Instabilities in multi-strand AC superconducting cables caused by longitudinal magnetic field with transverse magnetic field

In multiply-twisted AC superconducting cables, strands are exposed to magnetic field with longitudinal and transverse components. The influence of such components of the magnetic field on the AC quench current degradation is investigated. The internal magnetic field is calculated in various types of...

Zusammenfassung:In multiply-twisted AC superconducting cables, strands are exposed to magnetic field with longitudinal and transverse components. The influence of such components of the magnetic field on the AC quench current degradation is investigated. The internal magnetic field is calculated in various types of cables and a winding. The AC quench current was measured in the bias magnetic field with longitudinal and transverse components simulating the internal magnetic field in the multiply-twisted cables. The influence of such a magnetic field on thermo-magnetic instabilities is evaluated.< >
