Title (EN) COUPLING COMMUNICATIONS SIGNALS TO UNDERGROUND POWER LINES
(FR) COUPLAGE DE SIGNAUX DE COMMUNICATION A DES LIGNES D'ALIMENTATION SOUTERRAINES
Abstract:
(EN) In one embodiment, a system for coupling communications signals to an underground medium- voltage power line includes a medium- voltage power line, a ground conductor, one or more ferrites, and a low-voltage communications line. The medium- voltage power line includes a center phase conductor and a concentric neutral conductor. The ground conductor couples the concentric neutral conductor to a ground connection. The one or more ferrites substantially surround at least a portion of the ground conductor. The low-voltage communications line includes a first conductor and a second conductor. The first conductor is coupled to the ground conductor between the one or more ferrites and the concentric neutral conductor. And the second conductor is coupled to the ground
(FR) Dans un mode de réalisation de l'invention, un système destiné à coupler des signaux de communication sur des lignes d'alimentation souterraines de moyenne tension comprend une ligne d'alimentation de moyenne tension, un conducteur de terre, au moins une ferrite, et une ligne de communication basse tension. La ligne d'alimentation de moyenne tension comprend un conducteur de phase centrale et un conducteur neutre concentrique. Le conducteur de terre couple le conducteur neutre concentrique à une connexion de terre. La ferrite entoure sensiblement au moins une partie du conducteur de terre. La ligne de communication basse tension comprend un premier conducteur et un second conducteur. Le premier conducteur est relié au conducteur de terre entre la ferrite et le conducteur neutre concentrique. Le second conducteur est relié à la terre.
