Capacitive Reactance
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.
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).

What is a Capacitor Bank?
Capacitors are electrical and electronic components that store electrical energy. Thus, capacitor banks (cap bank) stores the reactive energy (leading) and it compensate for reactive energy (lagging), and improves the power factor. As a result, the grid gets more stable and higher transmission capacity and suffers fewer transmission losses.
Shunt Capacitor : Rating, Connection, Advantages & Its
The advantages of shunt capacitor include the following. When the reactive power is decreased then the loss of transmission power can be decreased by reducing reactive current; The power factor for the source of the generator can be increased; High capacity is accessible to supply the power toward the load.
