Protection of Pilot-Wire Circuits
Transactions of the American Institute of Electrical Engineers, 1942THIS paper reviews the problem of protecting pilot-wire circuits, briefly discusses the sources of disturbing voltages, describes two types of neutralizing transformers, and illustrates how they are used to distribute the disturbing voltage most favorably throughout the pilot-wire circuit.

Electrical Engineering, 1935
Recent developments in relay protective schemes, using metallic pilot channels for isolating a transmission line during fault conditions, reduce conditions, considerably the magnitude of the currents which must be handled. Schemes recently developed have many other advantages over the older pilot wire schemes being more economical to install and ...

Pilot protection communication channel requirements
57th Annual Conference for Protective Relay Engineers, 2004, 2004Pilot relaying has been applied for transmission line protection since the 30's. The well known communication channels (pilot wire or power line carrier) are increasingly being replaced by digital channels. Dark fiber (dedicated fiber optic cable), multiplexed fiber optic systems (T1 and SONET) and 56 kbps phone lines (DDS - digital data service) are ...

Protection of Pilot Wires From Induced Potentials
Transactions of the American Institute of Electrical Engineers, 1946The use of pilot-wire relays for protection of power transmission circuits usually requires a reliable pilot channel which is free of any induced potentials Which may cause transient voltages to appear between wires even though they may be of relatively low magnitude.
