  • Power transmission system
    Patent number: 8558416
    Abstract: The invention relates to a power transmission system for transmitting electrical power from a power source to a load. The system comprises a capacitive and lossy transmission line or cable and a transformer device. The transformer device comprises a magnetic core and a first winding wound around a first axis of the magnetic core. The first end of the transmission line or cable is connected to the power source and the second end of the transmission line is connected to the transformer device. A second winding wound around the first axis of the magnetic core, where the second winding is connected to the load. A control winding is wound around a second axis of the magnetic core, where the first axis and the second axis are orthogonal axes to that when the first winding, the second winding and/or the control winding are energized, orthogonal fluxes are generated in the magnetic core.

  • Load symmetrization with controllable inductor
    Patent number: 7259544
    Abstract: A method for compensation and symmetrization of a three-phase system with a single-phase load is provided. At least one variable inductor for connection to the three-phase system is employed in the method. The inductor's inductance is adjusted to obtain a resistive single-phase load and/or a three-phase load which draws balanced line currents. A device and a system for compensation and symmetrization by means of variable inductors is also provided.
