Figure 82: TCSC wave forms presented in capacitive boost mode for a typical
50Hz system
The apparent impedance of the TCSC (the impedance seen by the power system) can
typically be increased to up to 3 times the physical impedance of the capacitor, see
figure 83. This high apparent reactance will mainly be used for damping of power
oscillations.
