How to configure the reactor capacitor

Does a capacitor bank need a reactor?

Table 3– Detuning factor and corresponding resonance frequency Since the detuning factor for the project was given as p=7%, one knows that the capacitor bank needs to be equipped with reactors.

How is voltage determined in a reactor and capacitor?

e reactor and capacitor. It is determined with a fundamental frequency of the distribution network of the reactor whichlinspecifies the maximum current, up to which inductance does not d 1,38CAPACITOR VOLTAGEA series connection of reactor and capacitor causes an increase of voltage at

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 series of capacitors for PF correction?

Considering power capacitor with rated power of 20 kvar and rated voltage of 440V supplied by mains at Un=400V. This type of calculation is true, if there is no reactor connected in series with capacitor. Once we know the total reactive power of the capacitors, we can choose series of capacitors for PF correction.

What is the detuning factor of a capacitor bank?

Since the detuning factor for the project was given as p=7%, one knows that the capacitor bank needs to be equipped with reactors. For this reason, some calculations have to be performed, in order to fit the power of the capacitors and its rated voltage taking into account reactive power of a detuning reactors.

How do you calculate a power rating for a capacitor bank?

For each step power rating (physical or electrical) to be provided in the capacitor bank, calculate the resonance harmonic orders: where S is the short-circuit power at the capacitor bank connection point, and Q is the power rating for the step concerned.
