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...

A balanced three-phase source with a 208 V rms (line-to-line) is delivering power to a balanced Y-connected load with phase impedance Z1 = 4 + j 3 Ohms in parallel with a balanced delta-connected load with phase impedance Z2 = 7.5 + j 6 Ohms. Calculate the active (real) and reactive (imaginary) powers delivered by the source. Draw the power triangle. What is the power factor of the combined load?
