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.
It is common practice to leave the star-connected capacitor banks ungrounded (there are separate reason for leaving it ungrounded) when used in the system or use delta-connected banks to prevent the flow of third harmonic currents into the power system through the grounded neutral.
When designing a capacitor bank, many factors must be taken into consideration: rated voltage, kvar needs, system protection and communications, footprint and more. These factors govern the selection of the capacitor units to be used, along with proper grouping of these units.
When capacitor units in a capacitor bank fail, the amount of increase in voltage across the remaining units depends on the connection of the bank, the number of series groups of capacitors per phase, the number of units in each series group, and the number of units removed from one series group.
Bank stability for a fuseless capacitor bank is similar to that of an externally fused capacitor bank and defined by shorted series sections, internal to individual capacitors. The voltage on the remaining series sections in the string should not exceed 110% of its rated voltage.
We have seen that a capacitor bank is used for the improvement of power factor and reactive power compensation in a substation. As the role of this bank is very important, it becomes critical to see that the bank is maintained well. Also, it has to be seen which parameters of this bank should be specified for installing it into the substation.

What Does a Capacitor Bank Do. A capacitor bank is used to store electrical energy and improve the performance of electrical systems by providing reactive power support. Its main functions are: Power Factor Correction: In power systems, electrical loads often consume both real power (used to do work) and reactive power (needed to maintain voltage levels).

In power electric systems capacitors and capacitors banks, which must be in accordance with IEC[1] Standards 60143 and 60871 or IEEE[2] Standard 824, are used to: Compensate reactive energy (power factor correction) due to consumers (MV and LV) and the inductive effect of long overhead lines and underground cables (MV and MV).
Relaying for capacitor-bank protection includes overcurrent (for fault protection), overvoltage, system problem detection, and current or voltage unbalance, depending on bank configuration, for monitoring the condition of the capacitor units.
Capacitor banks provide an economical and reliable method to reduce losses, improve system voltage and overall power quality. This paper discusses design considerations and system implications for Eaton''s Cooper PowerTM series externally fused, internally fused or fuseless capacitor banks.
They manage the operation of the capacitor bank, ensuring it responds correctly to network conditions and is protected from faults or other potentially damaging events. Together, these components form a capacitor bank capable of providing vital reactive power support and other benefits to the electrical grid, helping to maintain voltage stability and improve overall system …
