Abstract
A circuit apparatus measures, records, transmits, and displays actual and estimated power consumption in a branch circuit of an electrical distribution system. The apparatus includes a display driver coupled to one or more current sensors which derives or estimates power consumption from measured current. The accuracy of power consumption is improved by additional measurement of actual supplied voltage. A plurality of current sensors determine differential current to provide ground fault interruption to a desired range of precision. A store enables display of surge and average current measurements and power measurements in addition to immediate results.
Claims10
A power consumption monitoring apparatus compatible with replaceable panel circuit breakers, the apparatus comprising:
- a display;
- the display coupled to,
- a display driver;
- the display driver coupled to,
- a current sensor, the current sensor coupled to,
- a conventional overcurrent circuit interrupter, the conventional overcurrent circuit interruptor having,
- a sensor/actuator mechanism;
- coupled to,
- a resistive mass through which current flows in normal operation and provides a measurable voltage drop to the current sensor.
