Abstract :
The conventional definition for power measurement becomes contentious under nonsinusoidal conditions. This paper discusses the measurement principle and error analysis of induction watt-hour meter in the cases of non-harmonics and a variety of harmonics. In contrast with non-harmonics, the measuring process and the complexity of the measurement errors are analyzed under nonsinusoidal conditions. Then, the laws of measurement errors are summed up and a model of power measurement is proposed.
