Flexible alternating current transmission systems (FACTS) application includes several types of reactors: thyristor-controlled shunt reactors (TCR), thyristor-switched reactors (TSR), thyristor-switched capacitor reactors (TSC), thyristor-controlled series capacitor reactors (TCSC), and mechanically switched shunt reactors (MSR).

The collection also comprises converter or phase reactors (STATCOM), harmonic filter reactors, series compensation (SC) damping reactors, and discharge reactors (in the bypass circuit).
