The power factor correction of capacitor banks changes due to moisture, temperature, time, and harmonics. To perform their best, the installed capacitor banks must be tested regularly and maintained to the highest quality. Although capacitor banks of the finest qualities function quite well, their operation can weaken with time.
These drives are still the most common large power type of motor speed control for applications requiring very fine control over wide speed ranges with high torques. Power factor correction is particularly important for this drives because of relatively poor power factor, especially when the motor is at reduced speeds. Additional trans‐

When a power supply creates a potential difference between the plates, the capacitor stores charge until its voltage matches the supply voltage.

A capacitor bank in a substation is a grouping of capacitors connected together to enhance the power quality by providing reactive power support. It works by storing electrical energy and releasing it when needed, thus helping to regulate voltage levels and improve overall system efficiency.
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.
Overall, capacitor banks are protected by a combination of fuses, which remove the failed unit or element, and protective relays, which alarm and trip the bank offline.
In this case the power of capacitors is fixed to supply the constant reactive power to the exiting load. Even the load should not be changed. When the loads that need to be compensated are variable (this currently happens in most cases), we suggest an automatic power factor correction. The total power of the capacitor bank is divided in steps.
