I have pdf of CI-4 sets(320Questions) @ 50;                         NCEES (80Q)- @30                         PPI Two sets(160Questions)@60;                          Graffeo (80Q) @40                         Kaplan (80Q) @40 I also have pdf of NESC, Wildi, Chapman, Beaty, Grainger, Glover, Sleva...

This may help you.

Is there any relation between pu and X/R ratio. From the info given in problem, can someone find pu Z of Gen. Any material on this part of the subject? Thanks

What is the probability of a question on Ampacity of conductors mixed with temperatures of terminations  Article 110.14. Just wanted to avoid to learn the ifs and buts written there. If it really matters, can someone give a simple language version of Art 110 applicability.

Q- If Xmer core were made from wood having same ratings as an iron cored. 1. Not possible technically 2. The  Xmer size will be very large compared to that of Iron cored 3. The size will be same as that of Iron core 4. Size will be smaller than Iron cored. Give your answers with reasoning

I think the answer to this question is wrong by CI. What do you say?

Can some one attempt this. I feel it is only MVA which changes  and not the Voltage to find new pu value; in such questions. WE discussed such question in another thread. 

Is question 12-9 on page 261 of Wildi has wrong answer wrt angle of line voltage V12

This question I found in Chapman. I think the question is wrong? It should be -Line Voltage on Primary side lags the Line Voltages of Secondary? As comments?

I never had an issue with turns ratio of a Xmer but while preparing for PE. I have been conventionally considering it same as voltage (Line/Phase) ratio whether in star star; delta delta or star delta  What should one answer for turns ratio when you face such a question in PE in star delta...

Some of the questions in PPI practice test are really smart and good. Does anyone else has similar feeling?

I am writing PE October exam. I stay 26 Miles form Pomona at Orange county. Will it be advisable to go on 26th evening and stay night at Pomona or go to Pomona in the morning of 27th Oct17. How about parking facility there? My wife will accompany me. If I go on 26th,  I find three choices-...

I saw that the forum resources provide us with 750kb of space to upload the diagrams etc. Once that is full the option of uploading pics disappears. You can delete the old stuff  and make space by visiting, Profile, then Attachments link there. May be it is useful for some.

Mine is a case of FE waiver. Anyone else here in similar boat? just to touch base for happenings in the process? If yes please PM me.

Can someone throw light on what is the depth of Engineering economy problems in PE. In NCEES-2011 question set,  there is no problem on this. Is it similar to FE exam?

I have calculated RMS values of a saw tooth waveform in two ways. 1. One is taking  take square of whole wave, integrate and take mean and then root of it. 2. Two split the wave into two parts; one DC and the AC parts. Take RMS of both separately. Then sqrt the squares of both. Theoretically...

What is the internal generated phase voltage in a 3 phase Synchronous generator. Given base values 250 KV, 100 MVA and Xd= 1.1 pu,  steady state current =.97 pu

Two single phase 10 HP, 500V motors connected to a single branch. What is the  minimum size of  90 deg, THHW  conductor used if one motor is continuous and the other is intermittent duty cycle. My problem is where to look for the fl current of a 10 hp 500v 1 ph motor. The table 430.248 does not...

I have an issue solving this problem. 1. Does the firing angle below 30 degrees matter in 3 Phase rectification. 2. How do we know which type of connection is this. 3 diode, 6 diode between L-L or 6 diodes center tap  with star connection.

Is the circuit in attached file is Full wave rectifier. Something wrong somewhere?
