Abstract

In a system having primary conductor sections supplied with alternating current by respective feed-in devices, and having at least one mobile part, and in a method for operating such a system, in which the mobile part has a secondary winding, in particular on its underside, which is able to be, in particular is, inductively coupled with one of the primary conductor sections, the feed-in devices inject respective alternating currents of different frequencies into the primary conductor sections, and the mobile part has a device for acquiring the frequency of the alternating current injected into the primary conductor section inductively coupled with the secondary winding.
