Patent ID: 7312694

Claim:
A device for coupling a signal onto an elongated conductor of an electrical power delivery system, the device comprising: an elongated conductive member having a length of at least six inches but less than 200 feet, said elongated conductive member adapted to be positioned in parallel with the elongated conductor; an insulator adapted to be positioned between the elongated conductive member and the elongated conductor along the length of the elongated conductive member such that the insulator separates the elongated conductor and the elongated conductive member along the length of the elongated conductive member and such that the elongated conductive member is capacitively coupled along its length to the elongated conductor; and a data signal generator adapted to be connected to the elongated conductive member for supplying a data signal to the elongated conductive member; wherein the elongated conductive member is adapted to capacitively couple the data signal onto the elongated conductor.
