A
transductor (not to be confused with a
transducer) is type of
magnetic amplifier used in power systems for compensating
reactive power. It consists of an
iron-cored
inductor with two windings - a main winding through which an alternating current flows from the power system, and a secondary control winding which carries a small direct current. By varying the direct current, the iron core of the transductor can be arranged to saturate at different levels and thus vary the amount of reactive power absorbed.
