Inrush current calculation for Capacitor bank

[22574]

Does anyone have a formula in calculating the inrush current for Capacitor Bank.

The scenario is: there are two Capacitor Banks connected in parrallel, in each bank there is a series damping reactor connected.

Thanks.

Yes, the following two sources will give you simple formulas you can use to calculate the inductance and current you will see based on a selected inrush current:
