  • System and method for digitally compensating frequency and temperature induced errors in amplitude and phase shift in current sensing of electronic energy meters
    Patent number: 6618684
    Abstract: The phase shift in an electronic energy meter is compensated for by obtaining temperature and frequency readings in the meter and using these readings in a digital signal processor (DSP) residing within the electronic energy meter. The frequency and temperature compensation is performed to each phase calibration and the result is stored in the DSP. To reduce the possible influence of noise in the system, the compensated DSP values are filtered to provide a smoothing of the data.
