  • Publication number: 20230094412
    Abstract: A system and method for phase and gain calibration of a current sensor system. The system comprises a microcontroller configured to execute software in an energy measurement component and a calibration computer having a calibration application. The energy measurement component receives first and second digital signals representing current and voltage signals, respectively, received from a test source, and calculates active power and a power factor, and provides those values to the calibration computer. The power factor is converted to a converted phase angle. Based on the information received from the energy measurement component, the calibration application calculates parameters used to update components within the microcontroller to maximize the accuracy of the current sensor system.
