The question asks: "During an open circuit test for a transformer?"
a) The high side has rated voltage applied, b) The high side is open, c) The low side is shorted, d) Both a & c, e) None of the above.
They have b as the answer, but this seems totally wrong. It should be a?
I bought the 2017 NEC Handbook, thinking it was over that, but apparently it is the 2014 being used on the exam.
I do have a 2014 version (code book, not handbook) as well, but unfortunately I had all of my page references on a lookup sheet for the 2017. Luckily the code references are also...
I'm just wondering, why does this problem have the wye phase impedances different from the node denotation? Ex: Node A has Zc, B Za, C Zb. Why not just denote them A Za, B Zb, C Zc?
Also, are the equations in the solution correct?
Thanks.
I am looking at page 16-17, where it has the phase currents Ia, Ib, Ic for delta connection. It says the line currents lag the phase currents by 30 deg on pg 16, but the equations on pg 17 look like the line currents are leading the phase currents by 30 deg. It has for example Ia = Iab * sqrt3 *...
Hi All,
I see some differences between the GA Tech equivalent circuit for an induction motor vs the EE Guide to Passing the PE. The GA Tech has the stator impedance between the input and core impedance, whereas the EE Guide has the stator impdance on the other side. I'm looking at pages 7-RM-34...
HI all,
I'm just wondering if it is ok to bring the NEC reference cards on the exam? I see that NFPA sells 13 cards, and, Amazon has what looks like a single 8.5x11 laminated card ("2017 National Electrical Code NEC Quick-Card by Builders Book Inc"). I'm just not sure if these are loose sheets...
I am looking to take the PE (Power) Exam in October and am looking for online review course recommendations. I'm leaning toward doing a live online course since it would most effectively get me into a routine since I would want to be in attendance at a set time each week. But I know one drawback...
Hi All,
I am planning to take the PE Electrical Exam (Power) in October of this year. I am wondering, what are the best exam materials out there that I should get? I'm thinking specifically about books, handouts, etc that I should have with me during the exam. I would like to make sure I have...
