Hi Brian, Sure. References in the afternoon power session that I used were texts such as Power System Analysis by Grainger, IEEE books for industrial power distribution (there's a color system of books), a Machine theory book by Wildi, EERM of course, and a product catalog from manufacturers...

I took the PE October '07 (Power depth) and passed 1st try. Perhaps the grace of good luck was with me that day. But I felt the October test was fair, especially if you had the right references for the PM portion. I spent last January till October studying for it, with a few months in between...

Just like grownupsara, I also found out that I PASSED the Electrical PE-Power Depth on my first try (Illinois), so thank you to all members who helped answer my posted questions or gave me advice. I couldn't have made it if it wasn't for Engineer Boards, especially the Electrical Board...

Yes, indeed the results are posted online for Illinois. I PASSED! Good luck to others still waiting or haven't checked yet.

On a somewhat unrelated topic at hand, can someone give me last minute feedback on the most typical Articles/Tables/terminology seen on the PE exams for the NEC 2005? Here's what I have: Tabbed: Table 310.16 Ampacity Table 430.250 Motor FLC Chapter 9 Table 9 Art. 250 Grounding/Bonding...

shellbell500, If you're treating all those future costs from t=1 to 5 as future worths and you want to convert everything to present worth, shouldn't you be using the P/F factors instead? Just want to make sure John and you and anyone else reading this are on the same page... And John, the...

Just chiming in on what I'm doing. Reviewing some very good notes on Power PM that I took when I attended PE Review courses the past 3 months. I would say Thursday definitely do not go to work, take the day off, if you already hadn't done so, and do something easygoing or just relax in...

Great references guys. That electrical wheel with the third tier should definitely be published in some literature if it isn't already.

Sorry John, I wrote the values in the equation wrong. I didn't mean to confuse you, I just didn't proofread. Let me show you how I came up with the equations using 30 MVA on the line side. Line: Ibase = 30MVA/sqrt3*132kV = 131A Ipu = 75.92/131 = 0.58A Looking from the generator side now...

Ok just came back from making a visit out to the test site prior to this Friday's exam. I'm so glad I did because apparently the hotel name on the admission notice and the actual hotel name on the side of the expressway was not the same. It turns out that the former Best Western is now under...

OK I agree this transformer problem is a great example of utilizing per unit. So, I'm trying to analyze it the way shellbell has outlined above. But I can't seem to get the current his way. Can someone give me the two or three equations needed to set up the per unit base currents? I'm...

adc_PhDPE, Thanks for the advice. I went over the DC analysis like you mentioned and I think I have it down pat. I just don't see them asking a whole lot about load lines in the current exam format, except for if it's graphical and they ask you about a region of operation. But, I think...

John, I'll take a stab at this one. Hopefully it will boost my confidence if I am right. But I caution you to not take my explanation as correct until we have received the blessings of Luis, Jim, Benbo, etc. For NCEES 138, look at the equation you're setting up: V1=115kV V2=24kV V1/V2 =...

I noticed that EERM does not have a few of the more common op-amp circuits referenced in Figure 44.8 In particular, the following: - high-pass filter - band-pass filter - band-reject filter - differential amplifier You would think that they would at least include this in the Appendix, but...

Jim/Benbo, If I were to incorporate Benbo's explanation for the switch closing scenario into Jim's setup of equations, I would have the following (correct me if I'm wrong): switch open for long time prior to t=0: V_th = 6V(2K/(2K+1K) = 4V (thevenin = voltage divider) A+Be^(-t*tau)=v(0)...
