Simulations of the quench-behaviour of coated conductors with hot-spots

The calculated results of thermal-electric simulations of coated conductors with hot-spots are presented. Multiple 3D-simulations were made with and without hot-spots. As boundary conditions Liquid Nitrogen (LN2) cooling and an overcritical current density are used. The design of the model is based on actual commercial available 2nd Generation High-Temperature-Superconducting (HTS) tapes. The commercially available 3D finite element program ANSYS®, which was enhanced with a superconducting element, is used for the simulations. This work will help to clarify the quench behaviour of HTS-tapes with hot-spots and is especially interesting for current limiting applications.
