    Protection Problems

    Sounds great. I have the School of PE notes, EngProGuides and Graffeo. I was definitely intending using these 3 for my primaries. Then if I'm getting too badly shot up I'll get backup from the others. I know EngProGuides and Graffeo and where to find stuff since I read through them. I gotta finish tabbing the School of PE notes. Sounds like a good plan.

    Protection Problems

    I would try to lighten up a bit on the resources. Just know the basic concepts. Protection can have a broad range: Relay pick up calculations. Reading fuse, circuit breaker curves. Types of relays and configurations. Fuse and circuit breaker properties. Theory problems based on NEC. I read through EngProGuides, Graffeo and another book called Fundamentals of Power System Protection by Y.G. Paithankar and S.R. Bhide. It's a great book, better than Blackburn's in my opinion. Easy to follow, worked out examples and calculations. It's also broken out into coherent sections. I regret buying the Blackburn book. I read it for a day, got lost and put it down.

    I guess "liquid sodium flow characteristics through a pipe" will be covered under the Electrical General Mechanics of Fluid Flow Through Wires scope of the exam. I think I got a reference on that!

    Oh, believe me, I'm expecting it and I know there's no much I could have done during studying. I'm sure a lot of these questions throw almost everyone off. I'm prepared to look things up and make educated guesses, unfortunately. I guess for this exam you basically study concepts and the rest is done during the exam with references.

    D-Day approaching

    Don't dread it but embrace it. Remember, the things we fear have already happened to us. Also, my favorite confidence song is Tool - Lateralus: I'm reaching up and reaching out. I'm reaching for the random or whatever will bewilder me. Whatever will bewilder me. And following our will and wind We may just go where no one's been. We'll ride the spiral to the end And may just go where no one's been. Spiral out. Keep going.

    So you're pumped too, huh? I just wanna take a whole bunch of caffeine, go all out and get it done. I hate having this burden hang over me. I'm more fascinated just seeing the exam itself since there's a whole lot of gossip about it. You're absolutely right. I'm trying to wind down a bit. If I didn't study a certain topic in these 6 months then I'm just going to refer to it in my references during the exam. There's only so much we can learn in a certain period of time.

    Complex Imaginary Module 1 Problem 1

    It's a trick question. They want to know the PEAK voltage not the DC voltage. You solved for the DC voltage. The peak voltage is what @BirdGrave has said. 125Vrms * root(2) = 177V. Careful when reading those problems.

    I took the last paper FE exam back in 2013 and those hours flew by. Even during the 4 hour LEED exam felt like an hour. It's all relative. Anyway, it's time to ditch that EIT for something better!

    Normally I am not optimistic but I have a decent feeling about this. Good printout. I already have it in my binder. 😬 We will be fine. In fact, I'm looking forward to it. It's going to be fun.

    NCEES Power Practice Exam #129

    Yep. Just another one of those little things to remember. Do it per phase with a reference angle of 0 and then multiply by root 3 to get the line voltage. Also, there is an additional formula for three-phase, short transmission lines to calculate the actual three phase voltage drop based on R and X values: Voltage drop (Line-to-Line) = (R*cos(theta)) + (X*sin(theta)) * I * root (3) R = Resistance of the line X = Reactance of the line

    Practice exam

    Sounds like a good approach. You definitely don't want to spend time looking up the smallest formula that can be easily remembered. My binder is setup the same way. Equations and index at the front, then the Eng Pro Guide study guide. The equations are from the EngProGuide cheat sheet and from Graffeo. I think it's a good compilation of equations. At the end of each section I have printouts of the recommended references given by EngProGuides. It's tabbed with numbers and colors according to section. I'm only only trying to use my references for the really insane questions. The basic stuff for each subject is pretty much memorized at this point.

    Practice exam

    The practice exams are supposed to provide you with an idea of the concepts and what to consider in a problem given. I guess we'll see on Friday if the concepts have stuck with me. Just got to know where to apply them. If you get stuck on a problem then just revert back to your references. To expedite the exam process, I have memorized some key equations and how they're applied to a problem. Kind of like muscle memory. I'm only going to use my references if I need to. Hopefully that works...

    NCEES Power Practice Exam #129

    R=0.049 X=j0.049 Z = (0.049+j0.048)(0.25 - distance factor) = 0.017<44.40 Vr = Vs-IZ -> (277> -30) - (400< -36.87)*(0.017< 44.40) = 271.63< -30.87 * (root 3) = 470.49< -30.87V = 470V Hope this helps.

    I'm thinking that they just selected the voltage to neutral phase angle to be 0 at random for simplification. In fact, it could be anything. You're right that it would be -30 degrees with a line-to-line reference voltage at 0 degrees. In the end the voltage angle is irrelevant as shown in the answers. Notice how in the solution they neglect the voltage angle when getting the phase to phase voltage. You would just need the correct angles for current and impedance to get the right voltage value.
