Why do block reactors need capacitor banks?
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.
What is a detuned reactor and capacitor Assembly?
The detuned reactor and capacitor assembly is capacitive for frequencies below fr, so allows reactive energy compensation. The detuned reactor and capacitor assembly is inductive, so prevents amplification of the harmonics. The serial frequency (fr) chosen must be below the first harmonic order present in the circuit.
How to put Series reactors with PF improvement capacitors?
The easiest method that can be seen is to put the reactors in series path with the PF improvement capacitors. Still one has to understand that putting series reactors with Capacitors has to be done with utmost care. There are various issues with regards to right value selection, right rating and right reliability aspect selection.
What is the function of a capacitor?
The capacitor has the function of "connecting AC and isolating DC", that is, in the AC circuit, the frequency characteristic of capacitive reactance is used to "connect high-frequency AC and block low-frequency DC". Capacitors are capacitive loads, mainly used to compensate reactive power and store energy.
What types of reactors are used in a power system?

Reactors in a Power System
Reactors 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. Load reactors help eliminate voltage spikes or reflected ...

Why is the Reactor Connected with a Capacitor in a Series?
As a matter of fact, the function of the reactor is large. The reactor is also named as the inductor. The reactor is mainly used to limit the short-circuit current. Moreover, it can also be connected with the power capacitor in series or parallel in the filter to limit the higher harmonics in the power grid.
Reactors in a Power System
Capacitor banks are often used to correct low-power-factor situations. In systems with large amounts of capacitance used to correct power factor, high-voltage distortion can cause resonance at system harmonic frequencies. This results in series-or parallel-resonant currents, which can be very damaging to the electrical system.

What is the reason for using reactor in capacitor bank?
To 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.
