A shunt capacitor bank (or simply capacitor bank) is a set of capacitor units, arranged in parallel/series association within a steel enclosure. Usually fuses are used to protect capacitor units and they may be located inside the capacitor unit, on each element, or outside the unit. Capacitor banks may be star or delta connected.
A capacitor bank is an assembly of multiple capacitors and is designed to manage and store electrical energy efficiently. The multiple capacitors in a capacitor bank have identical characteristics and are interconnected in either series or parallel arrangements to meet specific voltage and current requirements. This modular setup facilitates the storage of energy and
Capacitor banks and harmonic filter banks in the 2.4kV through 34.5kV voltage range can be equipped with zero voltage closing controls to nearly eliminate switching transients.
It can be obtained by mounting the transformer with the ratio 400/230. Go back to contents ↑ . 5. Protection. 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. I n =Q / (U n ×√3) where: U n – rated voltage of the mains, Q

Capacitor banks act as a source of local reactive power and thus less reactive power flow through the line. By using a capacitor bank, the power factor can be maintained near to unity. Improving power factor is the process of reducing the phase difference between voltage and current.

This reactive power is provided by the capacitor bank installed parallel to the load. Capacitor banks act as a source of local reactive power and thus less reactive power flow through the line. By using a capacitor bank, the power factor can be maintained near to unity.
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.
Improving power factor is the process of reducing the phase difference between voltage and current. Basically capacitor banks reduce the phase difference between the voltage and current. On the addition of power bank, the current leads the voltage, hence the power factor angle is reduced.
Capacitor banks play a pivotal role in substations, serving the dual purpose of enhancing the power factor of the system and mitigating harmonics, which ultimately yields a cascade of advantages. Primarily, by improving the power factor, capacitor banks contribute to a host of operational efficiencies.
The common practice is to detune the capacitor bank so that the lowest order load current harmonic sees a very small impedance. This is achieved by adding an inductor in series with the power factor correction capacitors leading to a situation commonly known as series resonance.
