Customer ServiceDetuned reactors are three-phase inductors that play a crucial role in attenuating the amplification of harmonics in networks rich in harmonics. They are also used in series with capacitor banks to prevent harmonic amplification caused by resonance.
Customer ServiceShould just make different tiers of capacitors. Much easier solution and provides more depth to the building. Do you put a reactor for quick energy or a capacitor for buffered energy? With them being essentially s reactors they''re kind of useless in their intended design imo once you get comfortable with m reactors. Or running hungry enough
Customer ServiceTo avoid this problem, it is common to insert reactors in series with capacitor banks. The reactor also by its nature will safeguard capacitor and associated switch gears against switching inrush, which other may damage capacitors, circuit breakers and contactors. Why use Detuned reactor?

Customer ServiceReactors may be used as line or load reactors (see Figure 1). Line reactors are used when low line impedance allows high inrush current, when power factor correction
Customer Service35% when a properly sized reactor is used. This effect is also beneficial to the DC filter capacitors. Since the "ripple current" is reduced. The capacitors can be smaller, run cooler and last longer. Though harmonic mitigation is an important reason to use a line reactor, most drives at the 10 horsepower rating
Customer ServiceCapacitor-Bank Reactors: These reactors are used in combination with capacitor banks for power factor correction. They help control the flow of reactive power and maintain a desired power factor in the system. Thyristor-Controlled Reactors (TCRs): TCRs are used to dynamically adjust the amount of reactive power injected into the system. They
Customer ServiceTo prevent damage from high inrush current, a reactor is connected in series with each capacitor in the bank. The reactor opposes any sudden change in current and limits the inrush current when the capacitor is switched on. The reactor also helps to limit the harmonic distortion caused by the switching of the capacitor bank.
Customer ServiceThe use of a reactor in a capacitor bank serves to prevent harmonic resonance. Capacitor banks can interact with the inductive elements of the power system, potentially causing resonant conditions that amplify harmonic currents.
Customer ServiceReactors may be used as line or load reactors (see Figure 1). Line reactors are used when low line impedance allows high inrush current, when power factor correction capacitors are used, or when a motor drive causes notching. Load reactors are installed at the output of a motor drive.
Customer ServiceWhy do we use capacitors when batteries can very well store charges? There''s an important point that, so far, I don''t see in other answers. Neither of these devices store charge! A "discharged" battery or capacitor contain the same net quantity of electrical charge as a "fully charged" battery or capacitor. What they are "charged" with is energy, not electrical charges.

Customer ServiceElectrical reactors are typically used on a transmission line when it''s necessary to limit currents that could damage a power transformer or other power system. This type of current-limiting reactor often relies on inductive reactance. The additional inductance and reactance are then added to the series which is key to the function of an electrical reactor or series reactor.

Each type serves different purposes based on the specific needs of the system. Fixed Capacitor Banks: Used in systems with consistent reactive power demand.
Customer ServiceA lot have mentioned that we use capacitors to correct power factor because loads are inductive, like motors. I''d like to expand a bit on the relationship between the two because your question shows good understanding of the basics but you''re missing a few key points which will make the whole thing come together.
Customer ServiceHaving discusses about capacitor bank, the major reason why reactor is used in them is because it reduces the current transient at the instant of switching on the capacitance.

One of the unwanted effects is the overheating of capacitor banks that are needed to maintain the power factor within the parameters required by the power authority, with a resulting, significant reduction in the average working life. The ideal solution is to insert block reactors in series with capacitor banks.
Hence, the use of detuned reactors in series with capacitors offers higher impedance for harmonics, thus eliminating the risk of overload in capacitors. The inductance value of detuned reactors is selected such that the resonance frequency is less than 90% of the dominant harmonic in the spectrum.

Capacitors are capacitive loads, mainly used to compensate reactive power and store energy.
Shunt reactors are connected in parallel with capacitors to limit the overvoltage that can occur due to the resonance between the reactive power sources. They help maintain the stability of the system.
Inductive reactors can help to raise the voltage by introducing a voltage drop in the circuit, which can be useful in cases where the voltage is too high. Conversely, capacitive reactors can lower the voltage by absorbing reactive power and reducing the voltage levels.
