Above-ground regulator banks look like three garbage can-sized transformers held up by two utility poles. They regulate the voltage on the line to prevent undervoltage and overvoltage conditions. The regulator bank works to maintain a steady 7,200 volts running through the neighborhood on three wires (with a fourth ground wire lower on the pole).
Installing capacitors in electrical systems fulfils several functions. Although the most well-known is power factor compensation, they also improve the voltage regulation of transmission lines by reducing the voltage drop and increase the capacitive component of lines that are naturally inductive.

How do capacitor banks assist in voltage regulation? Capacitor banks play a vital role in voltage regulation by supplying reactive power when there is a demand, thereby stabilizing voltage levels within the electrical system. This is crucial for maintaining the reliability of power delivery and preventing voltage sags or surges.
Capacitor Bank Definition: A capacitor bank is a collection of multiple capacitors used to store electrical energy and enhance the functionality of electrical power systems. Power Factor Correction: Power factor correction involves adjusting the capacitor bank to optimize the use of electricity, thereby improving the efficiency and reducing costs.
Benefits of Using Capacitor Banks: Employing capacitor banks leads to improved power efficiency, reduced utility charges, and enhanced voltage regulation. Practical Applications: Capacitor banks are integral in applications requiring stable and efficient power supply, such as in industrial settings and electrical substations.
High voltage capacitor banks are composed of elementary capacitors, generally connected in several serial-parallel groups, providing the required electrical characteristics for the device.
Capacitive loads and inductive loads, such as electric motors, can significantly affect the power factor. By introducing capacitors in the form of capacitor banks, power factor correction can be achieved, ultimately enhancing the overall efficiency of the electrical system.
Composition of LV capacitor banks A distinction is made between fixed value capacitor banks and “step” (or automatic) capacitor banks which have an adjustment system that adapts the compensation to the variations in consumption of the installation.
This discharge may cause a rupture of the failed unit with possible damage to the rest of the bank. To prevent it, the maximum reactive power of one series section should not be higher than 4,650 kvar at a rated voltage and 60 Hz frequency. Refer to IEEE Std.
