FIELD: power engineering. SUBSTANCE: control circuit of adjustable reactive current source is digital device. It has two character sensors, half-adder, integrator is reversing counter. Multiplier has voltage-to-frequency converter coupled through controllable frequency divider and directly with inhibit unit, whose output is connected to second controllable frequency divider, analog-to-digital converter connected to code converter whose outputs are connected to inputs of both controllable frequency dividers. EFFECT: improved measurement accuracy in static and dynamic conditions, improved degree of reactive power correction. 3 dwg
