VOLTAGE AND REACTIVE POWER CONTROL DEVICE Russian patent published in 1994 - IPC

FIELD: electric power distribution systems. SUBSTANCE: device is provided with potential regulator connected to secondary winding of transformer-reactor; capacitor bank is connected to point of connection of primary and secondary windings of potential regulator and to starting lead of secondary winding of transformer-reactor; inductive reactance of potential regulator primary winding must be equal to capacitive reactance of capacitor bank. Varying angle of magnetic coupling between primary and secondary windings of potential regulator changes current in secondary winding of transformer-reactor and, consequently, equivalent resistance of transformer-reactor primary winding. EFFECT: improved reliability of control. 1 dwg
