Abstract
This paper presents the results of studies of non-equilibrium states in ribbon high-temperature superconductors under pulse current loading. To study transient processes in a superconductor at critical current loads an experimental stand was developed, which allows to perform visualization of thermal processes in the composite at critical current loads with high temporal resolution. The dynamics of thermal processes in HTS tape under current loads was investigated, the peculiarities of thermal processes leading to the change of liquid refrigerant boiling modes were shown. The process of HTS sample fracture under supercritical current load was studied on a millisecond scale.
