  • Patent number: 5592354
    Abstract: An apparatus for enabling pilot wire relays to communicate across voice-grade, non-metallic communication channels converts sinusoid signals representative of phase currents at a location in an electric power distribution system to audio band signals representative of the phase of the current signal at that location. These audio band signals are transmitted over a voice-grade non-metallic communication channel to a remote interface module where they are converted to square waves which are compared against square waves representative of the currents in the electrical power distribution system at that location.

  • Patent number: 5426554
    Abstract: In a pilot wire relay electrical power distribution protection system, an audio band interface apparatus acquires a Hz pilot wire signal from the pilot wire relay and produces signals having frequencies within the frequency band pass of fibre optic communication channels. The apparatus enables pilot relays, which previously communicated over hard wire connections such as dedicated telephone lines, to communicate through a fibre optic communication channel without the necessity for extensive modifications to the pilot wire relay.
