Abstract
The method of frequency transformations measurement for digital power of electrical signals meters is offered. The method is based on instantaneous power correlation processing. Such approach allows increasing noise immunity of the proposed method, and, as a consequence, its accuracy. Proposed mathematical theory to estimate the variance measurement error of the power of electrical signals. Proposals have been made to reduce the error in measuring the power of electrical signals. The analysis of the interference immunity of the correlation method for measuring power can be extended to the condition under which the interference spectra in voltage and current signals are different.
