension de chacun des trois conducteurs électriques. En outre, le système possède une logique qui calcule des valeurs indicatives d'une puissance correspondant au transformateur sur la base des courants et des tensions mesurés et émet des données indicatives des valeurs calculées.
