Abstract
A transducer for measurement of a current includes a magnetic core, a single U-shaped flat conductor which has two wings, and a crown joining the wings. Each wing has two openings, and the magnetic core passes through the openings. The two wings constitute two conductive branches in thermal contact with one another, and each branch is adapted to carry a component of the current; the current component carried by one branch differs from the current component carried by the other branch. The current components give rise to opposite respective component fluxes in the magnetic core.
