Abstract

A current transducer (1) comprises a primary conductor bar (2), a magnetic field sensor (4), and a magnetic circuit core (14) comprising a U-shaped first core part (14a) and a U-shaped second core part (14b), each magnetic core part comprising an upper branch (15a) and a lower branch (15b) connected together by an end branch (15c). The primary conductor bar comprising a sensor orifice (5) extending through the primary conductor bar, the magnetic field sensor positioned in and extending through the sensor orifice, the magnetic field sensor having first and second spaced apart sensing elements (6a, 6b) with a measurement sensitivity direction (S) transverse to the general current flow direction (A). The first sensing element (6a) is positioned within the first airgap and the second sensing element (6b) is positioned within the second airgap.
