Abstract
The present invention relates to a device 1 for measuring an electric current and is particularly well adapted to electricity counters. This device 1 comprises a primary conductor 2 having a general U-shape, said primary conductor comprising a core 16 substantially circular in shape centred on an axis C, said central axis, and two branches, said first 19 and second 20 branches and a secondary winding 6 sensitive to a magnetic field, said secondary winding being disposed between said first 19 and second 20 branch of said primary conductor 2. Said primary conductor 2 is a flat profile folded in a U, said first branch 19 exhibiting torsion 13 of an angle of 90° according to a first direction of torsion and said second branch 20 exhibiting torsion 12 according to an angle of 90° along a second direction of torsion.
Claims9
A device for measuring an electric current comprising:
- a primary conductor having a general U-shape, said primary conductor comprising a core of substantially circular shape centred on an axis (C) and two first and second branches;
- a secondary winding sensitive to a magnetic field, said secondary winding being placed between said first and second branch of said primary conductor, wherein said primary conductor is a flat profile folded in a U-shape, said first branch having torsion of an angle of 90° in a first direction of torsion and said second branch having torsion according to an angle of 90° in a second opposite direction of torsion so that said first branch and second branch are brought together locally so as to enclose said secondary winding as closely as possible.
