Abstract
Transmission de signaux sur des conducteurs préexistants. Un émetteur 3 applique les signaux provenant d'un appareil approprié 11, sur des conducteurs de ligne 1,2 (par exemple des conducteurs de réseau) par l'intermédiaire d'un transformateur et dans le même sens. Au récepteur 4, un transformateur similaire 6 recueille ces signaux pour les envoyer à un appareil approprié 12. Des capacités 13,14 et 15,16 découplent 1 et 2 à la terre 17. Signalisation sur des lignes de force.
