Abstract
Devices, systems, and methods for measurement of parameters of electric power transmission lines can improve electric power usage, while wireless circuitry can provide communication from field-located devices. Connection to draw electrical power from the transmission line can be distinct from connection to sense line parameters.
Claims21
An on-line measurement system for measurement and communication of transmission parameters of a transmission line, the system comprising:
- a measurement platform adapted for connection with the transmission line for measurement of one or more transmission parameters, the measurement platform including at least one sensor adapted for communication with the transmission line to sense one or more parameters of the transmission line;
- a monitoring bank arranged in communication with the measurement platform to receive indications of the one or more parameters of the transmission line, the monitoring bank including at least one processor and communication circuitry, the at least one processor adapted to execute instructions to communicate indications of the one or more parameters of the transmission line to users via the communication circuitry;
- and
- an energy management system adapted for connection with the transmission line for collecting and managing energy for operation of the on-line measurement system, the energy management system including a capacitive voltage divider bank having a plurality of serially connected capacitors, one capacitor of the plurality adapted for communication with the transmission line to receive a transmission line voltage and another capacitor of the plurality connected to provide an output voltage lower than the transmission line voltage.
