three-phase transformer is rated at 12 kV/135 kV, 100 MVA. It has the following equivalent circuit parameters (referred to the primary winding where appropriate) : • primary resistance R1 = 0.03 ohms, secondary resistance R2’ = 0.04 ohms • primary leakage reactance X1 = 0.1 ohms, secondary leakage reactance X2’ = 0.1 ohms • magnetising reactance XM = 16 ohms, core-loss resistance RC = 200 ohms. In your calculations, you should use the simplified equivalent circuit. i) The transformer is...
