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).

If only the number of steps is specified, for example (3), one manufacturer may propose a (3) stage bank with 1:1:1 switching, the other may propose a less expensive (2) stage bank with 1:2 switching.

An electric field forms across the capacitor. Over time, the positive plate (plate I) accumulates a positive charge from the battery, and the negative plate (plate II) accumulates a negative charge. Eventually, the capacitor holds the maximum charge it can, based on its capacitance and the applied voltage.

Depending on the size of a compensation unit, it is assembled with capacitors of equal size (in bigger units) or of different size. A unit with a total reactive power of, for example, 300 kvar consists of six power capacitors, of 50 kvar each. Thus the number of capacitors is identical to the number of steps: six capacitors controlled by six steps.
