Controllable shunting reactor of transformer type

The development of controllable reactors is associated with the introduction of long-range superhigh-voltage electrical transmission. The excess reactive power of relatively short (up to 300m) high-voltage above-ground lines may be absorbed by power-station generators. Increasing the voltage to 400-500kV or more and increasing the length of the line entails the creation of special devices for absorbing the excess reactive power of the line with the transmission of power P considerably less than the rated power P r . This implies the need to develop controllable shunting reactors (CSR).
