What is a capacitor bank?
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.
Why are capacitors connected in series?
When a number of capacitors are connected together in series or parallel, forms a capacitor bank. These are used for reactive power compensation. Connecting the capacitor bank to the grid improves reactive power and hence the power factor. As shown in the figure, capacitors are connected in series to improve the power factor rating.
Do capacitor banks improve power quality?
