15. A recovery device for recovering energy from a power cable comprising at least two phase conductors, said device comprising a magnetic core, in the form of a closed or open torus, positioned to be installed around said power cable and form a magnetic circuit capable of detecting a magnetic field induced by a primary current passing through said phase conductors, and a detection coil wound around said magnetic core, arranged to induce a secondary voltage from said magnetic field and deliver across said detection coil an output voltage for powering different types of electrical systems, wherein said magnetic circuit is heterogeneous to generate an asymmetrical magnetic flux flow within said magnetic circuit, to maximize said output voltage and to obtain a usable output voltage at terminals of said detection coil.
