| description | The invention relates to a device (10) for recovering energy from a single-phase power cable (1), the single-phase power cable (1) comprising two phase conductors (C1, C2). The invention relates to a power cable (1) comprising a magnetic core (20) in the form of a split toroidal surface mounted around the power cable (1) so as to form a magnetic circuit capable of capturing a magnetic field induced by a primary current flowing through the phase conductor, and a detection winding (30) wound around the magnetic core (20) so as to detect the magnetic field induced by the primary current flowing through the phase conductor. A secondary voltage is induced from the induced magnetic field and an output voltage that can be used to power an electrical system is delivered to the terminals of the windings. It comprises a heterogeneous magnetic circuit to induce an asymmetric magnetic flux flow in the magnetic circuit and to maximize the output voltage of the detection winding (30). In one variation, the magnetic core (2 |
