Investigate a new method for measuring the integral characteristics for instant values of harmonic signals. The method is based on the formation of the orthogonal component  of the input voltage and the comparison voltage, and an additional signal. Method allows you to start the measurement process at any given time. The results of the analysis of measurement errors of the signal parameters due to the deviation of the real signal from the harmonic model are examined.
