Abstract

L'invention concerne un système d'alimentation, destiné en particulier à des lignes téléphoniques, comprenant une charge couplée à l'alimentation en énergie par une ligne, par exemple une ligne téléphonique, la résistance de cette ligne étant importante par rapport à celle de la charge. Des dispositifs de contrôle sont placés à proximité de l'alimentation et de la charge en vue de contrôler la tension et/ou le courant dans le circuit en ligne. Un dispositif de télémesure assure la transmission de signaux de sortie depuis le dispositif de contrôle placé à proximité de la charge vers le récepteur placé à proximité de l'alimentation. Le dispositif d'alimentation est disposé de façon à recevoir des signaux provenant des deux dispositifs de contrôle et à contrôler l'énergie fournie par l'alimentation.
