Abstract
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.
