6 FAQs about [Matching of reactors and capacitors]

Why are detuned reactors used in series with capacitors?

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.

How to put Series reactors with PF improvement capacitors?

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.

How do you calculate reactor capacity X reactance rate?

Reactance ratio refers to the ratio of reactance value of series reactor to capacitance reactance value of capacitor bank.

What is a series combination of inductive reactors and capacitors?

To overcome all the specified problematic issues, one simplest method is normally used. That is to use the series combination of Inductive reactors and Capacitors, instead of plain capacitors. Such series Inductive Reactors are known as “Detuned Reactors” or “Anti-Resonant Reactors” or “Detuned Anti-Resonant Reactors”.

How can a detuned reactor avoid resonance?

This resonance can be avoided by putting a detuned reactor in series with the capacitor. The reactor shall be such that the tuning frequency with the capacitor shall be less than the dominant harmonics. This combination of power factor correction capacitor and detuned reactors behaves inductively to frequencies above the tuning frequency.
