  • Publication number: 20110089767
    Abstract: A method for measuring a capacitance using a capacitance meter. The capacitance meter includes an AC power source with a controllable frequency which is fed to a capacitor to measure its capacitance. A first measurement of the capacitance is performed by the capacitance meter using a first frequency. When the first measurement of the capacitance indicates the capacitance is below a threshold capacitance a lower capacitance measurement is performed in the capacitance meter, using a second measurement of the capacitance using a second frequency. When the first measurement of the capacitance indicates the capacitance is above a threshold capacitance, a higher capacitance measurement is performed in the capacitance meter, using a second measurement of the capacitance using a third frequency, the third frequency being lower than the second frequency.

  • 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.

  • Patent number: 7193495
    Abstract: A magnetically influenced current or voltage regulator includes a body of an anistropic magnetisable material that provides a closed, magnetic circuit. A first electrical conductor is wound around the body along at least a part of the closed circuit for at least one turn which forms a first main winding. At least one second electrical conductor is wound around the body along at least a part of the closed circuit for at least one turn which forms a control winding. The winding axis for the main winding is at right angles to the winding axis for the control winding. Orthogonal magnetic fields are generated in the body when the first main winding and the control winding are excited. A characteristic of the anisotropic magnetisable material relative to a field in the main winding is controlled by means of a field in the control winding.
