Abstract
For optimizing the manufacturing cost of the magnetic torus of a differential transformer, the volume is reduced in that the free volume of the central aperture is fully filled: only one turn for each primary conductor, the section of which is reduced, the adjacent parts of larger section forming heat sinks, the central part of the conductors having the form of circular sectors. An important saving is secured on the most expensive part of the relay.
