    Abstract: A connector for connecting a power cable with solid insulation to medium-voltage equipment comprising a connection device arranged in an angular housing. The connector comprises a screwable pin contact which is connected to the cable core. The device comprises a guide sleeve, fixed in the angular housing, with an extension made in the shape of a jaw, into which sleeve the cable core is inserted, and a clamping block, into which the pin contact is threaded. The inner end of the pin contact makes contact with the jaw such that, when tightening the pin contact, the cable core is squeezed between the clamping block and the jaw. The angular housing comprises an outer semiconducting layer, the end of which, connecting onto the cable, is capable of being folded up. The connector is removable fixed to the medium-voltage equipment with a clamping device which is arranged in one piece of resilient wire.

    Abstract: PCT No. PCT/SE97/00495 Sec. 371 Date Oct. 27, 1998 Sec. 102(e) Date Oct. 27, 1998 PCT Filed Mar. 24, 1997 PCT Pub. No. WO97/36363 PCT Pub. Date Oct. 2, 1997A gas-insulated semiconductor valve for high voltage power has an elongated valve stack with a plurality of semiconductor elements. The valve stack is provided with electrostatic shields for reducing the stresses on the insulating medium. The shields comprise a plurality of annular shields distributed along the longitudinal axis of the valve stack. The shields are arranged in planes which are substantially perpendicular to the longitudinal axis of the stack and surround the valve stack. The curved part of each shield has a substantially constant radius of curvature.

    Abstract: Connection arrangements are employed for reducing the effect of third-hannonic voltages in case of direct connection of AC machines to a three-phase distribution or transmission network, wherein the stator winding of the AC machine is Y-connected and wherein the neutral point of the winding is available. An exemplary embodiment employs a suppression filter turned to the third-harmonic, with an overvoltage protection device arranged between the neutral point and ground of the power network.

    Abstract: A device for non-contacting measurement of a measuring object is provided. The device includes at least one pair of associated coils, including a transmitter coil and a receiver coil. The transmitter coil generates a time varying magnetic field. In the receiver coil, a voltage is induced. The voltage is dependent on the location of the transmitter coil, the receiver coil and a measuring region of a measuring object. The device comprises a U-shaped structure with two branches. A retaining part is arranged between these branches. The transmitter and receiver coils are fixed to the branches of the U-shaped structure and the measuring object is intended to be arranged centrally in the opening of the U-shaped structure.

    Abstract: The invention relates to a method for supervising the functioning of a plurality of valve units, a system for performing the method, a control unit and a control assembly for cooperation with the control unit. Each valve unit in the system comprises a semiconductor element (THY1-THYN) and a control unit for controlling the semiconductor element. The control unit comprises a trigger order input for receiving a trigger order (FP), an indication output for emitting a first indication signal (TP) and a trigger signal output (100) for emitting a trigger signal to the semiconductor element. The method comprises the steps: detecting a positive forward voltage (UT) across the semiconductor valve, generating a first indication signal (IP) when the forward voltage (UT) exceeds a first threshold value (U1), generating a trigger signal upon detected receival of the triggering order signal (FP), and the step: generating a second indication signal (SSTP) when the forward voltage (UT) exceeds a second threshold value (U2).

    Abstract: A method and a device, during casting of metal in a mould (12) which is open in both ends in the casting direction and where, in the mould, an incoming primary flow of melt is braked and split and the secondary flow is controlled by means of static or periodic low-frequency magnetic fields acting on the melt, for ensuring that the upper surface of the melt, the meniscus (17), does not solidify by the provision of at least one inductive heater (18) adapted to apply a magnetic alternating field which acts on and develops heat in and/or compressive forces acting on the melt close to the meniscus.
