  • 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.
