Claim 0:
1. A method of recovering electrical energy from a power cable comprising at least two phase conductors, the method comprising the steps of: installing around said power cable a magnetic core in the form of a torus, to form a magnetic circuit suitable for detecting a magnetic field induced by a primary current passing through the phase conductors of said power cable, equipping said magnetic core with a detection coil for inducing a secondary voltage from said magnetic field and delivering an output voltage at terminals of said detection coil, enabling different types of electrical systems to be supplied, said method further comprising the step of making said magnetic circuit heterogeneous in order to generate an asymmetrical magnetic flux flow within said magnetic circuit, enabling said output voltage to be maximized and thus obtaining a usable output voltage at the terminals of said detection coil.
