A single-phase transformer rated at 3000 kVA, 69 kV/4.16 kV, 60 Hz has a total leakage reactance Xp of 127 ohm, referred to the primary side. Calculate: a. The rated primary and secondary currents b. The secondary voltage if it is connected at full load of 2000 kW c. The voltage regulation from no-load to full load. Voltage regulation is given by: (E(no-load)-E (full-load))/E(full-load). d. The primary and secondary currents if the secondary is accidentally short circuited
