ABSTRACT:
The invention relates to a method for inputting an information signal into a power cable which is connected to a voltage supply and which includes 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 incluging 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.
