  • Patent number: 11175322
    Abstract: Certain aspects and features include a system and method for energy measurement in electric meter systems. In an example, an electric meter receives an Alternating Current (A/C) signal. The electric meter includes a current measurement device that is configured to obtain a current measurement of a current of the A/C signal. The current measurement includes a fundamental frequency component and a noise component. The electric meter receives a current measurement signal from the current measurement device and filters the noise component from the current measurement, thereby creating a filtered current measurement signal. When the filtered current measurement signal is greater than a starting current threshold, the electric meter calculates an energy consumption measurement.

  • Patent number: 11092654
    Abstract: The systems determine the parasitic capacitance of a signal path. That parasitic capacitance is then used to determine a leakage characteristic of the signal path, such as leakage current or leakage resistance. The capability of ATE channels to force current accurately, and to measure time intervals at prescribed voltages, can be used to multiply the accuracy of the force current function. Using these resources, small leakage currents—for example, on the order of 10 nA or less—can be measured.
