Many electrical devices draw high currents at startup or have very low impedance to the flow of current. For example, electric motors typically draw many times their full-load current during startup. This inrush current can cause voltage sags that trip out other equipment. Many full-voltage motor starters use reactors to.

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.
A reactor is a coil with a large number of turns and high ohmic resistance. Its primary purpose is to limit the short circuit currents that can potentially damage power system equipment. Reactors are added in series with the system to provide additional reactance for protection.
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.
A reactor, also known as a line reactor, is a coil wired in series between two points in a power system to minimize inrush current, voltage notching effects, and voltage spikes. Reactors may be tapped so that the voltage across them can be changed to compensate for a change in the load that the motor is starting.
