Abstract: The invention relates to a power cable which comprises a central filler region (13) containing at least one conductor element (10), and additionally comprises at least one strip (16) arranged in said central filler region (13) in the vicinity of the conductor element (10). The cable is equipped with a winding-free energy recovery system (11) which supplies the strip (16) with electric current from the energy available in the conductor (10). The strip (16) has a plurality of elements which generate light from this electric current.

Abstract: A device for recovering energy from a single-phase power cable includes two phase conductors, a magnetic core, in the form of an openable torus, installed around the power cable to form a magnetic circuit able to pick up a magnetic field induced by a primary current passing through the phase conductors, a detection coil wound around the magnetic core, to induce a secondary voltage from the induced magnetic field and deliver across the coil an output voltage usable to power electrical systems, and a heterogeneous magnetic circuit to induce an asymmetrical magnetic flux flow in the magnetic circuit and maximize the output voltage of the detection coil.

Abstract: A device for recovering electrical energy includes a ferromagnetic cable helically wound around a portion of a power conductor , and disposed to form both a magnetic system which is capable of sensing the magnetic field induced by a current passing through the power conductor , and a way to generate a utilisable induced voltage from this magnetic field. The ferromagnetic cable is produced from an assembly of unitary strands produced from ferromagnetic material, these strands being assembled into the form of a stranded wire, each unitary strand behaving as a winding in which the induced voltage is induced, and the assembly of unitary strands forming an assembly of windings connected in parallel by way of connecting terminals provided at the ends of the ferromagnetic cable to recover the induced voltage.

Abstract: An openable toroidal current transformer is intended to close over at least one electrical conductor in which an electrical current to be measured circulates. The current transformer includes a magnetic circuit, and an electrically conducting coil wound around the magnetic circuit and electrically insulated from the magnetic circuit. The coil comprises a single winding or several distinct windings coupled in series. The magnetic circuit comprises a set of wires of magnetic material assembled in the form of a strand, allowing having uniform flexibility in all directions for the magnetic circuit.
