Zusammenfassung:The Rogowski coil type sensor for measuring current includes a carrier and at least one secondary winding. The winding includes: at least one internal layer with a high turn density, which layer is wound in an "outward" first winding direction from the first end to a second opposite end of the winding, and at least one external layer with a low turn density, which layer is wound in a "return" second winding direction. The external layer with a low turn density includes: a first compensating portion with a high turn density, which portion is of small length and close to the first end, a central portion with a low turn density, which portion is of large length, and a second compensating portion with a high turn density, which portion is of small length and close to the second end.
