Toroidal fluxgate current transducer

Toroidal fluxgate current transducer comprising a ring shaped fluxgate sensing unit comprising a secondary coil made of a conducting wire, a ring-shaped dielectric support, a saturable magnetic core mounted on the support, an excitation coil made of a conducting wire wound around the support and saturable core, and a magnetic shell mounted around the excitation coil, ring-shaped support and saturable core, wherein the support comprises terminals 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 the secondary coil of the current transducer.

Toroidal current transducer comprising a housing, a ring shaped magnetic field sensing unit mounted in the housing, and a central passage, wherein the transducer comprises a primary conductor unit provided as a separate component, comprising a dielectric body and one or more conductors configured for carrying a current to be measured held together within the dielectric body forming a general U or V-shaped component separably mountable through the central passage of the housing and lockable to the housing by complementary locking members provided on the dielectric body and housing.
