摘要： A current transformer includes first and second bobbins, and a secondary winding. The first bobbin includes a first tube defining a first longitudinal axis. First and second flanges are disposed on first and second ends of the first tube. The first tube, the first and second flanges collectively define a first slit along the first longitudinal axis. The first slit allows receipt of a primary conductor into the first tube. The second bobbin includes a second tube rotatably received about the first tube. The second tube defines a second slit along the second longitudinal axis. The second slit allows receipt of the primary conductor into the first and second tubes. The secondary winding is wound about the first bobbin and extends along the first longitudinal axis, passing through the first tube and over the first and second flanges. The second tube rotates about the second longitudinal axis relative to the first tube.

摘要： A method for delivering a communication signal is disclosed. The method includes receiving, at an optical transceiver, an optical communication and constructing, at a baseband integrated circuit in communication with the optical transceiver, a radio frequency communication (e.g., the intermediate frequency data and control signals) based on the optical communication. The method also includes transmitting the radio frequency communication from a Sommerfeld-Goubau launcher in communication with the baseband integrated circuit as a surface wave along a power line to a strand mount device disposed on the power line. The strand mount device is configured to receive the radio frequency communication and wirelessly transmit the radio frequency communication (e.g., via a wireless link) to a user device.
