    Abstract: 16 Film capacitors have a thin carrier film (1) as dielectric. The surfaces of the carrier films are provided with conductor layers (2) - serving as electrodes - made of metal or made of a nonmetallic conductor. It the capacitor is charged during operation, electric fields with large field strengths can arise at the edges of the conductor layers (2), which can lead to breakdowns. The invention is essentially distinguished by the fact that an edge zone coating (3) is present at the edges of the electrode- forming conductor layer (2), which edge zone coating is only partly charged in the time periods - for example of the alternating-current period - which are critical for changes in the applied voltage. To that end, the edge zone coating of the film must have a surface conductivity which is less than the surface conductivity of the conductor layer. The only partial charging of the edge zone coating has the result that the potential profile has scarcely any discontinuities and large field strength increases can thus be avoided.

    Abstract: The arrangement has a coupling capacitor (8) in an earthed housing (10) and a connecting cable (9) with a conductor (20) and a screen (22). The conductor is connected to a point on a phase conductor of a current cable. The conductor of the connecting cable leads into the interior of the housing and is connected to the coupling capacitor. The conductor screen, of the connecting cable, is electrically connected to the housing.

Date Apr. 4, 1996A current limiting device including at least one superconductor and at least one nonsuperconducting shunt resistor in parallel with each superconductor. Each superconductor has a first main superconductor face in contact with a main shunt resistor face of a shunt resistor so as to form a compound conductor generally in the form of a meandering band having a band width greater than approximately 3.5 times the superconductor thickness. At least one insulator has opposing faces each in contact with a compound conductor. Multiple compound conductors are arranged such that current flows in opposite directions through adjacent compound conductors.

    Abstract: In a device for damping blade vibrations of an axial-flow turbomachine, the ends of the rotating blades form a seal toward the flow-limiting wall of a turbine casing. A ring of permanently magnetic material is attached to this flow-limiting wall of the turbine casing in the radial direction opposite the blade ends, which ring consists of at least one or more sectional rings of the same or different magnetic polarization. The blade ends are each provided with a cover plate which is made of a material which is a good electrical conductor.
