How to determine the capacitance of a capacitor bank

Product Line
Power factor correction products

Resolution 

The capacitance of a capacitor bank can be calculated using the following formula:

For a 3 phase WYE connected capacitor bank :



For a 3 phase Delta connected capacitor bank :



For single phase:


Where C is capacitance in Farad, Q is reactive power in kVAR and f is Frequency in Hz.

For example. A three WYE phase capacitor bank stage is rated @100 KVAR, 480 Volts 60 HZ​ :
