# Capacitor Banks Variation With Voltage and Frecuency

Hi,

I have a 480 V, 200 kVAr and 60 Hz capacitor bank. I need to move this bank to a location with 390 V and 50 Hz, I wonder what would be the resulting power of the bank.

Regards.

Find value of capacitive reactance at 60 Hz
$$X_{60}=\frac{P}{V^2}$$. Now its value at 50 Hz is found from
$\frac{X_{50}}{X_{60}}=\frac{60}{50}$.
From the value of $X_{50}$ and using new voltage 390 V you can find resulting power rating of your capacitor bank.
