Abstract: The invention relates to a current limiting method, a current limiting device (1), and a switchgear comprising such a device (1). According to the invention, liquid metal (3) is directed along a resistor element (5) for the current limiting path (31) so as to obtain arc-free current limitation for mains-related fault currents (i(t)). Examples of embodiments include, among other things: an electrical resistance (Rx) that increases in a non-linear manner in the direction of movement (x) of the liquid metal (3) for a smooth current limiting characteristic; a resistor element (5) in the form of a dielectric matrix (5) comprising channels (3a) for the liquid metal (3), and a combined current limiter-circuit breaker (1). Advantages include, among other things: arc-free, reversible current limitation and optional power shutdown; suitable also for high voltages and currents; fast reaction times; reduced wear; and maintenance-friendly.

Abstract: A method and device for determining the linear response of an electrical multi-port component (1) has an "estimation procedure" in which an estimated admittance matrix is determined by applying voltages to the ports of the component and measuring the response of the component. The estimation procedure can e.g. consist of a conventional measurement of the admittance matrix. The method further has a "measurement procedure" in which several voltage patterns are applied to the port. The voltage patterns correspond to the eigenvectors of the estimated admittance matrix. For each applied voltage pattern, the response of the component is measured. This allows to measure the linear response of the component accurately even if the eigenvalues of the admittance matrix differ by several orders of magnitude.

Abstract: The invention relates to a process and a device ( 1 ) for combined current limiting and circuit breaking and to a switchgear assembly with such a device ( 1 ). In a combined current limiter-circuit breaker ( 1 ) as claimed in the invention, a movable electrode ( 3, 3' ) on the one hand for current limitation is guided automatically along one resistance element ( 5 ) for the current limitation path ( 31 ) by an overcurrent-dependent electromagnetic force (F mag ) and on the other hand for circuit breaking is moved into a series arrangement with an insulator ( 8 ). Embodiments include the following, among others: Use of the Lorenz force for automatic current limiting; movable electrode ( 3, 3' ) implemented by liquid metal ( 3 ) or movable solid-state conductor ( 3' ); an electrical resistance (R x ) which increases nonlinearly in the direction of motion (x) for a gentle current limiting characteristic; and a resistance element ( 5 ) in the form of a dielectric matrix ( 5 ) with several channels ( 3 a) for the liquid metal ( 3 ). Advantages are among others: arc-free, reversible current limitation and current interruption, also suited for high voltages and currents, fast reaction times, low wear, and ease of maintenance.

Abstract: A method and an apparatus are disclosed for current limiting, as is a switchgear assembly having an apparatus such as this. Liquid metal is passed along a resistance element for the current limiting path, in order to achieve current limiting without any arcs for network-dependent short-circuit currents. Exemplary embodiments relate, inter alia, to: an electrical resistance, which rises non-linearly in the movement direction of the liquid metal for a soft current limiting characteristic, a resistance element in the form of a dielectric matrix having channels for the liquid metal, and a combined current limiter circuit breaker. Advantages are, inter alia, reversible current limiting and possibly current disconnection without arcs, also suitable for high voltages and currents, fast reaction times, low wear, and maintenance-friendliness.
