A Rogowski coil includes: a multilayer printed circuit board having a plurality of layers forming at least an outer top circuit board surface, an outer bottom circuit board surface, an inner top circuit board surface, and an inner bottom circuit board surface; a first winding formed by a plurality of tracks arranged alternately on the outer top circuit board surface and the outer bottom circuit board surface, the plurality of tracks being electrically connected by vias extending from the outer top circuit board surface to the outer bottom circuit board surface; and a second, return winding enveloped by the first winding. The multilayer printed circuit board includes a central passage opening for passage of a current conducting conductor. Axes of the first and second winding are arranged concentric around the central passage opening. The first and second winding are electrically arranged in series.

Rogowski coil

A sensor for measuring current in a conductor has a substrate in the form of a stratified plate having a first metallization layer, a second metallization layer and an isolation layer between the first metallization layer and the second metallization layer, the substrate having a coil that winds along a coil axis parallel to the first metallization layer, having at least one winding. Each winding has a first track in the first metallization layer connected by a via through the first isolation layer to a second track in the second metallization layer, and the substrate has a measurer to measure the current in the coil, and having at least one winding only winding around non-magnetic material.
