Why reactors are used in power system and their types

Why reactors are used in power system and their types

Reactors are used to limit the short circuit currents which can cause damage to the equipments of the power system. The additional reactance added in series with the system for protection, are called reactors. A current limiting reactor is a type of reactor which limits the heavy flow of current through other sections of the system.
