Capacitor Banks Variation With Voltage and Frecuency

  1. May 1, 2010 #1
    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
    [tex] X_{60}=\frac{P}{V^2}[/tex]. Now its value at 50 Hz is found from
    [itex] \frac{X_{50}}{X_{60}}=\frac{60}{50}[/itex].
    From the value of [itex] X_{50}[/itex] and using new voltage 390 V you can find resulting power rating of your capacitor bank.
