A single-phase 1-MVA 20kV/200v transformer has a short-circuit current which is the 20 times the rated current in the transformer, all the components are neglected except for the leakage reactances. 1) Calculate the rated primary current. 2) Calculate the primary short-circuit current. 3) Calculate the total reactance referred to the primary side. 4) if a pure resistance load with rated power is connected and the load voltage is the rated voltage, calculate the source voltage. 5) If a pure inductance load with rated power is connected and the load voltage is the rated voltage. calculate the source voltage. 6) If a pure capacitance load with rated power is connected and the load voltage is the rated voltage, calculate the source voltage 7) Calculate the voltage regulation and compare the results of 4-5-6 and comment on the results.
