Analysis of electromagnetic forces in high voltage superconducting fault current limiters with saturated core

“…These electromagnetic forces present as radial and axial forces [9][10][11]. Analysis of electromagnetic forces within a power-transformer is well established [9][10][11][12][13][14][15][16][17][18][19]. It was shown that such forces are potential sources for damage.…”

“…The problem faced when applying the models used in the analysis of power transformer on FCL design is that transformer models are generally based on round core-coil arrangement [9][10][11][12][13][14][15][16][17][18][19], whereas FCL cores and coils often have different geometries. Since fault current limiting for high voltage applications is a relatively new technology, the effects of electromagnetic forces in HTS FCL coils have never been reported.…”
