How does a capacitor increase current ow through a thyristor?

The capacitor will then discharge through the thyristors and the reactor. The effect of this is that the capacitor will appear to be smaller, i.e., it will have a higher impedance. This increases the apparent degree of series compensation for the line thereby boosting the current ow through the line.
