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 housing having a width no larger than a single pole circuit breaker width, the housing 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 current sensor;
- a voltage sensor;
- a wireless radio;
- a memory having instructions stored therein;
- a processor in electrical communication with the circuit interrupter, the current sensor, the wireless radio, and the memory;
- a sensor mount having a clip portion, the clip portion configured to secure the sensor mount to the conductive path;
- and
- shielding material configured to provide magnetic isolation between the current sensor 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 current and voltage information from the current sensor and the voltage sensor and to control the wireless radio to communicate the current and voltage information to the remote device.
