Answer Posted / nagesh.patwari
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.
Capacitors shall be connected near to the load.Some times Capacitor Banks are connected with the Motor Control Center (MCC) or Power Control Center (PCC) for improving the P F of the system. The voltage rating shall be 10% higher than the system voltage.
