Someone gave me this advise. I found useful. However I did all chapters and all chapter end questions. It was helpful.
Chapter 1---show you how to use the per unitChapter 2 ---If you don't remember the basics of KVL, KCL etc.Chapter 3, 4, 5....i barely touch it....is DC generators and motors...so no need to worry about those.Chapter 7-12 ---needs to be studied....discussed power and transformers.---this is like 45% of the exam.Chapter 13-15--needs to be studied....it discussed motors....when i study for the PE i concentrate on motors not generators....generators is the same thing but reverse.Chapter 17---needs to be studied... synchronous motor.Chapter 21--needs to be studied....power electronics....from power electronics you just need to know if the input wave look like this how would look the output wave.Chapter 24- gives you an understanding of how the power is generated....i read it... interesting chapter.Chapter 25 & 26- Transmission and distribution.....these are important chapters that needs to be studied....in fact there was a question in the real exam that i answer the question from one of those chapters.Chapter 30 - Harmonics you at least need to know what cause it....what is a 2nd order 3rd order...etc. I wouldn't skip this one.
