Abstract
Presented method of digital determination of voltage of a zero phase-sequence of the three-phase system of voltages uses the following steps: tuning the frequency of reading (aliquot 3) instantaneous values of phase voltages to the network’s fundamental frequency; analog-digital conversion of instantaneous values of network’s three phase voltages; selection of codes containing the desired symmetric sequence; selection of fundamental frequency voltage’s codes. This method is simpler and more precise comparing to those well-known. References 4.
