Abstract

L'invention concerne un dispositif de transmission de puissance apte à transmettre de la puissance électrique fournie par une source de puissance électrique à au moins un dispositif récepteur connecté audit dispositif de transmission par l'intermédiaire d'un réseau de communication, via au moins un câble de transmission de données comportant au moins une paire de conducteurs, un courant électrique étant transporté sur au moins une paire de conducteurs. Le dispositif de transmission de puissance selon l'invention comporte, pour chaque dispositif récepteur connecté, un dispositif de protection (150) apte à réaliser une disjonction pour protéger la source de puissance électrique en cas de dysfonctionnement électrique du dispositif récepteur ainsi qu'un équilibrage de courant électrique transporté sur la au moins une paire de conducteurs, ledit dispositif de protection (150) comportant au moins un composant commun (100, 102) contribuant à la fois à la réalisation de ladite disjonction et dudit équilibrage.
