                      Fig. 6.12 Alternative arangements of three-phase thyristor-switched capacitor. (a) delta-connected secondary,
                      Delta-connected TSC; and (b) wye-connected secondary, wye-connected TSC (four-wire system).





















                      Fig. 6.13 Principles of operation of TSC. Each phase of Figure 6.12 comprises of parallel combinations of
                      switched capacitors of this type.
