Patent ID: 10345423

Abstract:
A system for monitoring electrical power usage in an electrical power infrastructure of a building. The system can include: a power consumption measurement device configured to be coupled to a first surface of the circuit breaker box, the circuit breaker box containing at least part of the electrical supply conductors for the electrical power infrastructure, the power consumption measurement device comprising one or more electrical current sensors; a first calibration device configured to be electrically coupled to the electrical power infrastructure, the first calibration device comprising one or more first calibration loads; and a calibration module configured to be performed using one or more processors and further configured to at least partially calibrate the power consumption measurement device using a Kalman filter and data obtained from the one or more electrical current sensors of the power consumption measurement device. The power consumption measurement device is configured to obtain at least part of the data while at least one of the one or more first calibration loads is electrically coupled to the electrical power infrastructure and while the power consumption measurement device is coupled to the first surface of the circuit breaker box. Other embodiments are provided.
