FIELD: electricity.
SUBSTANCE: instantaneous values of voltage and current signals are measured in load mode at the end of line for the same instants of time with discreteness of arrays of instantaneous values. Signals are transmitted from the end of line to its beginning via communication channel. Pairs of digital readouts are stored as current ones. Then, arrays of instantaneous values of total voltage and current are shaped at the same time. As per those arrays there determined are active and reactive powers, and as per arrays of instantaneous values of total current there determined is actual current. At the same time there determined are active and inductive resistances which are parameters of longitudinal branch of equivalent circuit. Then, there determined are losses of active and reactive powers, as well as values of active and reactive powers in longitudinal branches of equivalent circuit. Then, considering certain values of power and current, there determined at the same time are active and capacitive conductances which are parameters of transverse branch of equivalent circuit.
EFFECT: improving accuracy.
