Use of the current transductor in the aluminum industry

THE CURRENT transductor is one of the great family of apparatus known variously as magnetic amplifiers, saturable core reactors, or transductors. These devices are a-c inductors, whose effective inductance can be changed by superimposing a d-c magnetomotive force. The current transductor is a transductor specially designed and calibrated so that the alternating current flowing in the a-c circuit is a direct measure of the direct current which is flowing in the d-c circuit. The transductor is meant to be used for the measurement of the direct current.
