2D and 3D Numerical Models of Inductive SFCL
The Superconducting Fault Current Limiter (SFCL) can be used to limit the short-circuit current level in electrical networks. The inductive SFCL works like a transformer with shorted secondary HTS winding. Because of the iron core, the inductive SFCL is not axially symmetrical and should be modeled in 3D geometry. On the other hand, the 2D modeling gives much more computational advantage, in comparison with 3D modeling. The paper explains in what case the 3D modeling of inductive SFCL can be replaced by much simpler 2D modeling.
