The invention relates to a detection system for detecting electrically conductive foreign objects (F) in the area (3) between the primary winding and secondary winding of an inductive power transmission system, wherein the detection system also has at least one primary coil (LA) and at least one secondary coil (LB) which are coupled together, and that at least one primary coil (LA) and/or at least one secondary coil (LB) of the detection system is an integral part of at least one electric resonant circuit (LA-CA; LB-CB), wherein an electric source (7) energises at least one resonant circuit (LA-CA), and that a monitoring device monitors at least one electric variable on the secondary side and/or on the primary side of the detection system and effects the foreign object detection by means of the measured electric variable.
