Simulation short circuit test on 225kVA three phase Transformer

Core structure rectangular, windings copper, cooling ducts in between windings outside the core window. This is a finite element computer calculation using ANSYS simulation computer software.

  • Transformer ratings:
  • Input 415V- output 208V (phase – phase) 50hz
  • Rating: 225 kVA rating with 2% impedance
  • Vector DY
  • Dry type construction

Notice the Following:

  • Large distortion on the outside phases
  • High stress on the linear section of rectangular windings
  • Allows the use of computer simulation to eliminate actual short circuit testing
  • The simulation was part of a Research & Development project carried out by the Tortech engineering team.
