When you are given a piece of equipment and told its actual paramaters are those paramaters always taken as 1 per unit for the respective voltage, VA, and current? For instance if we have a 10MVA generator, rated 13.8kV, 418A, is the rated voltage, current and VA equal to 1.0 where 1.0 pu...

When looking at example 1.1 in Power System Analysis by Grainger I notice that the give the Apparent power equation to be S=VI*. In example 1.1 they use the apparent power calculated for S1 to be S1=V(-I)*. I believe this is because I has a direction that is different from the source...

In the attached question and solution for problem #3 of the Kaplan morning power exam I dont understand why the solution states to use Q=(sqrt3)(Pb-Pa) to find the total reactive power. Now I understand that with a two wattmeter configuration reactive power Q=(sqrt3)(P1-P2) however I cant seem...

In the Kaplan sample afternoon exam problem #38 I understand the solution they give however I'm curios if thres another way to find thid solution. They used the Iab current dropped across the 10ohm resistor to determine the voltage dropped across the resistor and then use this voltage drop...

Can someone help me understand how they came up with the equivelent circuit in the attached figure 7-8(B) from Schaum's outline. I understand that it is a source trasformation problem but I cannot for the life of me figure out where they got the new impedance values from. I understand how they...

Does anyone have a copy of the Kaiser Exam that they would be willing to send me. I have seen previous threads where people have mentioned that they had this exam and solutions and were willing to send it through a PM. I'm trying to get all of the practice solving test problems that I can. If...

Does anyone know where I can find some good information (websites etc...) on power electronic circuits used for AC-DC conversion and in VFD's similar to those shown in the sample exams. I am looking to learn more specificlly on calculating the magnitudes of the ouput DC voltages, and the effect...

In NCEES power exam prblem 515 can someone please explain to me why you have to use 2x the peak voltage for determining the maximum reverse rating across the diode? I understand that you multiply the 120rms voltage by 1.4 to get a peak voltage of 170V but I dont understand why you must use 2x...

Has anyone here used PPI's Exam Cafe problems for studying for the electrical power exam. I was thinking about signing up for the 30-Day option to practice some additional problems in preperation for the power exam but wanted to hear if others found this beneficial?

Does anyone know where I can find sample power problems online for free? I have completed the NCEES practice exam and have ordered the Kaplan exam. I am looking for additional practice problems to practice as many as I can to get in the routine of solving these problems. Are there any on this...

I plan on taking the general exam for the afternoon session. Is there somewhere that lists that types of questions that will be covered on the general exam. For example if I am looking at my study manual are there certain types of questions in each topic area that wont be included in the general...
