Hello all, I have a quick question, We recently had a bird perch on a single phase overhead utility pole break leaving a piece of the perch leaning towards one of the wires on the pole.  I believe this will cause a ground fault, but my manager does not agree.  Well he wasn't there and we fixed...

Chipol9, Hey man, don't get down and discouraged, you can pass.  It took me 3 times as well.  The one single advice that I can give and that helped me was this.  I understand that they sample exam is not the same or the problems are not the same, but NCEES will stick to the same topics...

oh sorry  AK- passed

Just found out I PASSED! so sweet!  

W9TWJ Thanks, now I remember, I appreciate the help. do you know why the first equation has + sin and the last two use - sin?

Attached is a picture of the problem.  I understand this problem and how using the first equation from above will give you the correct answer per NCEES, however in another sample exam, CI V2 problem 10 has a voltage drop for a single phase system, and they used the second equation above, and...

Hello all, It is getting down to brass tax, and I have been reviewing material for days now.  I have a question about voltage drop.  in the NCEES sample exam, problem 136, the solution states that the APPROXIMATE Vd=I (X sin theta + R cos theta).  I also seen a Voltage drop equation being Vd =...

Hello all, I have a questions about when you use the angle or 30 degree shift on changing between line and phase voltage on 3 phase ac problems. From what I understand you would use the 30 degree shift if the problem states that the voltage is either source or load voltage, if the problem...

Hello all, I was unsuccessful in the Oct 2012 exam. Felt ok about the test, was different from all the practice exams. I am hoping that my fellow engineers can let me know how close I was to passing and maybe ad some study tips. My score was 48/80, I really struggled on the Transmission and...

Where can I find this book on sale? Any ideas

I got it, from changing j.9 to polar, Sorry need to slow down and think Best of luck to all

In the NCEES solution it state the following: Ei=1-.9x1.05 at an angle of (90-18.19) My question is where did the 90 degrees come from? Thanks for the help

Thanks for all the help. Good luck to everyone on Friday.

Why do they not use 2 time R+jX because where the terminals Vab are you would have the impedance of b as well. Any help would be appreciated Thanks

knd107, I would be willing to purchase your: PE Electrical and Computer: Power Sample Questions and Solutions and Power Practice Problems for the Electrical and Computer PE I already have the last one, also I have the Power reference manual, I noticed that there are two reference manuals...
