Methods and Systems for Continuous Calibration of Circuit Breaker Trip Units and Metering Devices

A computer-based method, wherein said method is performed by a networked computing device, the networked computing device including a processor and a memory device coupled to the processor, the networked computing device in communication with a main trip unit and a plurality of circuit breaker trip units, the main trip unit configured to monitor current associated with a main tripping device, the plurality of circuit breaker trip units configured to monitor current associated with a plurality of circuit breaker tripping devices, said method including:

• requesting and receiving, from the circuit breaker trip units, circuit breaker current data representing current data associated with the circuit breaker trip units over a collection interval;
• receiving, from the main trip unit, main current data representing current data associated with the main tripping device during the collection interval;
• determining a plurality of calibration factors associated with the circuit breaker trip units based upon the circuit breaker current data and the main current data, the calibration factors representing variance between circuit breaker current data associated with a particular circuit breaker trip unit and a derived current associated with the particular circuit breaker trip unit;
• and
• transmitting the calibration factors to the circuit breaker trip units.
