Abstract
The resistive SFCL (superconducting fault current limiter) is a superconducting device which may operate both in superconducting state and in normal conducting (resistive) state. The paper presents FEM numerical model (in FLUX2D) of resistive SFCL made using Bi-2212 bifilar coil (NEXANS) cooled by pool boiling cooling technique (liquid nitrogen, 77 K). Real geometry of resistive SFCL is replaced by equivalent, due to energy and current density, geometry of numerical model. The electro-thermal numerical model of resistive SFCL can be used to estimate the energy and maximum temperature in limiter and the time to switch off the current to protect against damage.
