CA 2490620

The invention relates to a method for inputting an information signal into a power cable which is connected to a voltage supply and which comprises at least one or more conductors, a dielectric provided around the conductors and a conductive earth sheath arranged wholly or partially around the dielectric, the method comprising of inputting a pulse-like information signal at a first position via the earth sheath in order to produce a corresponding pulse-like information signal which is propagated to a second position in the dielectric of the power cable.

La pr~sente invention concerne un proc~d~ pour entrer un signal d'informations dans un c~ble ~lectrique qui est reli~ ~ une alimentation en tension et qui comprend au moins un conducteur, un di~lectrique, situ~ autour des conducteurs et une gaine de mise ~ la terre conductrice, plac~e totalement ou partiellement autour du di~lectrique. Ce proc~d~ consiste ~ entrer un signal d'informations de type impulsion ~ une premi­re position, par l'interm~diaire de la gaine de mise ~ la terre, afin de produire un signal d'informations de type impulsion correspondant, qui est transmis ~ une seconde position dans le di~lectrique du c~ble ~lectrique.
