Abstract: A field control device for a high-voltage system includes a shielding element for field control, which can be connected to an electrical conductor of the high-voltage system in an electrically conductive manner and, when connected to the conductor, at least partly delimits a weak-electric-field spatial region. A cooling body, which can be connected to the electrical conductor in a thermally conductive manner and which is disposed within the weak-field spatial region, has an outer surface area which is greater than an outer surface area of the shielding element. A high-voltage system having the field control device is also provided.

Abstract: A method for switching an operating current in a meshed DC voltage network enables operating currents in a DC voltage network to be switched economically in both directions. At least one converter connected to the DC voltage network is controlled in such a way that a zero current is generated in a switching branch having a mechanical switch and the mechanical switch is actuated in accordance with the generated zero current.

Abstract: An arrangement has a coaxial resistor. The coaxial resistor is to be placed on an electrically conductive housing, and sensor lines of the coaxial resistor are to be guided through an interior of the coaxial resistor into the interior of the electrically conductive housing and to be connected to an electrical interface in the electrically conductive housing.

Abstract: A device controls a load flow in an alternating-voltage network. The device is distinguished by a module series circuit of two-pole switching modules that can be inserted in series into a phase line of the alternating-voltage network. Each switching module has an energy store and controllable power semiconductors that can be switched on an off and each switching module can be controlled in such a way that a switching-module voltage can be produced at the poles thereof, which switching-module voltage corresponds to a positive or negative energy-store voltage or a voltage having the value of zero. A control apparatus for controlling the switching modules is provided, which control apparatus is configured to control the switching modules in such a way that a periodic longitudinal voltage can be produced at the module series circuit. A method for controlling a load flow in an alternating-voltage network is performed by the device.
