1. ## CALIFORNIA IS OUT !!!!

Passed! PE Power, 1st time taker!
2. ## April 2018 Power PE Difficultly Level

I totally agree! The sample exam needs to be updated :|
3. ## 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.
4. ## April 2018 Power PE Difficultly Level

what's everyone doing to take their mind off the waiting game?
5. ## April 2018 Power PE Difficultly Level

Thank you for the encouraging words!
6. ## 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 it was pretty useless for the exam.
7. ## 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?
8. ## Shield Wires/Transmission lines

Hello, Cans someone tell me a good place to study shield wires and reactors from?
9. ## 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.
10. ## 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?

12. ## 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? Therefore the answer would be : (sqrt(2) * RMS voltage) / 2 = 85V? Is this right?
