2. Electr. [See quot. 1939.] A reactor (sense 2 a) having a d.c. winding to control the saturation of a core and an a.c. winding whose impedance is thereby changed, so that a small change in direct current produces a large change in alternating current.
1939U. Lamm in ASEA Jrnl. XVI. 71/2 We should like to introduce some explanation of the word ‘transductor’... The purpose of this word is actually to express the idea that as regards the mutual action between its two windings the apparatus resembles a transformer whilst, however, at the same time functioning in the A.C. circuit as a reactor or inductor, i.e. a conductor. 1975IEEE Trans. Nuclear Sci. XXII. 1277/1 At Fermilab, transductors are used as current measuring devices in the main accelerator quadrupole power supply feedback loop. |
