Abstract
The object of the invention is to provide a slotted current acquisition coil according to the Rogowski principle in which the printed circuit board base of the measuring coil can be opened to insert an electrical conductor to be measured without having to interrupt the latter. To this end, the two printed circuit board segments linked together by a hinge are opened. Twisting a single-piece printed circuit board also opens the arrangement for inserting the conductor to be measured.
