1. Explain why the SCC is linear.
2. Distinguish between Xs (unsaturated) and Xx (saturated). Which one should be used for higher accuracy in predicting the voltage regulation of a synchronous generator.
3. The synchronous reactance of an alternator is not constant over the entire operating range. What is this so? What value would you use?
4. In what manner does an synchronous motor adjust itself to an increasing shaft load?
5. State the assumptions made in the Potier method and the effect they have on the accuracy of voltage regulation as calculated by this method.
