Configuration of Capacitor bank. A delta-connected bank of capacitors is usually applied to voltage classes of 2400 volts or less. In a three-phase system, to supply the same reactive power, the star connection requires a capacitor with a capacitance three times higher than the delta connected capacitor. In addition, the capacitor with the star …
