Abstract

An inductive sensor for measuring a current in a conductor includes a generally annular winding (10) delimiting a passage for the conductor. The winding extends homogeneously over most of the circumference of a ring except for a section (20) where the winding has a structural discontinuity. The sensor includes at least one identical complementary winding (12). The windings (10, 12) are disposed coaxially and oriented so that the structural discontinuities of the windings are regularly distributed in the angular direction about the common axis of the windings. The windings are connected in series.
