A current sensor (10) based on a Rogowski coil that comprises a polygonal cross-section tube obtained from one or more parts of rigid PCB, wherein the windings that form the Rogowski coil are located on the portions of rigid PCB which form the flat faces of the polygonal cross-section tube and wherein the one or more parts of rigid PCB are joined together by means of flexible zones which can bend in a hinge-like manner to form the tube, the polygonal cross-section tube being designed so that, during its use, the conductor (11) whose current is required to be measured is situated along the tube's longitudinal axis. |
