FIELD: electrical engineering. SUBSTANCE: current-limiting device and reactive-power source built around controlled reactors and capacitor banks are controlled by means of programmable controller; controlled valves of thyristor reactive-power source are star-connected and run to electrical network phase leads via reactor control winding which are connected in series with capacitor banks, the latter being connected to phase of uncontrolled rectifier loaded into reactor magnetizing windings and resistor. EFFECT: enlarged functional capabilities. 3 dwg
