Abstract. We propose a method to determine the root-mean-square (RMS) value of the harmonic process in real time, which is based on the principle of phase tracking signal corresponding to the instantaneous value of the process, it is numerically equal to the RMS. The features of the method, the error arising from its application, as well as the possibility to simplify the algorithmic and developed hardware devices are considered.

Key words: root-mean-square value, time interval, phase, measurement, error.
