A series reactor is an electrical device that is connected in series with a circuit or system. It is primarily used to control and limit the flow of electrical current. Series reactors are commonly employed in power systems for various reasons, including improving power quality, protecting equipment, and enhancing system stability.

Note: We also provide capacitor as per customer / system requirements.
In certain situations, especially when dealing with power systems with a high level of harmonics or resonance issues, a detuning reactor is added to the capacitor bank.The detuning reactor is connected in series with the capacitors. Its primary purpose is to reduce or eliminate the risk of resonance in the system. There are 2 type of reactor one is tuned reactor and other is detune reactor.
The combination of capacitors and reactors forms a tuned filter circuit. The capacitors provide reactive power support, and the reactors prevent resonance. Resonance can occur when the natural frequency of the capacitor bank matches the frequency of harmonics present in the system. Resonance can lead to increased currents and voltages, potentially causing equipment damage.
Detuning reactors are designed to provide inductive reactance. This inductive reactance, when added to the capacitive reactance of the capacitors, helps to shift the natural frequency of the circuit away from the system harmonics. By detuning the circuit, the risk of resonance is minimized, and the overall stability of the power system is improved.
