  1. Books remaining: Power System Analysis Grainger $12 Handbook of Electric power calculations 4th ed $20 Protective Relaying Blackburn $70 $60 (dog chewed a little of the hardcover corner, still functions properly!)
  2. Bump, updated the list of books i have left.
  3. Yes they are, please send me a dm. thanks
  4. I passed first time taking the exam in October 2019. To add to the above, I think its important to sit down and just read through some of the common refrence material and pick out information that seems relevant. This does a few things, you of course learn the material but you also learn how to navagate the refrence material and even if you dont know exactly something is you will have a good idea on where to look. Practice exams are great and doing full sessions helps prepare you for the marathon of an exam, but learning theory and reading is the other side of the coin that needs to be do
  5. Yes everything is. I will update the post as i get rid of things
  6. I have the following books for sale, I will update this post as i sell things, please send me a DM with what you need.

  7. 1st time taker Pass NC! studied probably 400 hours. Congrats to those who have already seen they have passed and best of luck to those still waiting.
  8. Hey everyone, hope studying is going well. I have a question about the below problem. I must not be understanding what happens during a single phase to ground fault. I thought that one of the phases would be shorted to ground and the other two would be dead in this case IB & IC = 0. Based on the scenario below, i would think that a fault between a1&a2 would mean there is current flowing to ground through phase a but not through phase's b and c. I am also confused as to what is happening on the primary side. Thanks!
  9. I have a pretty basic question here but its tripping me up. A practice problem i was doing used P=V*I (thats the conjugate phase angle of V). Can someone explain this equation? Is it valid? I understand how and why we use S=VI* but i am uncertain of P=V*I. Thanks
  10. Sorry, i should've included the answer.
  11. Does anyone understand the following question? What is the purpose of the different areas? I just do not really understand the purpose of this question. Thanks!
  12. Would anyone be able to explain where the equation used in the soltion comes from this one:
  13. I noticed a new exam from EPG, what is the difference between this one and the "Power Full Exam'. Has anyone taken the new one? Recommend?
  14. I'm sure I'm just missing something simple here. This a part of the solution where the sequence current is converted into phase current. That equation does not match the equation used in the EPG study guide. The study guide has 𝐼𝐵 = 𝐼𝐴1 ∗ (𝑎^2 − 𝑎) and i understand that IA=-IB. Can anyone explain this part of the solution (just how this formula was determined)?
  15. I think i remember reading somewhere that most of the terminal equipment is rated at 75C, so 75 C is chosen as its more common? I'm not completly sure on that, just wanted to provide some input
  16. How critical is the version? Do you think a 2004 version would work?
  17. Does anyone have a good quick reference that details capability curves?
  18. So this is a phase to phase fault question. I thought that IA = 0 in phase to phase faults?
  19. @roy167 yep thats it, thanks for the explanation.
  20. Can anyone help me with the below question, it seems like such an easy concept but i can't quite wrap my mind around this one.
  21. I just went through the question and got the same answer.
  22. I believe you are right, my notes seem to agree with you. I couldn't find that problem in graffeo but i did find the below one. This looks correct.
