Critical current properties in HTS tapes
Physica C: Superconductivity, 2003Abstract The author’s recent studies on the critical current properties in Bi-2223 multifilamentary tapes as well as YBCO coated IBAD tapes have been reviewed. Extended electric field vs. current density ( E – J ) characteristics were studied over wide range of temperature, T , magnetic field, B , and angle, θ . Based on the analysis of statistic

Over-Current Testing of HTS Tapes
IEEE Transactions on Appiled Superconductivity, 2005High-temperature superconducting (HTS) transmission cables are subjected to short-circuit fault currents 10 to 30 times the normal operating current and lasting up to 15 cycles. These over-currents will drive the HTS conductor normal and generate heat during the fault.

Homogeneous Current Distribution in Multi-laminated HTS Tape Conductor for Pancake Coil of SMES [PDF]
Physics Procedia, 2012 A multi-laminated HTS tape conductor has been recently developed to fabricate large pancake coils such as SMES. If the HTS tapes are simply laminated to form the conductor, the current distribution in the laminated tape conductor of the coil is ...

Investigation of HTS Tape Stacks for Levitation Applications
IEEE Transactions on Applied Superconductivity, 2016Currently, high-temperature superconductor (HTS) bearings are most commonly designed with bulk REBa 2 Cu 3 O 7-x (REBCO), but these HTS bulks have several drawbacks, such as brittleness and the complexity of sample preparation. An alternative for levitation systems is to use stacks of REBCO coated conductors (HTS tapes).

HTS Tapes Selection for Superconducting Current Limiters
IEEE Transactions on Applied Superconductivity, 2017The superconducting fault current limiters (SFCLs) are highly effective solutions to reduce fault current in electric power system. The process of quenching may occur in all superconducting devices, but in fault current limiters this process must be fully controlled.

Relaxation of Levitation Force of a Stack of HTS Tapes
IEEE Transactions on Applied Superconductivity, 2016Nowadays, magnetic bearings are used to design motors, generators, separating platforms, and flywheel energy storage systems. High-temperature superconducting (HTS) magnetic bearing construction is based on YBa 2 Cu 3 O 7-x (YBCO) bulks through its ability to capture and hold significant magnetic field for a long time.

Levitation Force of Magnetized HTS Tape Stacks
IEEE Transactions on Applied Superconductivity, 2017High-temperature superconductors (HTS) have the significant potential of magnetic-force-based applications. Nowadays, wide spread of coated conductors tapes (CC-tapes) enables the use of HTS stacks in levitation applications. For the development of CC-tapes-based bearings and transportation systems, it is important to have information on stability of ...

The Levitation Force Characteristics of Stacked HTS Tapes
2020 IEEE International Conference on Applied Superconductivity and Electromagnetic Devices (ASEMD), 2020High temperature superconducting (HTS) tapes can be stacked into a block structure and be used in HTS magnetic levitation systems. This paper proposes a simulation method based on H-formulation to study the levitation force characteristics of the stacked HTS tapes on the permanent magnet guideways (PMG) in Comsol Multiphysics.

Stresses and strains in multi-filament HTS tapes
IEEE Transactions on Appiled Superconductivity, 1999High temperature superconducting tapes are now commercially available for practical applications such as magnets and cables. However, still today the published data on strength and allowable deformation limits of these tapes are not altogether in agreement. Definitions and concepts with regards to the stresses and strains in HTS tapes under deformation
