Question: the nameplate on a 50mva 60hz singlephase transformer indicates that...

Question details

Q1- The nameplate on a 50-MVA, 60-Hz single-phase transformer indicates that it has a voltage rating of 78-kV:86-kV. An open-circuit test is conducted from the low-voltage side, and the corresponding instrument readings are 8.0 kV, 39.6 A, and 86.2 kW. Similarly, a short-circuit test from the low-voltage side gives readings of 4.53 KV, 321 A, and 77.5 kW. Write a MATLAB Script whose inputs are the rating (voltage and kVA) and rated-load, unity-power- factor efficiency of a single-transformer and whose output is the transformer rating and rated-load, unity power-factor efficiency when connected as an autotransformer.
