Capacitive current + reactive power formula says:
•A 200uF (two hundred microfarads) capacitor at 230V (two hundred and thirty volts) AC 50Hz (fifty hertz) will pass a 14.45132620651A (fourteen point four five one three two six two zero six five one amps) capacitive current and the reactive power will be 3.323805027498kVAr (three point three two three eight zero five zero two seven four nine eight kilovolt amps reactive).•To compensate a 3.323805027498kVAr (three point three two three eight zero five zero two seven four nine eight kilovolt amps reactive) of inductive power at 230V (two hundred and thirty volts) AC 50Hz (fifty hertz) you need a 200uF (two hundred microfarads) capacitor, which will pass a 14.45132620651A (fourteen point four five one three two six two zero six five one amps) of capacitive current.
•For 14.45132620651A (fourteen point four five one three two six two zero six five one amps) of capacitive current at 230V (two hundred and thirty volts) AC 50Hz (fifty hertz), you need a 200uF (two hundred microfarads) capacitor. The capacitive reactive power of it will be 3.323805027498kVAr (three point three two three eight zero five zero two seven four nine eight kilovolt amps reactive).
