Capacitor banks are also known by various names such as power factor correction capacitors, reactive power compensation capacitors, or simply, power factor correction units. A typical power factor correction capacitor bank cabinet consists of capacitors connected in parallel with the load, controlled by an automatic capacitor control unit through a contactor.

The capacitors' life span is calculated by extrapolating the results of an ageing test. The IEC 61049 standard serves as the reference. The following calculation method is used: The ageing test involves submitting the capacitor to a test voltage greater than the rated voltage for a given period of time at the maximum operating temperature.
The IEC 60831 standard stipulates that the capacitors must be capable of operating for 1,500 hours with a voltage 25% higher than the rated voltage, without any short-circuits occurring and with a capacitance loss under 5%. For example, for a 400 V capacitor, the test is carried out with a voltage of 500 V.
We use capacitors to supply the reactive power to the inductive receivers and to raise the displacement power factor (Cos ϕ). Summary When an energy supplier supplies reactive power, it overloads the lines and transformers.

Four "types of capacitors" are proposed, depending on the level of harmonic pollution (Sh/ Sn) : Standard type: voltage 400 V H type: reinforced voltage 440 V or 500 V SAH type: reinforced voltage + anti-harmonic inductive circuit FH type: harmonic filter. Survey of the installation by the Audit & Troubleshooting Department.
For example, for a 400 V capacitor, the test is carried out with a voltage of 500 V. With a 5% capacitance loss, it can be deduced that the estimated life span is 10 years.
