    摘要： A superconducting winding includes a pair of superconducting winding sections electrically connected at a node and bypass circuitry connected between the node and electrical ground and configured to allow current to flow to electrical ground when a voltage across the superconducting winding exceeds a predetermined threshold voltage. In certain embodiments, the bypass circuitry includes a switching device (e.g., zener diode) having an open position and a closed position, the switch in the closed position to allow current flow when the voltage across the superconducting winding exceeds the predetermined threshold voltage.

    摘要： A cooling device for cooling a stator of the type having windings, electrically insulated from each other including a cooling member, thermally coupled to an external surface of the windings. The cooling member has at least one passage extending through the member to receive a coolant from an external source. Because the passage for receiving the coolant is insulated from the high voltage stator conductors, water having ions (e.g., fresh water) can be used as the coolant for cooling the stator. Allowing the use of fresh water offers tremendous advantages in settings where deionized water is not readily available and eliminates the cost of a water deionization system.

    摘要： The invention features a system for connection to a utility power network. The system includes a reactive power compensation device (10) coupled to the network and configured to transfer reactive power between the utility power network and the reactive power compensation device; a capacitor system (50a, 50b) configured to transfer capacitive reactive power between the utility power network and the capacitor system; an electro-mechanical switch (52) for connecting and disconnecting the capacitor system to the utility power network; an interface (56) associated with the electro-mechanical switch; a controller (60) configured to provide control signals for controlling the electro-mechanical switch; and a communication channel (54) for coupling the controller to the interface associated with the electro-mechanical switch. The electro-mechanical switch, interface, controller, and communication channel together are configured to connect or disconnect the capacitor system from the utility power network within about three line cycles or less of the nominal voltage frequency when a fault condition is detected on the utility power network.

    摘要： A superconducting coil includes a first superconductor formed of an anisotropic superconducting material for providing a low-loss magnetic field characteristic for magnetic fields parallel to the longitudinal axis of the coil and a second superconductor having a low loss magnetic field characteristic for magnetic fields perpendicular to the longitudinal axis of the coil. The first superconductor has a normal state resistivity characteristic conductive for providing current limiting in the event that the superconducting magnetic coil is subjected to a current fault.
