Zusammenfassung:	The toroid (2) has a band made of magnetic material, provided with a constant sensible section and winded in a manner to form a succession of turns. The band has two triangular end parts (18) extended on a predetermined length from ends (8) of the band. Each end part is equipped with a magnetic flow homogenization unit that is formed by a non magnetic shim, a reduction element and a recess for homogenizing magnetic flux to gradually reduce magnetic coupling between the end part and a turn (6-2) towards the ends of the band. An independent claim is also included for a switchgear comprising primary conductors.
