Abstract:
A power line communications system for communicating over a power line, said system comprising:a plurality of power leads for connecting a first electrical equipment with a second electrical equipment; a first conductor; a second conductor connected to said first conductor and forming a loop, said first conductor and said second conductor forming one of said plurality of power leads; a first current transformer inductively coupled to said loop, said first current transformer defining a first current transformer opening, said first conductor passing through said first current transformer opening, said second conductor passing through said first current transformer opening in an opposite direction with respect to said first conductor, said first current transformer inducing a loop current in said loop; and a second current transformer inductively coupled to said loop, said second current transformer defining a second current transformer opening, said first conductor passing through said second current transformer opening, said second conductor passing through said second current transformer opening in an opposite direction with respect to said first conductor, said second current transformer sensing said loop current in said loop.
