    April 2018 Power PE Difficultly Level

    Exactly my thoughts. Just hoping the curve is in our favor. Also, if the exam is going to be this hard, I think NCEES should elevate the difficulty level on their sample exam too.

    April 2018 Power PE Difficultly Level

    I agree. The exam was much harder than the practice exam and some of the questions were topics I had never seen before. I feel like I guessed on many of them. The morning session was terrible and the afternoon was better. I am just hoping for the best at this point.I have a master's degree and...

    NCEES 510

    I am a bit perplexed with teh answer for 510. I solve this by taking teh FLA which is 65A and multiply that value by 1.15. I get 74.75. I choose 80A as the answer but that is wrong. Where in the NCEES does it say we need to size down?

    NCEES #113, 519 Power Electronic Questions

    What if the question stated two fuses were blown out on this problem? What would be the resulting waveform then? I am just curious.

    Output voltage of a full wave rectifier with an open diode

    Thank you for the replies! Diverting to another topic, can you tell me some good sources for reactors? I checked the Wildi Electrical Machines, drives and power systems and could not find it. Does anyone know if it's there in this book?

    Output voltage of a full wave rectifier with an open diode

    Thank you for the reply! Do you think it is worth buying the Engproguide? I am debating on it. I heard it's a downloadable link ?

    Output voltage of a full wave rectifier with an open diode

    Supposed we are given a full wave rectifier with an RMS input voltage of 120V , what would be the output voltage across the load if one of the diodes were open circuited? I think the rectifier would then operate as a half wave rectifier and the output voltage would be half of the peak voltage...

    Why do we not consider the negative sign for the In value in the final answer ?

    NEC question #109 Corner grounded delta load

    Hello, I came across this question on the NEC practice exam : A 3 phase 3 wire ungrounded 13.2 kV (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 the ground is most nearly : The answer is 13.2...

    NCEES 518

    Hello, I wanted to revisit this problem since I am a bit confused on the terms used. I calculated the load current in the generator as the full load current:  IGen=50MVA/(sqrt3*13.2kV)=2187 Amps and chose this answer which turns out is wrong. Why is this  answer not right?

    Voltage drop equation confusion

    @bobbilly I have the 2011 edition! I do not know what edition it is. I think your maybe right cause they corrected it?

    Voltage drop equation confusion

    Yes! Positive for leading load and negative for lagging load! Thank you!
