This study focuses on investigating the dielectric breakdown characteristics of high-temperature superconducting (HTS) coils, which are increasingly used in various applications such as superconducting cables, superconducting fault current limiters (SFCLs), and superconducting particle accelerators. The research aims to understand how electrical breakdown, induced by high electromotive force and local quenching, can weaken the dielectric stability of HTS magnets. The dielectric experiments were conducted under different vacuum conditions and gaseous helium conditions, and an empirical formula for the electrical insulation design of HTS magnets was developed. Finite element method (FEM) analysis was also performed to simulate various conditions that may cause electrical breakdown, confirming that breakdown could occur at turn-to-turn and layer-to-layer of HTS magnets. As a result, it was confirmed that the magnitude of the induced electromotive force or quench voltage that could cause electrical breakdown of the HTS magnets under various insulating medium conditions such as gaseous nitrogen (GN2), gaseous helium (GHe), and vacuum was deduced.
