The effects of reactors and capacitors connected to power systems
Nonlinear elements connected to power systems cause harmonic currents in them. Even though the source voltage of nonlinear elements is sinusoidal, their currents are nonsinusoidal. Nonsinusoidal currents include harmonic components which can be obtained by Fourier analysis. Nonlinear elements such as converters, gas discharge, lighting, arc furnaces, and VAr

6 FAQs about [Capacitor dedicated reactor table]
What is a detuned reactor in a capacitor bank?
Detuned Reactors in Capacitor Banks: Mitigating Harmonics and Preventing Resonance Introduction Harmonics in Power Systems Resonance in Power Systems Capacitor banks, a common feature in power systems, are employed to optimize power factor and enhance overall system ef・iency.
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.
Why do reactors need a capacitor?
High demands are placed on reactors. Reactors are connected in series with capacitors and thus need to be able to withstand losses resulting from both fundamental and other harmonic currents without the temperature range of the insulation material being exceeded under actual environmental conditions.
Does a detuned reactor need a capacitor duty contactor?
When you are using a detuned reactor you need not to use a capacitor duty contactor ( contactor with Damping Resistor). You can use a normal power contactor. Detuned reactors impedance limits the inrush current during switching hence capacitor duty contactor is not required. Capacitor duty contactor is needed for the switching of capacitors only.
How to calculate capacitance of 3 phase capacitor with detuned reactor?
It will be calculated from the following equation: For 3 phase capacitor with detuned reactor , the capacitance equal 3 x 332 μF at 400 V /50 Hz with blocking factor p = 7%. Calculate the capacitor KVAR. We should choose a capacitor with nominal voltage Un higher than Uc.
How to choose the rated voltage of capacitors in a detuned power factor correction system?
The rated voltage of the capacitors must be chosen according to the resonance frequency. In detuned power factor correction systems, presence of higher voltage rated capacitors and reactors causes a difference between rated capacitor power and obtained reactive power.
