Q1: For ideal transformers, can you explain the ratio between windings, current, and voltage. And explain the relationships of the ratios when the circuit is referred to primary and secondary. Show the proof.
Q2: Using the ideal transformer ratio, how do we find its referred( primary or secondary) impedance.
Q3: Show the proof for reactance and resistance when
referred to primary or secondary. Hint : R= a^2 * R , R/a^2
How do we know when to use these formulas?

transformers
Learning Goal: To understand the concepts explaining the operation of transformers.One of the advantages of alternating current (ac) over direct current (dc) is the ease with which voltage levels can be increased or decreased. Such a need is alwayspresent due to the practical requirements of energy distribution. On the one hand, the voltage supplied to the end users must be reasonably low for safety reasons(depending on the country, that voltage may be 110 volts, 220 volts, or some other value...

A three-phase Yy0 connected transformer has a nominal rating of 250 kVA and a voltage ratio 15:0.4 kV. After conducting the short-circuit test, where the secondary winding is short-circuited, it is found that the primary series resistance is 0.08 pu and the primary series impedance magnitude is 0.1pu. The effect of the parallel branch in the transformer’s equivalent circuit may be neglected. Explain what information ‘Yy0’ gives about the transformer. Draw the per-phase equivalent circuit of the transformer during the...

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...
