Reactors, like capacitors, are basic to and an integral part of both distribution and transmission power systems. Depending on their function, reactors are connected either in shunt or in series with the network. Reactors are connected either singularly (current-limiting reactors, shunt reactors) or in conjunction with other basic components such as power capacitors (shunt-capacitor-switching reactors, capacitor discharge reactors, filter reactors). Reactors are utilized to provide inductive reactance in power circuits for a wide variety of purposes, including fault-current limiting, inrush-current limiting (for capacitors and motors), harmonic filtering, VAR compensation, reduction of ripple currents, blocking of power-line carrier signals, neutral grounding, damping of switching transients, flicker reduction for arc-furnace applications, circuit detuning, load balancing, and power conditioning.Reactors can be installed at any industrial, distribution, or transmission voltage level and can be rated for any current duty from a few amperes to tens of thousands of amperes and fault-current levels of up to hundreds of thousands of amperes.
