Influence of the HTS Winding Tape on Limiting the Transient Currents in Superconducting Transformers
The article presents an extended computer model of a HTS (high temperature superconducting) 21 MVA 70/10.5 kV transformer with severalfold compound windings, based on a verified PSpice model of 10 kVA transformer with single windings. Two superconducting

Current sharing of parallel SiC MOSFETs under short circuit conditions [PDF]
Device-to-device parametric variations (e.g. threshold voltage V TH , gate resistance R G and junction temperature T J ) can cause variations in the short-circuit currents conducted through parallel-connected devices.

Equivalent modeling method of induction motor contribution to short-circuit current
When a short-circuit fault occurs in the power grid, induction motors in the distribution network will contribute to the short-circuit current. Accurate short-circuit current calculation of the motors requires detailed modeling of distribution network ...
