POWER LINE COMMUNICATION AND POWER DISTRIBUTION PARAMETER MEASUREMENT SYSTEM AND METHOD

摘要

A power line communication device is provided that in one embodiment includes a parameter sensor device configured to measure a parameter of a power line, a modem configured to transmit parameter data over a power line, and a controller communicatively coupled to the current sensor device and modem. The parameter sensor device may include a current sensor device that includes a Rogowski coil. For measuring the current or other parameter of a higher voltage power line conductor, the parameter sensor device may be configured to provide data to the controller via a non-conductive communication link, such as via a wireless, fiber optic, or radio frequency transponder link. In addition, the parameter sensor device may include an isolated power source and receive power via a fiber optic conductor or inductively from the power line.
