“…High current density of superconductive wires enables the realization of their application. [1][2][3][4]. Due to low resistance in normal operation of power grid, high resistance and short response time in fault limitation operation , SFCL (superconducting fault current limiter) can effectively limit the fault current, and play an important role in the electrical power system.…”

A new type S uperconducting Fault Current Limiter (S FCL) for dc applications is proposed. This SFCL consists of a current transmission/ limiting coil, an iron-core, and a set of superconductor rings. The superconductor rings are placed between the current transmission/ limiting coil and the iron-core. For application, the current transmission/ limiting coil is connected in series to a dc transmission line. During normal power transmission, magnetic flux coupling between the current transmission/ limiting coil and the iron-core is prevented by the magnetic shielding of the superconductor rings, and the current transmission coil has low impedance. Because of shielding effect of the superconductor rings iron core has high permeability at the beginning of short circuit, current limiting coil can effectively limit fault current rise. When the fault current reaches a certain level, the superconductor rings will quench and the shielding effect is greatly reduced. The current limiting coil strengthens the coupling with the iron core, increases the inductance, and will suppress the further increase of the fault current.A laboratory proof of concept prototype was made to demonstrate the feasibility of the idea. Experiments have been carried out with the prototype. In this presentation, we will introduce the detailed information of the principle, the prototype, and the experimental results. In addition a design of the new type DC S FCL is installed in a  160kV HVDC system.  Index Terms-DC power system, Fault current, Magnetic shielding, and S FCL S uperconducting Fault-Current Limiters

“…Oxide ceramics of the Y-Ba-Cu-O (YBCO) system are an interesting class of materials that has not yet been studied in the framework of SBS [6,[19][20][21]. YBCO, owing to their superconducting properties, have been applied in nanoscale molecular circuits [22], high-frequency electronics [23,24], power transmission [25], transformers [26], generators [27], and motors [28].…”

This study proposes a novel solution blow spinning technique (SBS) for fabricating YBCO ceramic nanofibers. The precursor solutions were obtained from Y, Ba, and Cu metallic acetates (Ac) and poly(vinyl pyrrolidone) (PVP, Mw = 360,000). Ac:PVP concentrations of 1:1 and 5:1 were tested, resulting in ceramic nanofibers with average diameters of 359 and 375 nm, respectively. X-ray diffraction confirmed the formation of a pure phase of YBa2Cu3O7-x. This is the first study to use SBS for fabricating YBCO nanofibers, and this technique shows promise for obtaining high-quality ceramic materials.

“…Among the high critical transition temperature superconductors, YBa 2 Cu 3 O 7−δ (YBCO) has been extensively investigated and is considered to be the most promising cuprate [1]. In fact, YBCO is already being investigated for use in power transmission [2][3][4], motors/generators [5], transformers [6,7], and high frequency electronics [8][9][10] applications.…”

YBa2Cu3O7−δ (YBCO) nanowires with critical transition temperature Tc = 91.7 K were synthesized by an electrospinning process with the use of sol–gel precursors. A homogeneous polymeric solution containing Y, Ba, and Cu acetates was electrospun, resulting in collections of randomly oriented nanowires as well as bundles of aligned nanowires. Fully crystallized YBCO nanowires were obtained after calcination at temperatures as low as 820 °C. The morphology, microstructure, and crystal structure were investigated, and the diameters of the polycrystalline nanowires varied between 120 and 550 nm depending on the viscosity of the precursors. Thinner individual wires, with diameters in the 50–80 nm range, were synthesized with a single grain structure across the entire wire cross-section.
