Is a reactor an inductor?
Reactors: A Reactor is a ferromagnetic core Inductor type, the purpose of which is to introduce inductive reactance into a high current AC power line or load circuit in order to increase its impedance. In electrical transmission systems reactors are used to limit switching and fault currents.
What does a reactor do in an electrical circuit?
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.
What is the main purpose of an inductor?
An inductor has the functions of developing electromotive force in the direction that reduces fluctuation when a fluctuating current flows and storing electric energy as magnetic energy.
What does an inductor do in a filter?
An inductor placed in series (in line) with a conductor, such as a wire or circuit board trace, blocks or impedes changes in current and functions as a low pass filter. Because inductors restrict or choke changes in current, they are also called “chokes”.
Is a coil an inductor?
An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An inductor typically consists of an insulated wire wound into a coil.
What happens when DC supply is given to inductor?
When an Inductor is connected to a circuit with Direct Current (DC) source, two processes, which are called “storing” and “decaying” energy, will happen in specific conditions. The sudden increase of current in the Inductor produces an Self Induced Electromotive Force, vemf, opposing the Current change, Figure 1.
How is energy stored in an inductor?
Inductor stores the kinetic energy of moving electrons in the form of a magnetic field. Energy storage in an inductor is a function of the amount of current through it. The more the current , the more the magnetic field and the more energy is stored.
