Abstract: A DC current path for DC power transmission includes a switchable element. An inductance is connected in series to the switchable element. When an interrupt scenario is detected, a resonance circuit is connected in parallel to the series connection of the switchable element and the inductance for charging a capacitance of the resonance circuit. An open state of the switchable element is effected and the resonance circuit is connected in parallel to the switchable element. By means of such arrangement and method, favorable fast interrupt times can be achieved.

Abstract: A high-voltage device includes a conducting element for conducting a high-voltage current and at least one transient reducing unit for reducing voltage peaks of existing propagating very fast transients (VFTs) by the generation of arcing. The transient reducing unit has at least one arcing occurrence surface. The at least one arcing occurrence surface of the at least one transient reducing unit is positioned in the vicinity of the conducting element such that arcing occurs between the transient reducing unit and the conducting element when the potential difference between the transient reducing unit and the transient conducting element is above a threshold value, such as at the occurrence of a very fast transient. A method is also provided for equipping a high-voltage device with the transient reducing unit.

Abstract: The disclosure relates to an electrical contact system for a switching device having a mating contact and a second contact. According to the invention, the second contact has a contact tulip, at the outer face of which a current transfer takes place to an annular part of the mating contact. Exemplary embodiments relate to, inter alia: additional current transfer at an inner contact-making face of the contact tulip to a pin-shaped part of the mating contact; mating contact with mating contact tulip for engaging with the contact tulip; and measures for improving the contact forces. Advantages include: tulip-in-tulip design with large contact face, high contact force, reduced number of contact fingers, reduced number of mating contact fingers, and improved adjustment tolerance; contact tulip acts as an arcing contact and at the same time as a short-term current contact.
