1. A device for recovering electrical energy, comprising at least one ferromagnetic cable which is helically wound around at least a portion of a power conductor in order to form a magnetic system which is capable of sensing the magnetic field induced by a current passing through said power conductor, and means for generating an induced voltage from this magnetic field which can be utilised, characterized in that said at least one ferromagnetic cable is constituted by an assembly of unitary strands produced from ferromagnetic material, assembled in the form of a stranded wire and disposed to provide said at least one ferromagnetic cable with flexibility in all directions, enabling said at least one ferromagnetic cable to be wound around said power conductor whatever the diameter of said power conductor, and in that said means for generating an induced voltage form an integral part of said at least one ferromagnetic cable.
