Abstract
Communication enabled circuit breakers are described. Methods associated with such communication enabled circuit breakers are also described. The communication enabled circuit breakers may include one or more current sensors. The one or more current sensors may be disposed in a clip. The clip may be coupled to a line side phase connection, and the clip may be shielded to attenuate signals.
Claims23
A communicating circuit breaker for measuring and transmitting information related to power quality and metering data to a remote device, the communicating circuit breaker comprising:
- a line side phase connection;
- a load side phase connection;
- a conductive path configured to be selectively coupled between the line side phase connection and the load side phase connection;
- a circuit interrupter configured to selectively couple the conductive path;
- a Rogow ski coil;
- a wireless radio;
- a memory having instructions stored therein;
- a processor in electrical communication with the circuit interrupter, the Rogowski coil, the wireless radio, and the memory;
- a sensor mount having a body portion and a clip portion, the body portion having a cavity configured to receive the Rogowski coil, the clip portion configured to secure the sensor mount to the conductive path;
- and
- shielding material configured to provide magnetic isolation between the Rogowski coil and one or more of the circuit interrupter, the processor, the memory, or the wireless radio,
- wherein the processor is configured to execute the instructions stored in the memory to collect information from the Rogowski coil and to control the wireless radio to communicate the information to the remote device.
A circuit breaker, comprising:
- a line side phase connection;
- a load side phase connection coupled to the line side phase connection;
- a fault interrupter configured to interrupt a current flow between the line side phase connection and the load side phase connection;
- a current sensor arranged proximate to the line side phase connection, the current sensor configured to measure a current;
- and
- a wireless radio coupled to the current sensor, the wireless radio to receive a signal from the current sensor to include an indication of the current measured by the current sensor and to send an information element including an indication of the current measured by the current sensor to a breaker controller.
A circuit breaker, comprising:
- first and second line side phase connections;
- first and second load side phase connections;
- a fault interrupter configured to interrupt a current flow between the first and second line side phase connections and a current flow between the first and second load side phase connections;
- a first shielded current sensor arranged proximate to the first line side phase connection, the first shielded current sensor configured to measure a current in the first line side phase connection;
- and
- a second shielded current sensor arranged proximate to the second line side phase connection, the second shielded current sensor configured to measure a current in the second line side phase connection.
