Abstract

PURPOSE:To prevent adverse influence due to the deflected magnetization of a transformer and a reactor by detecting a DC deviation flowing in the transformer or the reactor through the use of a Hall element and generating a magnetic field in the direction of compensating the DC deflected magnetization with respect to the transformer or the iron core of the reactor. CONSTITUTION:The output Hall voltage Ey of the Hall element 1 which has been integrated in the transformer is amplified in an adequate size by an amplifier 6 and it turns into a voltage Eyad. The voltage Eyad pass through a high pass filter 7, turns into a voltage Eya for an alternating current and they are inputted to a differential amplifier 11. The voltage Eya in which the alternating current and a direct current is inputted to the differential amplifier 11 without passing through the high pass filter 7. The differential amplifier 11 takes a difference (Eyad-Eya) between the voltage Eya for the alternating current and the voltage Eyad including the alternating current and the direct current, makes out an direct current Iyd corresponding to the difference, and sets the direct current Iyd to flow into an deflected magnetization compensating winding which makes a magnetic field for compensating the deflected magnetization. Thus, the magnetic field in an inverted direction, which compensates the deflected magnetization optimum in size and direction always can be made.
