A smart circuit breaker may provide a smart-circuit-breaker power monitoring signal that includes information about power consumption of devices connected to the smart circuit breaker. The smart-circuit-breaker power monitoring signal may be used in conjunction with power monitoring signals from the electrical mains of the building for providing information about the operation of devices in the building. For example, the power monitoring signals may be used to (i) determine the main of the house that provides power to the smart circuit breaker, (ii) identify devices receiving power from the smart circuit breaker, (iii) improve the accuracy of identifying device state changes, and (iv) train mathematical models for identifying devices and device state changes.

A utility meter includes a consumption measurement unit for generating consumption data, a meter processor, and a RTC for time stamping the consumption data to provide interval meter data during interval meter operation. A memory stores the interval meter data. The meter processor implements/initiates responsive to a power loss that suspends RTC operation, switching from interval to relative time operation where consumption data is stored as relative consumption data together with a relative time as relative meter data. Responsive power restoration and receiving a current time, the meter switches from relative time to interval meter operation. The restoration time is calculated using the current and an elapsed time since the restoration. The time of restoration and current time is used to generate calculated times. The consumption data from relative time operation is time stamped with the calculated times to provide time-corrected relative meter data that is stored to the memory.

Power estimation method, implemented in a three-phase electricity meter, includes the steps of detecting a fraud which falsifies measurements of a first phase voltage present on a first phase, without falsifying measurements of a second phase voltage present on a second phase; reconstituting first estimated voltage samples, images over time of the first phase voltage, from second voltage samples, images over time of the second phase voltage; and estimating at least one first electrical power consumed on the first phase by using the first estimated voltage samples.

Non-intrusive monitoring and workflow assessment to optimize manufacturing environments are described herein. The systems and method combines computer vision and energy load disaggregation to track worker activity and equipment usage and status. These events are then correlated to optimize workflows and energy efficiency.
