Problem 2:

A three-phase transformer bank (1-phase transformers) is to handle 30 MVA and have a primary voltage of 115kVLL and a secondary voltage of 4.16kVLL. Find the rating of each individual transformer in the bank (high side voltage, low side voltage, transformer turn ratio, and apparent power rating of each transformer) if the bank is connected:

  • Wye-Wye
  • Wye-Delta
  • Delta-Wye
  • Delta-Delta
  • Draw winding connections for (a)-(d) (NOTE: This step does not need to be done in MATLAB). Assume all delta connections are 1-2Δ.
