Detuned Reactor Capacitor Bank

Automatic capacitor banks with detuned filters r 5 6 r5 6 3 automatic capacitor banks with detuned filters r 5 6 the fr fre capacitor banks with de tuned filters have been designed for power compensation purposes in net works with a high content of harmonics and where there is a risk of resonance.

Detuned reactor capacitor bank.

Ripple control coupling capacitors surge capacitors medium voltage commutating capacitors energy storage impuls capacitors capacitor banks capacitor banks standard capacitor banks detuned 7 capacitor banks detuned 7 fast switched high voltage capacitor banks components for pfc pfc controllers contactors for capacitors reactors. Capacitor is widely used in industry to improve power factor. Having understand what reactor is and the various types available it is crucial to know why the series type is used in capacitor bank. 2 x phmkp 440 3 28 1 note 1 for filter circuits the capacitor rated voltage has always to be chosen higher than the supply voltage.

Normally detuned reactors are made in 5 67 7 and 14 for which detuning frequency is 210 189 and 134hz respectively. Nowadays installations with a high con. The time delay must be adapted to capacitor discharge time. Also this series lc.

Power factor capacitors and detuned filters. Formula 1 calculation of capacitor impedance if we look to the impedance equation of the capacitor it is seen that the capacitor impedance decreases with the increase of the frequency. By using these types of detuned reactors it is possible to avoid fol lowing negative effects on system overcurrent during switching on the capacitor banks overload of capacitor banks because of the harmonic resonance. 50 kvar x 1 125 56 25 kvar selection.

But capacitors need a series reactor to limit the starting inrush current. Required rated output of the capacitors. Fundamental voltage increased by the reactor and harmonics supply voltage 400 v rated voltage 1 of capacitor v. Number and power of steps sequence etc.

For a multi step banks in close proximity to each other series reactors will be part of each separate bank for the purpose of limiting inrush current during back to back switching. Detuned reactor detuned reactors or harmonic filter reactors are used in power factor correction panels in series with capacitors to avoid resonance due to presence of harmonic currents of various frequencies. 7 tests to be done after production of the bank at the end of the manufacturing process.
