Optical Ground Wire For Communication Between Power Substations

With the advent of modern microprocessor relaying, much of the communication between relays has been shifting from power-line-carrier apparatus or microwave to fiber. Since power utilities own the easements for the high voltage transmission lines, it is only logical to install fiber up there. One ingenious location is the lightning shield wire. It is the …
