Abstract

Transformer torus comprising a magnetic circuit consisting of a plurality of segments of sheet metal strip (2) permanently having the general shape of a slit cylinder, the various sheet metal segments (2) being arranged concentrically and being assembled in this position at at least one point (4) of their circumference, for example by welding. Application: in particular to measurement transformers, for example for detecting faults in electrical cables.
