SUMMARY
The discussion centers on the adjustment of a 480 V, 200 kVAr capacitor bank originally designed for 60 Hz operation when relocated to a 390 V, 50 Hz environment. The capacitive reactance at 60 Hz is calculated using the formula X_{60} = P/V^2. To find the reactance at 50 Hz, the ratio of frequencies is applied: X_{50}/X_{60} = 60/50. This method allows for the determination of the new power rating of the capacitor bank at the altered voltage and frequency.
