    Post your PE Electical Exam results in here

    Passed in the state of Puerto Rico. First time taker, there wasn't a grade, just a pass/fail. Thank you to all the members of the board who helped; there were many, I particularly remember flyer_PE and knght1fox3 helping out a lot. Thanks agian.

    NCEES Website and Exam Results

    Hello, I have been trying to log inot my NCEES account to check my exam grade but I have been unable. I get a message that says "Your results are currently unavailable......" Is anyone else getting this message?

    Final days before the big test!

    Sparky07, How similar are the NCEES sample questions to the real deal. I've read from others in the forum that they very similar; since you seem to ahve taken it not to long ago, I was wondering if you could share your opinion. Thanks!

    NCEES #133

    I wasn't able to find the answer in the 2011 code either and I looked every where. I would think the question is now invalid, since it isn't addressed in the new NEC version.

    Grounding Rods

    Have not seen this problem, but here is an idea, not sure if this is correct: Call the rods R1, R2, and R3 (R for resistance). If they are all connected in parallel, once you add two of the resistances in parallel (say R3llR2), the equivalent resistance is in series with remaining resistance...

    MVA Method

    Its a method used to find faults. In my opinion is faster and uses less arithmetic than the per unit method; therefore, there is less room for mistakes. In addition, a one-line diagram can be transformed and reduced by using blocks (if you want to), so it is visual; I'm a visual person and...

    Phase Shifts in Transformers:

    I'm going to agree with DK PE on this one. My understanding is that the HIGH side will always lead the LOW side by 30 degree regardless of transformer configuration (delta - Y, or Y - delta). I'm sure this phase shift can be modified for particular applications, but unless otherwise stated in...

    Wye-connected ungrounded System

    This is yet another example where PPI questions are vague and leave too much space for assumptions. I think the test will not have questions where assumptions can be made. Had this question come from the NCEES sample book, it would have probably asked for the line voltage and it would have...

    Synchronous Generator PPI problem

    Something I've noticed about PPI questions is that sometimes they leave some things open to interpretation. The NCEES sample questions do not do this; in the NCEES questions there is no room for interpretation because they state everything you need to know about the problem at hand. Hopefully...

    OK! that one made the light bulb turn on. Thanks Flyer_PE!

    NCEES #540

    I apologize. On DK PE's quote of my previous message above I meant to say the MVA rating of the transformer. DK PE, your example does make sense. Where I get confused on this question is that the MVA rating of the transformer is accounted for in the computation even though the question asked...

    NCEES #540

    Flyer_PE, Thanks for the explanation, and thank you for helping not just me but every one else in this forum in passing the test. I hate to sound like an idiot but I'm still not getting it. I understand the transformer is not a contributor; a contributor is a motor or a generator. However...

    NCEES #540

    BH_Cubed, I have the same question. Why is the short circuit contribution from the transformer being considered, when the question clearly asks for the Generator contribution only. Flyer_PE tried to answer this question at the beginning of the thread but I still don't understand. Can anyone...

    Opinion on Substation/T-Line Engineer

    Hello, I'm looking to switch career paths from designing electrical systems for the healthcare industry to substation/transmission lines engineering. I was hoping I could get opinions from engineers who work with medium and high voltage. I want to know what you think the future of the...

    Relay Schemes

    A found white paper that goes over relay schemes. I thought it would be a good idea to share it with this forum. It may come in handy during the PE exam.Grounding and Ground Fault Protection of Multiple Generators.pdf Enjoy.

    NCEES #109 Power

    A 3-pahse, 3-wire, ungrounded, 13.2kV (phase-to-phase) wye-connected source is connected to a balanced delta load that is grounded on corner A. The voltage measured between corner B and ground is most nearly: The answer to the problem is 13.2kV. but what I want to know is, what would be the...

    Transient Study Question

    Flyer_PE, Thanks for the response. I now realize the stupidity of my question. If the tests are run at the machine ratings; the ratings are the machines base values. Since the per unit value is: Actual value/Base value Then the I, V, and S will all be 1. Thanks again.

    Transient Study Question

    I'm strugguling to understand why the current in this problem is I = 1pu. The problem is as follows: An electric generator is rated for 20MVA, 13.8KV. It is a diesel engine driven, three phase, four-wire system. The generator is sailent pole with dampers. The manufacturer's data for...

    Does anyone know of a short white paper that goes over the basics of SPDs and some of the schemes used? Thanks in advance
