摘要： A current sensor for an electrical device including a primary circuit in which a primary current flows. A magnetic circuit includes two identical U-shaped elements between which two studs for air gaps are located. A secondary circuit includes two similar coils of a cylindrical shape, mounted in series and encircling the air gaps, wherein these two coils are made in a continuous way with only one winding operation without any electrical connection between both coils. The winding of the primary circuit encircles one of the two coils. The sensor is designed so that it may be adapted to several nominal ranges of primary current by varying the number of passages of the primary circuit between coils, the number of windings of the secondary circuit, and the thickness of the air gaps.
