Function of reactor

Capacitance effect on light no-load or light load lines to reduce power frequency transient overvoltage.

Reactors, also known as inductors, are widely used in circuits. Because of electromagnetic induction, there is a certain inductance in the circuit, which can prevent the change of current. When a conductor is charged, it will produce a magnetic field in a certain space it occupies, so all electrical conductors that can carry current have general inductance.

However, the inductance of the electrified long straight conductor is small and the magnetic field generated is not strong, so the actual reactor is the conductor of solenoid winding, which is called air-core reactor.

Sometimes, in order to make this solenoid have greater inductance, an iron core is inserted into the solenoid, which is called an iron core reactor. Reactance is divided into inductive reactance and capacitive reactance, and the more scientific classification is inductive reactance.
