When a number of capacitors are connected together it forms a capacitor bank. They can be connected in series or parallel. A capacitor bank has numerous advantages and applications. Most of the time, these are used for reactive power compensation and power factor improvement. The arrangement of these can be done at substation or power plants.
The size and rating of capacitor banks are determined by the specific needs of the electrical system, such as the amount of reactive power needed or the desired level of voltage support. Capacitors in a bank can be arranged in parallel to increase total capacitance or in series to manage higher voltages.
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.
It helps you to shape up your technical skills in your everyday life as an electrical engineer. The purpose of a capacitor bank’s protective control is to remove the bank from service before any units or any of the elements that make up a capacitor unit are exposed to more than 110% of their voltage rating.
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.
Types of Capacitor Bank Definition: Capacitor banks are defined as groups of capacitors connected together to improve the power factor in electrical systems, available in three main types: externally fused, internally fused, and fuse-less.

Automatic capacitor bank. An automatic capacitor bank is a device that, after detecting the presence of inductive reactive energy above the desired value in an electrical installation, acts by automatically connecting capacitor groups (steps) necessary to adapt to the demand and keeps the PF roughly constant (IEC 61921, 2017).

Choosing a Voltage Rating for the Capacitor Bank In no case should the voltage rating be lower than the maximum expected usual operating voltage. A higher rating could be considered to promote capacitor bank availability vis-a-vis, lowering the expected failure rate of capacitor units. A higher voltage rating also provides for margin during ...
