  • Patent number: 11408920
    Abstract: A system for crosstalk cancelation for electricity metering in a power distribution network is provided. For example, a meter can be used to generate a set of measurement points by measuring electrical signals provided by a reference power device according to a set of source points. Based on the set of source points and the corresponding set of measurement points, a crosstalk cancelation function is derived and stored in the meter. When the meter is deployed at a geographical location and generates a measurement point by measuring the electrical signal on the power distribution network, the meter further applies the crosstalk cancelation function to the measurement point to generate a transformed measurement point. The meter calculates various characteristics of the power distribution network based on the transformed measurement points and transmits the calculated characteristics to a headend system.

  • Patent number: 11313905
    Abstract: An electric meter that is configured to regenerate meter state data after a power loss includes a memory with at least one volatile and non-volatile memory device and a processor connected to the memory. The processor is configured to retrieve a backup copy of meter state data and a plurality of meter input data samples that were generated after the backup copy of the meter state data and prior to the power loss from a nonvolatile memory device. The processor is configured to regenerate meter state data by updating the backup copy of meter state data with the plurality of meter input data samples to regenerate the meter state data at the time of a final meter input data sample prior to the power loss.

  • Patent number: 10816578
    Abstract: An electrical energy meter includes an A/D converter and a processing circuit. The A/D converter is configured to generate digital samples of voltage and current waveforms in a polyphase electrical system. The processing circuit is operably coupled to receive the digital samples from the A/D converter and to integrate over time at least one digital sample multiple times to produce a filtered value from which harmonic distortion has been removed, identify a fundamental frequency only electrical parameter measurement for the polyphase electrical system with reference to the filtered value, and store the identified fundamental frequency only electrical parameter measurement in a data store.
