Abstract

In a system for an inductive energy transmission from a primary-conductor system, in particular a stationary primary conductor system, to a vehicle having a secondary winding, the secondary winding is inductively coupled with the primary-conductor system. The primary conductor is installed as a primary-conductor loop installed in elongated form, which has a feed conductor and a return conductor in a line section, in particular a return conductor that is installed parallel thereto, and the return conductor is electrically grounded in that at least one inductance is disposed between the return conductor and the electrical ground.
