Abstract
The inventive system, of the conduction type, comprises: a pair of power supply tracks, comprising a so-called live conductive track (11), designed to be electrically connected to a voltage source, and a so-called neutral conductive track (12), for the current return, designed to be electrically connected to a reference potential (Vref), the neutral track traveling parallel to the live track on a first side thereof; and a protective conductive track (13), designed to be connected to a ground potential, the protective track traveling parallel to the live track (11) on a second side thereof, opposite the first side. The system is installed in a roadway such that the live, neutral and protective conductive tracks are flush with a surface (18) of the roadway (2).
