J. Driesen et al., THE REGISTRATION OF HARMONIC POWER BY ANALOG AND DIGITAL POWER METERS, IEEE transactions on instrumentation and measurement, 47(1), 1998, pp. 195-198
This paper discusses the measurement error of energy meters operating
under harmonic distortion. A system to determine the magnitude of the
error caused by an individual harmonic is used to generate curves on w
hich the error introduced by different frequency components is display
ed, An algorithm using these data to predict the resulting measurement
error of a linearly operating energy meter registering under circumst
ances of any known harmonics in the voltage and the current is present
