Power line coupling device and method of use |
摘要 |
The coupler of the present invention couples data signals, such as broadband RF signals, to and from a power line. The coupler of one embodiment that is for use with overhead power lines includes a length of URD MV cable with the neutral conductor removed. Each end of the URD cable is communicatively coupled to the MV power line conductor a predetermined distance from other. The distance between the two connections points on the MV may be related to the wavelength of a carrier frequency used to communicate the data signals. The URD cable may also form part of a transformer to permit the passage of data signals while preventing the flow of the high voltage power signals through the coupler. The neutral semi-conductive jacket of the URD cable may be coupled to ground via a low frequency conductive path.
