发明名称 Electric energy meter for an AC mains supply
摘要 An energy consumption meter having a variable phase error compensator. While the variable phase error compensator may provide fixed phase error compensation for fixed phase error(s), it may also provide variable compensation for varying phase error(s) introduced by one or more parameters. Varying phase error(s) may be introduced, for example, by fluctuations in the frequency of an alternating current supply. Such varying phase errors may be corrected by monitoring one or more sources of varying phase error(s), calculating one or more appropriate corrections, and correcting one or more sampled parameters involved in determining energy consumption. This avoids erroneous energy consumption metering due to varying phase errors.
