A large number of harmonics generated by nonlinear loads injected into the grid will make the power system voltage and current waveforms produce a serious distortion, in turn impact on the measuring instrument. Harmonic generation because and it’s impact on induction watt-hour meter are introduced in this paper, the measurement error on the induction meter is analized, and methods and countermeasures to reduce the induction meter power measurement error are proposed.
Analysis and compensation of active power measurement error caused by non-integer period sampling
