EN 61921:2005 describes the general requirements for the capacitor bank. The most important of them are listed below: Index of protection depends of the place of the installation of a capacitor bank. If the capacitor bank is to be placed in the same place as the main switchgear or utility room next to it, IP 20 is enough.
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.
As an example, if it was found, that in the grid there are following harmonics: 5 th, 7 th, 11 th, 13 th the LC parameters has to be selected so that the resonance frequency is included in range 174 – 210Hz (usually 189Hz). This type of filtering is being used in the automatic capacitor banks.
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.
The short circuit protection of the capacitors is provided by the switch disconnectors. For the capacitors the fuse link rated current should be 1.6 time of the rated reactive current of the capacitor. In=Q / (Un×√3) where: Q – rated power of the capacitor at rated mains voltage.
Q – rated power of the capacitor at rated mains voltage. Not only capacitors should be protected against short circuit, but the whole capacitor bank as well. Usually, in the switchgear from which the CB is supplied, there is an additional circuit breaker for the capacitor bank. Its value should be selected as:

A variable air capacitor (Figure (PageIndex{7})) has two sets of parallel plates. One set of plates is fixed (indicated as "stator"), and the other set of plates is attached to a shaft that can be rotated (indicated as "rotor"). By turning the shaft, the cross-sectional area in the overlap of the plates can be changed; therefore, the capacitance of this system can be tuned …
