Abstract: The present disclosure relates to a system for automatically identifying product information, including a lamp information collection module, a controller, and a user terminal. The controller has a built-in comparison table setting different power information intervals for different lamp categories, and sends to-be-collected power information to the lamp information collection module. The lamp information collection module is used to collect corresponding power information according to the received to-be-collected power information and send the collected power information to the controller. The controller is further used to determine a category of a lamp according to the collected power information corresponding to the lamp and the power information interval comparison table, and send information of the lamp to the user terminal. The user terminal includes a human-machine interface and is used to display the information of the lamp on the human-machine interface.

Abstract: 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.

Abstract: An electrical panel or an electrical meter may provide improved functionality by interacting with a smart plug. A smart plug may provide a smart-plug power monitoring signal that includes information about power consumption of devices connected to the smart plug. The smart-plug 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 plug, (ii) identify devices receiving power from the smart plug, (iii) improve the accuracy of identifying device state changes, and (iv) train mathematical models for identifying devices and device state changes.

Abstract: A decoupled ETP model processor is configured to store power consumption data retrieved from power systems; convert the power consumption data into power activated time cycles and power non-activated time cycles; derive a thermal resistance (R) parameter and a capacitance (C) parameter for a predetermined heat flow (Q) parameter at each of the outdoor temperatures; compare the converted power activated time cycles to the actual power activated time cycles; compare the converted power non-activated time cycles to the actual power non-activated time cycles; calculate a first improved resistance-capacitance-heat flow (RCQ) parameter set and a respective first outdoor temperature for the compared and converted power activated time cycles to the actual power activated time cycles; calculate the Q parameter at each outdoor temperature during the power activated time cycles; and calculate the R parameter and the C parameter at each outdoor temperature during the power non-activated time cycles.

Abstract: Provided is a sensor in which a current sensor that detects a current of a power line as a change in a magnetic field and a voltage sensor that detects a voltage of the power line using capacitive coupling are integrally formed. The transmission of signals related to substantially the same sections is omitted in order to effectively compress an output signal from the sensor and an output signal from the voltage sensor. When the amplitude and phase of a fundamental wave which are estimated from the output signal from the sensor and the amplitude and phase of harmonics are encoded, the amplitude and phase of the harmonics are relativized with a value for the fundamental wave.

Abstract: An electricity meter includes a power line interface circuit configured to generate measurements of parameters for at least two electricity transmission paths. The meter also includes a balance determination circuit configured to generate at least one balance metric that indicates a balance between the electricity transmission paths from the generated measurements. The meter further includes a communications circuit configured to transmit balance information to an external recipient responsive to the at least one balance metric.

Abstract: Sampling timings at a plurality of measurement points at which waveform data of a power line is sampled are easily synchronized to each other. A measurement device includes: a sampling unit configured to sample a waveform of at least one of a voltage and a current at a measurement point of a power line at a predetermined sampling timing; a processing unit configured to execute processing of the waveform sampled by the sampling unit; a time information acquisition unit configured to acquire time information from a time information provision device that is communicatively connected through a network; and an adjustment unit configured to adjust a processing timing of the processing on the basis of the time information acquired by the time information acquisition unit.

Abstract: A method of detecting conditions indicative of energy meter tampering, meter faults or energy loss (e.g. due to energy theft) is disclosed. The method includes receiving energy consumption data from an energy meter indicating consumption of energy at a location served by the energy meter. Event data is also received from the meter comprising one or more events generated by the energy meter. The consumption data is analysed to detect a predetermined consumption condition. The event data is analysed to detect a predetermined event or event pattern in the event data. An alert condition is generated in response to detecting both the consumption condition and the event or event pattern.
