Abstract

Toroidal fluxgate current transducer comprising a ring shaped fluxgate sensing unit (6) comprising a ring-shaped support (40), a saturable magnetic core (38) mounted on the support (40), an excitation coil (44) wound around the support and saturable core and a magnetic shell (32) mounted around the excitation coil, ring-shaped support and saturable core. The support is ringed-shape and comprises terminals (50,48) fixed to the support, a first pair of said terminals connected to ends of the excitation coil, and a second pair of said terminals connected to ends of a secondary coil of the current transducer.
