What is a Reactor? Types of Reactors and Their Applications

A reactor is an inductive component used in electrical systems to limit current, reduce harmonics, regulate voltage, and improve overall power quality. Reactors are commonly employed in power distribution, motor drives, and harmonic filtering applications. Depending on their function and installation area, reactors are manufactured in various types.

Common types of reactors include:

• Shunt Reactor: Used in high-voltage transmission systems to absorb reactive power and stabilize voltage levels.

• Harmonic Filter Reactor: Designed to suppress harmonic distortions in electrical networks and optimize the performance of harmonic filter systems.

• Motor Drive Reactor: Installed at the input or output of motor drives to limit voltage spikes, reduce electromagnetic interference (EMI), and protect the motor from electrical stress.

• Line Reactor: Placed in series with power lines to limit short-circuit currents, reduce inrush currents, and contribute to voltage regulation.

The selection of a reactor depends on system parameters such as voltage, current, frequency, and the specific purpose of use. Proper reactor use enhances system protection, energy efficiency, and equipment reliability.
