Static capacitors are connected in parallel with the load. They are used for power factor correction with the load. Static capacitor banks use thyristors to switch them ‘ON’ or ‘OFF’. To control dynamic control swings, under various conditions, static capacitors banks are in use.
The difference between a static capacitor and a synchronous capacitor lies in their reaction to reactive power. A synchronous capacitor has the ability to continuously adjust its reactive power, while a static capacitor does not.
