G01R 21/133

US Classification:

702 61, 702 85

Abstract:

Some embodiments can teach a system for monitoring usage of electrical power by a structure. The structure can have one or more main electrical power lines that supply the electrical power to a first load in the structure. A portion of the one or more main electrical power lines can run substantially parallel to a first axis. The structure can further have a panel that overlies the portion of the one or more main electrical power lines. The system can include: (a) a current sensor unit configured to be coupled to a portion of a surface of the panel, the current sensor unit having: (a) at least one magnetic field sensor having a length substantially parallel to a second axis, wherein the second axis is substantially perpendicular to the first axis, and the at least one magnetic field sensor is configured to detect a magnetic field generated by the one or more main electrical power lines; and (b) a processing unit configured to run on a processor. The current sensor unit can be configured to produce an output signal based on the magnetic field detected by the at least one magnetic field sensor. The processing unit further can be configured to receive the output signal from the current sensor unit and process the output signal to determine one or more parameters related to the usage of the electrical power by the first load in the structure. Other embodiments are disclosed.

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.
