Abstract
An electric power meter for measuring electric power is provided. The power meter has a frequency domain converter arranged to convert a sequence of digital voltage samples from the time domain to a frequency domain obtaining digital voltage frequency components, and to convert a sequence of digital current samples from the time domain to the frequency domain obtaining digital current frequency components. The electric power meter also has a frequency domain correction unit arranged to correct the voltage frequency components and the current frequency components by multiplying at least one frequency component of the current frequency components and the voltage frequency components with a complex correction factor using a complex multiplication unit. Electric power is computed by an energy calculation unit.
