How to select a capacitor bank for power factor correction?
The total power of the capacitor bank is divided in steps. These steps are controlled by a regulator which constantly analyses the network and operates the step with suitable power, in order to compensate the load present at that moment. Here is a formula that can help you choose: (Q(c) / S(n)) * 100 = %
