Modeling the limiting performance of resistive superconductor fault current limiters for 2G HTS tape
Firat University Journal of Experimental and Computational Engineering, 2022 Fault currents in power systems force valuable power system elements thermally, electro-dynamically and electromagnetically. Due to the increase in fault current levels, the installation of components resistant to fault currents and the damage of these ...
