Electric current measuring device in electric counter, includes primary conductor with flat U-shaped profile, and two branches presenting angles of torsion of 90 degrees in opposite directions

摘要

The device includes a primary conductor (2) having a circular core (16) centered on a central axis C, and first and second branches (19, 20). A secondary winding (6) is arranged between the first and second branches. The primary conductor (2) has flat U-shaped profile. First branch presents an angle of torsion of 90 degrees in one direction, and second branch presents an angle of torsion of 90 degrees in opposite direction.
