The purpose of a reactor varies in industrial circles but the determination of saturation for various input frequencies has not been standardized when the reactor is used. The present invention allows a user to detect a current flowing through the reactor to formally determine the saturation of the reactor, compare the size of harmonic components included in the current with current basic wave components through Fourier transform, and determine the saturation of the reactor.
