Abstract :
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 which the error introduced by different frequency components is displayed. An algorithm using these data to predict the resulting measurement error of a linearly operating energy meter registering under circumstances of any known harmonics in the voltage and the current is presented
