Abstract :
This paper describes the basic approach taken in designing special SSB power line carrier equipment using baseband injection for the protection of AEP´s 765-kV lines, and the unusual means for coupling these PLC signals to the transmission system in a most efficient and reliable manner through a three phase connection. Attenuation and impedance data measured with the coupling equipment connected to a 200 mile long line are included.
