Abstract: The present invention relates to a rotating asynchronous converter and a generator device. The converter comprises a first stator connected to a first AC network with a first frequency f 1 , and a second stator connected to a second AC network with a second frequency f 2 . The converter also comprises a rotor means which rotates in dependence of the first and second frequencies f 1 , f 2 . The stators each comprises at least one winding, wherein each winding comprises at least one current-carrying conductor, and each winding comprises an insulation system, which comprises on the one hand at least two semiconducting layers, wherein each layer constitutes substantially an equipotential surface, and on the other hand between them is arranged a solid insulation.

Abstract: A rotating electrical machine and method for making the machine, where the machine includes a high-voltage stator winding and elongated support devices for supporting the winding. The machine and method employ an arrangement of cable that is made of inner conductive strands, covered with a first semiconducting layer, which is covered with an insulating layer, which is covered with a second semiconducting layer. The cable is wound in slots in the stator such that separate cable lead-throughs are positioned in specific arrangements with respect to each other and in slots of the stator. The arrangement of the cable in the stator protects the integrity of the respective components in the cable and particularly the second semiconducting layer.

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.
