Abstract: Techniques for generating simulated waveforms for an electric meter include operating a meter in simulation mode without an external load device connected to the meter. Simulated waveforms are generated for a number of channels based on waveform component values. The waveforms are generated at a rate that corresponds to a sample rate of an analog to digital converter (ADC) of the meter. In simulation mode, the waveforms are provided to a meter firmware interface, instead of the waveform data obtained from the ADC.

Abstract: A utility meter includes a meter housing in which are supported at least one current coil, a temperature sensor, and a processing circuit. The current coil can be coupled to receive heat energy from within or on the meter socket. The temperature sensor generates a sensor signal based on a temperature within the meter housing. The processing circuit is operably coupled to the temperature sensor and the at least one current coil. The processing circuit obtains the sensor signal and generates temperature information therefrom, and also generates measurements of current through the current coil. The processing circuit generates an adjustment based at least on the square of the measured current, and determines whether an abnormal condition exists based on the temperature information, the adjustment, and a threshold. The processing circuit can generate an output signal to a display or communication circuit responsive to determining that the abnormal condition exists.

Abstract: A power measurer measures, for each current transformer CT, electric energy supplied to equipment or electric energy supplied from the equipment based on a current measured by a current measurer and a voltage measured by a voltage measurer. A sign memory stores, for each current transformer CT, information indicating whether the electric energy measured by the power measurer when the current transformer CT is disposed in a correct direction on a power line shows a positive sign or a negative sign. A determiner determines that, when the sign stored in the sign memory differs from the sign of the electric energy measured by the power measurer, the current transformer CT is disposed in an incorrect direction on the power line.

Abstract: Described herein are methods and systems for identifying individual branch circuits coupled to a power distribution point. A sensor module positioned in proximity to the power distribution point and having a plurality of magnetic field sensors senses a magnetic field emitted by each of a plurality of branch circuits coupled to the power distribution point. A processor coupled to the sensor module determines a response of each magnetic field sensor to each of a plurality of changes in power associated with at least one of the plurality of branch circuits. The processor positions the responses of the magnetic field sensors to each change in power on a point in a multidimensional space, where each dimension of the multidimensional space corresponds to a magnetic field sensor. The processor identifies clusters of the points in the multidimensional space, each cluster representing a different branch circuit and having a different vector direction.
