Reactor
A Reactor is an essential electrical device used in power systems to control current, manage voltage, filter harmonics, and protect equipment. By providing inductive reactance, a Reactor can limit fault currents, reduce voltage fluctuations, and improve overall power quality. The Reactor is widely applied in industrial, commercial, and utility power networks to enhance system stability and reliability.
Working Principle of Reactor
The Reactor works by creating inductive reactance in an electrical circuit. When alternating current (AC) flows through the Reactor, it opposes changes in current and stores energy in its magnetic field. This property allows the Reactor to control current, limit inrush currents, reduce harmonics, and stabilize voltages in both transmission and distribution networks. Different types of Reactors are designed for series or parallel connections depending on the application.
