Abstract: A ring (4) of pref. Sm-Co magnetic material recessed in a housing (5) of austenitic steel in the wall of the turbine casing (1) is divided into three sections (7a-7c) with alternate polarity of magnetisation. The end (8) of each blade (2) is covered with a plate (3) of approximately rhombic form from the radial aspect, with acute-angled edges parallel to the direction of rotation. The plate is mfd. advantageously of Al whose good electrical conductivity favours the induction of eddy currents and damping of vibrations.

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.

Abstract: In order to limit overload currents in electric lines, caused by a short circuit for instance, the invention calls for a current limiter to be inserted in the electric line to limit the overload current to a given multiple of the nominal current. The simple, compactly designed current limiter has, disposed on each side of a disc-shaped insulator (1), a composite conductor made up of a high-temperature superconductor (3, 3') and a normal conductor (4, 4') connected flat against each other to give good electrical contact. Between the composite conductors and the insulator (1) is a chemically insulating buffer layer (2) made of 2- mu m-thick silver. Either the superconductor side or the normal-conductor side of the composite conductor makes flat contact with the insulator (1). The electrical resistance of the shunt (4, 4') should not be greater than that of the superconductor (3, 3') connected to it. Each composite conductor is meander-shaped in design and electrically connected so that the current in adjacent strips of the composite conductor flows in opposite directions.
