A method and device for insulation fault monitoring in ungrounded electrical networks. The method includes the following steps: measuring an insulation resistance, determining a responding value for the insulation resistance, and triggering a warning signal if the measured insulation resistance falls below the responding value, wherein the responding value is determined dynamically as a momentary responding value in a warning value establishment process downstream of the insulation resistance measurement.

Method for insulation fault monitoring with dynamic response characteristic

The present invention relates to a device for current measuring in power supply networks comprising transformers for measuring current, a signal processing apparatus arranged on a printed circuit board and screw fastenings for mounting the device. The cable ducts of the transformers are orientated parallel to the plane of the printed circuit board, which has openings flush to the cable ducts, and the screw fastenings are fastening tabs with mounting holes, spaced so standards-compliant mounting is possible. In an alternate embodiment, the cable ducts are orientated perpendicularly to the plane of the printed circuit board, the screw fastenings are constructed as an angle rail with cable outlets and standards-compliant mounting holes, and the printed circuit board is internally fastened on one side of the angle rail. In another alternate embodiment the transformers are installed with the printed circuit board in a common housing with fastening tabs and standards-compliant mounting holes.

The cockpit module of a vehicle has a cup holder which has an opening for receiving a drinking vessel, and an illumination device for illuminating the cup holder. The cockpit module also has a printed circuit board on which the illumination device is arranged. A motion sensor is preferably provided which recognizes an object approaching the opening of the cup holder and the state of occupation of the cup holder, so that the illumination device can be controlled in a definable manner as a function of the occupation and if an object approaches.
