Keywords: Root mean square, Simulation, Digital filtration, Measuremen

Abstract: – Currently, the measurement method of root mean square value (RMS), based on the averaging of the squares of samples, is the most popular. The advantages of this method include ease of implementation, high accuracy and additional opportunities to reduce the methodological component of the measurement error. Studies show that increasing measurement time also contributes to a reduction in error. However, in a number of measurement and automatic control problems, one of the main requirements is to reduce the measurement time. This problem can be solved by a method based on moving averaging, which includes the advantages of the “classical” method, but is largely devoid of its shortcomings. The article outlines the basic principles of the RMS measurement method based on moving averaging. An algorithm for its implementation on the basis of recursive and non-recursive moving average filters is proposed. The influence of the sinusoidal signal parameters on the RMS measurement error is analyz
