Abstract
A power line coupler for communicating data signals over a power distribution system having a first and second overhead energized medium voltage power line conductors is provided. In one embodiment, the coupler includes a first lightening arrestor having a first end and a second end, wherein the first end of the first arrestor is connected to the first power line conductor. The coupler further includes a first high frequency impedance having a first end connected to the second end of the first lightening arrestor and the first impedance having a second end connected to a neutral conductor of the power line distribution system. The coupler may further include a second lightening arrestor having a first end and a second end, wherein the first end of the second arrestor is connected to the second power line conductor. The coupler further including a second high frequency impedance having a first end connected to the second end of the second lightening arrestor and a second end connected to the neutral conductor. The first high frequency impedance and the second high frequency impedance may each comprise an air core coil that forms an inductor. The coupler may further include a balun having a first winding and a second winding, wherein the first winding is coupled to a communication device, and wherein the second winding has a first end connected to the first end of the first high frequency impedance and a second end connected to the first end of the second high frequency impedance.
