  1. I used the last two weeks to tidy up any loose ends on topics I was weaker on. I didn't use a cheat sheet, rather I learned my materials while studying (developed comfortability) and let that be my "cheat sheet." There's not a template that is all-inclusive such that any person could follow it and pass. If there were, I'd gladly give it to you. You know your strengths and weaknesses. Bolster your strengths and mitigate your weaknesses. I cant stress enough how important it is to know your materials. Really, just as important if not more so than being a "student" of the subje
  2. Hard to have a defined system if everyone knew the problems, therefore, either diminishing the value of being a PE or being impossible to pass. Best I can give you is this, the test is almost identical in difficulty and style to the published practice exam.
  3. I have worked a lot of them at some point in my past, but I was speaking to presentation and overall layout of the book. I takes a fundamental, foundational approach.
  4. I, too, am 32. Took the exam at 31, though. I don't necessarily agree with rg1 with regards to Chapman. I think you can almost pass the test exclusively with his book, Graffeo, NEC and NESC. Now, I wouldn't show up with only those materials, but it is easily passable with them alone. I do not own a copy of Wildi, but I have made a cursory scan of it. IMHO, it is more of an "academic" book, but Chapman is better suited for this type of scenario (Chapman was actually a college text of mine). This exam is not about "academics" per se, rather it is more about fundamentals and knowing how to
  5. If you're talking about Stephen Chapman, then yes, it is an essential. I used it almost exclusively when I took the PE (also used Graffeo, NEC and NESC, where practical). I also used a few other college texts for specific problems, but used Chapman and Graffeo for at least 75-80% of the exam.
  6. No problem. The confusion with most of these scenarios is attributed directly to language. However, if you think of it intuitively, it makes perfect sense. As I've said before, the PE exam will ask you EXACTLY what they're looking for. There should be no confusion if you're well-versed (and from what I've seen, you are, and you should have no trouble). As far as it being legislated, I don't know that I would define it that way. Just know that a voltage ratio and XFMR winding ratio can be different, depending on winding configuration. Just remember, you will always be relating the ph
  7. The voltage ratio may be given in line quantities, but the turns ratio of the XFMR is always with regards to phase (e.g. phase for delta is LL and phase for wye is LN).
  8. Don't really have the energy at the moment to comb through "what" they did, but kW is NOT demand!!! The only time "demand" is equal to kW is at unity. This problem is not dealing with unity, so I'll have to come back to this later. Furthermore, highly unlikely you'd see a scenario this convoluted, with a demand and PF correction problem intricately interwoven in this manner. Once again, this test is heavy on concepts, not how well can you dissect what I said, and then proceed to solve with some method that is as convoluted as the problem statement. Dont know that I agree with what
  9. Unless otherwise told, you always hold kW constant when performing PF correction. Did you mean KVA or KVAR, because each changes with kW held constant? Likewise, all quantities change if kW is changed and you're adjusting PF with added reactance.
  10. I don't have that material, but a description or simply posting an img would be good. From there, I can try to help you in understanding ratings and analyses methods. I have always worked with KVAR, kW and KVA from the power triangle, unless other methods are necessary to solve the problem. Generally speaking, if it is a PF correction problem, it is simply a case of holding kW constant and analyzing from there. If it's a delta or wye situation, remember what happens with impedance and phase/line current.... power remains the same!!
  11. Demand/energy management and load factor are all somewhat similar; and essentially, you'll need to take into account the total available output in some timeframe, and relate it to what was actually used/consumed in that same timeframe (think of a 5-gallon bucket of water with 3-gallons in it - just as a comparison). Not an all-inclusive explanation, but should be good enough to get you started.
  12. -Read the first sentence after -Nope-... The opportunity around the time I took the PE is the job I accepted. This has been in the pipeline for a while, as most jobs worth even taking a look at are. -Last day at this job -What power? The power to not GAF cause I have another, much better opportunity. If you worked where I currently do and experienced the pompasity and hubris, you'd see exactly what I mean.
  13. Nope. Took the PE in Oct. 2016 and had an opportunity around the time I took the exam. Posthumously, for the exam anyway, I received an offer that slated me at $8,000 higher on annual salary, and this was before I received the passing notice. I have since accepted and anticipate growth beyond what I will ever gain in my current position. The arrogant, condescending tones from a select few (one?) at the top made this decision easy. Not to mention, the new position in the FL panhandle. A cursory view of my background: Substations, substations, substations, and anything related, up
