Inductive current + reactive power formula says:

•A 100mH (one hundred millihenrys) inductor at 230V (two hundred and thirty volts) AC 50Hz (fifty hertz) will pass a 7.321127382227A (seven point three two one one two seven three eight two two two seven amps) inductive current and the reactive power will be 1.683859297912kVAr (one point six eight three eight five nine two nine seven nine one two kilovolt amps reactive).
•To compensate a 1.683859297912kVAr (one point six eight three eight five nine two nine seven nine one two kilovolt amps reactive) of capacitive power at 230V (two hundred and thirty volts) AC 50Hz (fifty hertz) you need a 100mH (one hundred millihenrys) inductor, which will pass a 7.321127382227A (seven point three two one one two seven three eight two two two seven amps) of inductive current.
•For 7.321127382227A (seven point three two one one two seven three eight two two two seven amps) of inductive current at 230V (two hundred and thirty volts) AC 50Hz (fifty hertz), you need a 100mH (one hundred millihenrys) inductor. The inductive reactive power of it will be 1.683859297912kVAr (one point six eight three eight five nine two nine seven nine one two kilovolt amps reactive).
