    The purpose of this work is to study a de reactor type fault current limiter(FCL) using high temperature superconducting(HTS) coil which is connected with the secondary winding of a transformer through a diode bridge. The high temperature superconductors provide the advantages of a higher temperature operation and they are preferably applied to the de reactor type fault current limiters, where a superconducting coil can be operated at both low voltage and de current. We propose a de reactor type three-phase FCL incorporating only one HTS coil and present its test result. Three-phase FCL for 6.6 kV-2000 A requires one HTS coil of 2.9 MJ.

    HTS wires of various structures and synthesizing processes are being developed for power apparatus applications in Super-CM project. AC transport current losses of four of those wires were measured by an electric method using a lock-in amplifier, Measured wires are a Bi2212 rod fabricated by the laser pedestal growth method, a Y123 tape fabricated by the pulsed laser deposition and multilayered Bi2223/Ag sheathed wires of square and tape shapes. In this paper, based on measured data, dependence of AC transport current losses of HTS wires on their structures and synthesizing processes is discussed.

    AC loss characteristics of multifilamentary NbTi AC wires under AC external magnetic field were experimentally and theoretically investigated. We measured AC transport current losses of AC wires with various twist pitches under the AC external magnetic field which included longitudinal and transverse components. It was shown by the measurement that the AC transport current losses decreased with decreasing the twist pitches when the external and self longitudinal fields were in the same direction. The measured dependence of the AC losses on the twist pitches and the applied longitudinal field component were well explained by our previously derived model. We also theoretically estimated the AC losses caused by the longitudinal and azimuthal field components. It was found that the AC losses can be substantially reduced by properly selecting the twist pitch and the external longitudinal field component.

    In the paper we report the experimental results for ac losses in HTS coil carrying ac transport current. The tests of ac losses mere performed by the electrical method at 77 K and 4.2 K. The HTS tape consists of 55 multi-filamentary silver-sheathed BSCCO 2223 tape without twisting. The sample coil was made by the React and Wind method using insulated tape conductor. The coil has the inner diameter of 46 mm, outer diameter of 87 mm, height of 14.5 mm, and the number of turns is 300 turns. The measured ac losses were compared with the conventional theory based on the critical state model. In the region of low transport current, the theoretical results agreed well the experimental results. We also investigated the distribution of the sc losses in the coil to study the effects of magnetic field distribution on ac losses.

    We have measured the self magnetic field AC losses of a typical AC multifilamentary superconducting wire in an AC transverse external magnetic field at 50 Hz. The experimental results show that the self field AC losses are much higher than the transverse field AC losses and strongly depend on the phase difference between the transport current and the background field. We derived a theory to estimate the dependence of the self field AC losses on the phase of the external field based on the critical state model. In the paper, the measured loss characteristics are compared with the theoretical results. The theoretical model well explains the measured loss characteristics.

    Studies of the current-voltage characteristics of typical superconducting wires under static and dynamic conditions up to 50 Hz frequency have revealed much higher instantaneous local loss power densities in an external DC magnetic field than those which occur by magnetization in a transverse AC magnetic field. In this paper, the measured loss characteristics are compared with theoretical ones derived from the critical state model, and the self field AC losses are also estimated. Possible errors that can result by applying the critical state model are discussed.

    The paper presents results obtained in the study of the current - voltage characteristics, critical and quenching currents as well as of the AC transport current and magnetization losses in four series of fine filament NbTi composites prepared by Showa Electric Wire & Cable Co., Japan. Complementary measurements have been made also on a commercially available type T AC superconducting wire produced by GEC Alsthom Company, France.
    The samples differ in filament diameter, matrix thickness between filaments and in the number and structure of filament bundles in the composite. In two series of samples barrier type artificial pinning centers have been introduced to increase J(c) and decrease the normalized magnetization losses. The conclusions concerning the optimization of multifilamentary composites and cables for AC use at low working magnetic field are briefly reviewed.

    Current-voltage characteristics of two superconducting wires for a.c. use in d.c. magnetic fields up to 1 T were studied. They were measured with d.c. transport current as well as with sinusoidal a.c. transport current at frequencies up to 50 Hz. Voltage signals due to the self-field effect were obtained and analysed. The measured self-field voltage is also compared with that obtained from calculations based on the critical state model. The self-field losses were estimated by numerical integration of the measured self-field voltage multiplied by instantaneous transport current.

  • VERY SENSITIVE ELECTRIC METHOD FOR AC LOSS MEASUREMENT IN SC COILS

    Because the inductive component of the voltage across a superconducting coil is 10(2) - 10(4) times larger than its loss component, in the most of electric methods for AC loss measurements compensating voltage proportional to partial derivative I/partial derivative t is needed, I being the current in the coil.
    This paper presents a description of an air-core transformer whose mutual inductance M can be smoothly changed in a very large interval and the secondary voltage of which has a negligible phase shift with regard to partial derivative I/partial derivative t in the primary as well as strongly suppressed noise voltage.
    It also describes a very sensitive method of measuring AC losses in superconducting coils based on the use of such mutual as well as of a selective nanovoltmeter. This method eliminates the need off an integrator with small drift and phase shift error, of a high resolution voltage divider with sliding contact and of a shunt resistor with small phase shift which are required by other analog electric methods.
    Experimental compensating coil and their parameters as well as AC Toss measurements in different superconducting coils are also described.
