Abstract
The principles of functioning of the specialized multiphase Electrical Power Standard (EPS) combined with the measuring instrument (MI) of parameters of signals of electric networks controlled by the general microcontroller are offered and analyzed. Methods and algorithms of correction of parameters of output signals of EPS by taking into account results of measurement of the specified parameters in MI are developed and investigated. An equivalent correction scheme of n-th harmonic is proposed. References 20, figures 5.
