<p>The sensor has a magnetic circuit (10) including an elongated ferromagnetic core (11) with parts (11a, 11b) situated at ends of a large axis of the core and provided with a flux compensating winding of small thickness. The winding compensates flux generated by current to be measured. An annular enclosing case (1) has a cylindrical inner wall (3) provided with diametrically opposed recesses extending in the direction of a cylindrical outer wall (2) to the ends. A fixing and support frame surrounds the outer wall of the case.</p> |
