FIELD: electrical engineering.
SUBSTANCE: according to the method, the current and voltage of the supply electrical network are measured. The signal proportional to the voltage is shifted in phase, and rectangular pulses are formed from this signal. The pulse signal is multiplied by a signal proportional to the current. The output signal from the multiplication unit is supplied to the input of the integrator forming a signal for the actuating apparatus. Additionally, the active r and inductive x resistances of the supply electrical network are measured and the phase shift of the signal proportional to the voltage is set as
EFFECT: increase in the quality of electricity and the reliability of operation of the electrical equipment.
