A 200-kVA, 480-V, 50-Hz, Y-connected synchronous generator with a rated field current of 5A was tested, and the following data were taken:

1.VT,OC at the rated IF was measured to be 540V

2.IL,SC at the rated IF was found to be 300A

3. When a DC voltage of 10V was applied to the two of the terminals, a current of 25A was measured

Find the values of the armature resistance and the approximate synchronous reactance in ohms that would be used in the generator model at the rated conditions.
