Capacitor banks provide reactive power compensation by introducing capacitive reactive power into the system, which is especially useful for counteracting the inductive reactive power typically drawn by motors and transformers. Capacitors store electrical energy in the electric field created between their plates when a voltage is applied.
For example, the configuration for a 5-stage capacitor bank with a 170 KVAR maximum reactive power rating could be 1:1:1:1:1, meaning 5*34 KVAR or 1:2:2:4:8 with 1 as 10 KVAR. The stepping of stages and their number is set according to how much reactive power changes in a system.
Power capacitors are rated by the amount of reactive power they can generate. The rating used for the power of capacitors is KVAR. Since the SI unit for a capacitor is farad, an equation is used to convert from the capacitance in farad to equivalent reactive power in KVAR.
