FIELD: electricity.
SUBSTANCE: at first one determines amplitude and initial oscillating phase angle of the single-frequency current harmonic and, following the action sequences proposed in the invention, divides the instantaneous value of periodic nonsinusoidal electric voltage by the isolated harmonic amplitude to obtain a new periodic nonsinusoidal main auxiliary signal having resistance dimension which is then multiplied by main auxiliary signal formed according to a specific algorithm. The obtained product of two signals is integrated according to the direct component isolation rule with the integration result used for identification of one of the components of the passive linear bipole complex input resistance.
EFFECT: improved accuracy.
