Inductive reactors can help to raise the voltage by introducing a voltage drop in the circuit, which can be useful in cases where the voltage is too high. Conversely, capacitive reactors can lower the voltage by absorbing reactive power and reducing the voltage levels.
Shunt reactors are connected in parallel with capacitors to limit the overvoltage that can occur due to the resonance between the reactive power sources. They help maintain the stability of the system.
When a capacitor bank is a switch on in uncharged condition there may be a high inrush current flowing through it.
