Abstract: The present disclosure provides an over-the-air measurement system for testing a device under test. The over-the-air measurement system includes an orthomode transducer (OMT) assembly having several separately formed orthomode transducer components that form at least two orthomode transducers. The orthomode transducer assembly has at least two output interfaces for feed antennas. Each of the at least two output interfaces is connected with one dedicated orthomode transducer. Two input interfaces are associated with each of the orthomode transducers. Each of the input interfaces merge into a corresponding waveguide transition that ends up in the respective orthomode transducer that is associated with the corresponding input interface. The several orthomode transducer components are stacked together linearly.

Abstract: An on-load tap changer uninterruptedly switches between winding taps of a tap-changing transformer. The on-load tap changer includes: at least one selector configured to preselect, in a powerless manner, a selected winding tap of the winding taps; at least one diverter switch configured to actually switch loads from a previous winding tap to a preselected winding tap of the winding taps; at least one toothed gearing comprising a first gearwheel and a second gearwheel, the first gearwheel being assigned to the selector, and the second gearwheel being assigned to the diverter switch; and a drive shaft, which is configured to be actuated by a motor drive. The first gearwheel and the second gearwheel are directly interconnected mechanically in such a way that the first gearwheel and the second gearwheel are simultaneously actuatable. The drive shaft is configured to drive either the first gearwheel or the second gearwheel.

Abstract: A selector (1) for an on-load tap changer, comprising a tap selector (2) with at least one selector arm (21, 22); a change-over selector (4), characterized in that the change-over selector (4) is actuated via at least one of the selector arms (21, 22) of the tap selector (2).

Abstract: A hollow conductor system is described which comprises at least two hollow conductor bundles and at least two connecting members. Each hollow conductor bundle comprises at least two hollow conductors separated by each other via a common intermediate wall. Each connecting member connects one hollow conductor of one hollow conductor bundle with a corresponding hollow conductor of the other hollow conductor bundle such that a void is provided between the connecting member and the adjacent connecting member and/or an adjacent hollow conductor. Further, a method for assembling a hollow conductor system is described.

Abstract: A switch comprises a first strip conductor and a second strip conductor, arranged orthogonally in a first plane. Moreover, the switch comprises a first switching conductor, having an orthogonally angled shape relative to the first plane. The switch comprises a switching actuator, which is mechanically connected to the first switching conductor and adapted to move vertically relative to the first plane to a first position and to a second position. The switching actuator is configured, so that in the first position, the first strip conductor is in contact with the first switching conductor and the second strip conductor is in contact with the first switching conductor, and so that in the second position, the first strip conductor and the second strip conductor are not in contact with the first switching conductor.

Abstract: A mounting device is provided for oscillatingly mounting a range extender, which consists of an internal combustion engine and a generator, on a body and/or a chassis of a motor vehicle by way of vibration-damping elements. At least two of the vibration-damping elements are integrated in load-carrying bearings and one additional one is integrated in a supporting bearing for supporting moments. The mounting device is characterized in that the vibration-damping elements of the mounting device at least for the load-carrying bearings are secured to the range extender, i.e. a first vibration-damping element is secured to the internal combustion engine and a second vibration-damping element is secured to the generator.

Abstract: The present invention relates to a contact unit for changing over between winding taps on a control winding of a tapped transformer. Such a contact unit can be used particularly preferably for electrical switchgear in high-voltage engineering, such as selector switches or changeover switches. A common feature of both kinds of device in this case is that the changeover between the winding taps on the control winding of the tapped transformer is accomplished without load current. The general inventive concept is to include the contact element of the contact unit in a separate contact housing, so that the contact element and the contact housing form a separate assembly and so that the contact housing, including the contact element, can be fixed in a recess provided in the contact mounting by means of a retaining element.

Abstract: The invention relates to a linear selector (1) for power-free preselection of tap contacts for a tapped transformer (100). The linear selector (1) according to the invention is cost-effective, simple and compactly constructed. The functions of a selector and a reverser are thus better connected. The linear selector (1) is constructed from a fine selector (2) and a reversing switch (3). The fine selector (2) and the reversing switch (3) are directly driven via a common gear unit (6).

Abstract: A method and a device for detecting an imminent rollover of a vehicle. The method comprises taking a series of images of the surroundings of the vehicle, in particular of the road ahead, with a camera; determining and tracking point features in the series of images; eliminating point features which are located on objects that move relative to the stationary surroundings of the vehicle; and computing at least one parameter of the rotational movement of the camera (roll, pitch and/or yaw rate) taking into account the remaining point features.
