What is the Purpose of Reactors?/What are Filter Reactors Used for?

Reactors, also known as inductors or chokes, are devices that are used to limit the flow of alternating current (AC) in electrical systems. They are used for a variety of purposes, such as to filter out high-frequency noise or to smooth out power supply voltages.

One common type of reactor is the filter reactor. These devices are used in electrical power systems to reduce harmonic distortion caused by non-linear loads. Non-linear loads are devices that do not have a linear relationship between the input voltage and current. Examples of non-linear loads include power electronics such as variable speed drives, rectifiers, and switch-mode power supplies.

Filter reactors work by introducing a high impedance to the flow of harmonic currents, which helps to prevent the harmonic currents from flowing back into the power system. This reduces the amount of harmonic distortion in the power system, which can help to improve the quality of power and prevent damage to equipment.

Another type of reactor is the shunt reactor, which is used to compensate for capacitive reactive power in long transmission lines. Capacitive reactive power is caused by the capacitance of the transmission lines and can cause voltage instability in the power system. Shunt reactors are connected in parallel with the transmission lines and help to absorb the excess capacitive reactive power, which helps to stabilize the voltage in the power system.

Overall, reactors are important components in electrical power systems that help to ensure the quality and stability of power supply. Filter reactors in particular are essential in reducing harmonic distortion caused by non-linear loads, which can help to prevent damage to equipment and improve the efficiency of power systems.
