Abstract: The possibility of using high-temperature superconductors of the second generation in protective resistors (HTS resistors) for electrical equipment is considered. It is proposed to use mesh fiberglass electrical insulation in the HTS resistors to ensure the efficiency of the heat sink and maintain a stable overloaded operation. Physical modeling of such resistors was performed, which showed the preservation of their overload capability and the suppression of thermal instabilities due to the presence of mesh insulation.

Keywords: high-temperature superconductor, protective resistor, mesh insulation, refrigerant, resistive state, thermal breakdown.
