This problem can also be solved using the per-unit method. When using the per-unit method there is an impedance associated with the fault duty. This obtained first by getting the per-unit apparent power which is found by using the 1000kVA rating of the transformer the system's base apparent...

KDuff, The reason that they used 1/.09, is because that is the per-unit value of the current. The term 1 is the per-unit voltage because it is assumed that the bus voltage and the base voltage are the same and since V(per-unit) = V(actual) / V(base) =1 p.u.. That is how 1 came about. and...

Kduff70, It is true that you need to focus on concentrating on understanding the principles and concepts of each topic. I believe the best way to achive this is that when you are solving problems or answering question is to try to identify those key principles and concepts used to solve the...

It was May 22, 2014, I was away from the office training. During a break I checked my email after everyone returned to class as had been doing for a few days prior. I logged in and not expecting to see anything, but to a plesent suprise I saw the word Passed and my heart started to beat so fast...

I thank God that He blessed me to pass both the FE and PE exams before they were converted to CBTs. I don't care if I had to wait before I got my results. There is nothing like the printed word in front of you.

That would suck if they made the PE exam a CBT exam. Be careful of what you wish for., you just may get.

The best way to prepare for the FE and PE exams is to study the topics listed by NCEES until you understand the fundamental concepts, principles and practices pertaining to those topics listed. Then solve problems in the NCEES books as well as basic problems in some text books and other sources...

I hope that you all passed this round, and always try to remember that it is not if you pass the PE, but when you pass it. So never give up, after you pass, you will definitely become better engineers even though some of you may already be good engineers. May God bless you all.

Saif, a person should never give up on anything. Just because something is difficult and requires time does not mean that it is not meant for a person. Some people may require five attempts before passing, but that experience may make them become an expert as well as build character.

zm83, I used the same references that you used when I took the PE last year this time. I felt the same way about all of the references that you mentioned except Pansini, I did not have his book. I had James Burke's book Power Distribution Engineering, which was helpful during the exam and very...

I felt last year like you all feel currently, the only thing that I could remember about the exam were the 8-9 problems that I was certain that I missed and the more days passed by the more I felt that I would have to re-take the exam. However, when the results were released, I passed and then I...

Camara's reference guide is good, but his practice exams are useless. Also you have to keep in mind that there is no one self contained reference book out there that has every thing you need for that exam. That is why you have several reference items. Try to make sure that you understand the...

I would assume that because this is a timed exam and you only have six minutes per problem, I cannot see there being any involved calculus problems such as having to integrate an indefinite integral using integration techniques such as partial fractions expansion coulped with trigonometric...

rncole, That is pretty cool that you all's certificate looks like a real and perminate certificate, unlike my state and a few others, which issue temporary paper copy certificates.

The different NEC editions are for the most part arranged in the same order. However there may be some additions to some existing rules or standards or slight changes in conductor ratings. Although if you know how to nogotiate your way around the 2011 NEC edition you should be able to do the...

Kduff, You may want to add Glover and Sarma as a reference. He has really good information on faults (balanced & unbalanced) and system protection. He also has really good examples for many of the topics that you have been going over in Grainger. In my opinion the Glover and Sarma text is...

Hadi Sadaat's textbook has a really good explanation and example problems on auto-transformers as well. However Stephen Chapman is good for learning this topic.
