Abstract :
This paper deals with error compensation in power metering introduced by current and voltage transformers. The ratio correction factors, RCF, are determined for each harmonic level using either the equivalent circuit model or direct measurements. Fourier based metering is then utilized to compensate for the error at each harmonic level.
