Patent

CA 2278843

A power line communications network carries power and communications signals over power lines. Fitted in the power line is a fuse unit (300) which has means for coupling communications signals to and/or from the power line. The fuse unit may include a high-pass filter. The fuse unit (300) is adapted to mate with an existing fuse socket in the power line to replace an existing fuse, thereby minimising disruption and simplifying installation. The fuse unit can also include means for impeding flow of non-power signals along the line.

L'invention concerne un réseau de communication sur lignes électriques qui achemine des signaux de communication sur des lignes électriques. On installe sur la ligne électrique un bloc fusibles (300) équipé d'un moyen de couplage des signaux de communication à destination et/ou en provenance de la ligne électrique. Le bloc fusibles (300) peut inclure un filtre passe-haut; il est adapté pour s'adapter sur une douille de fusible existante sur la ligne électrique en vue de remplacer un fusible existant, ce qui réduit au minimum les pannes et simplifie l'installation. Le bloc fusibles peut également inclure un moyen pour empêcher la circulation de signaux non électriques sur la ligne.
