Rogovski coil

Abstract

The Rogovski coil (1) is provided with a winding (2) applied to a winding support made from an insulating material. It has a central axis (4) and an opening (5), which is enclosed by the winding support and is penetrated by the central axis (4). A particularly homogeneous winding (2) and, associated therewith, very accurate current measurement are achieved by virtue of the fact that a surface, facing the central axis (4), of the winding support is provided with first stops (7), which are distributed on the circumference, extend in the direction of the central axis (4), and divide the winding (2) into winding segments (9). In this case, the spacing between in each case two of the first stops (7) is always an integral multiple of the diameter (D) of the wire forming the winding (2).
