Question

PLEASE SO PART C, THANK YOU WILL RATE.A single-phase transformer with a 5:1 turns ratio is connected to a 600 V voltage source on the primary side, and a 5 Ω resistor on the secondary. A current of 22 amps of current is measured to flow through the 5 Ω resistor on the secondary side. The real power flowing into the transformer primary is measured at 2500 W. You can neglect Lm and Rc (the magnetizing inductance and core loss resistance) in your answers a) Draw the equivalent circuit that adequately represents the non-ideal transformer behaviour? b) With the resistor connected (switch closed), what is the voltage on the secondary side? Based on this, determine the voltage regulation (assume 22 A on the secondary is full load) Based on the measurements taken, determine the series impedance Zs, then Rs and Ls (the series winding losses and leakage reactance) c)
