Use of the current transductor in the aluminum industry
Theodore R. Specht, Robert N. Wagner · Electrical Engineering · 1950
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.
