rg1 I appreciate your help but I stuck at right after  you do the voltage drop  I don't see where you  have 300/(.8Vr)*.5<(-36.86+53.13)  I don't see how you come up with 187.5/Vr<16.27= 180/Vr+j52,5/Vr

Thank you Rg1 I'm still confused perhaps if I can see the steps I would probably get it

Hi, can anybody help me figure  out this short transmission line problem.  I've attach the problem but I don't understand how the equation was able to solve for Vr can some please held me understand how Vr was calculated? thank you for any help on this problem Kduff70

thank I have them and they are helpful I was hoping for some examples

Does anybody know of any good example problem to study for the power exam. Outside of the usually Spin, Complex Imaginary, How the Pass the engineer test problem, Kaplan, Camara and Ncees ?

thank you

im down too

FeederFault, Thank you for clearing the equation part up for me. So the 35,555Amps is what all 8 circuit break would see therfore exceeding the 5000Amps Interrupting capacity. The reactors would not provide enough protection?

I was going through Graffeo ex .26 on page 57-58 I don’t quit understand the equation he uses to solve for the fault current why is it 1 over the impedance? And is the 35,555A the current over the eight circuit break. And will it be 4444 A across each of the circuit breaker. I have attached the...

thank you trainrider

In my pursuit to pass this test I've been trying to figure out a better way of studying. I know now that just studying the problem in spin,CI, NCEES and Graffeo are not enough. When I took the test in the spring I knew the topic well and was not surprised but more so stuck when certain...

Yes I think Nec Drill helps and the tom henry I did ok on that section of the exam i guess that one postive thing

Kovz and Ken Thank you, You just gave me some good insight I'm a working problem type person, but I think I have to do more of the how you can get this answer and breakdown every possible way you can work the problem by using the principle that apply to the problem. The thing that get me is I...

I'm trying to figure a better more precise way to study again for this test I do feel I need to try study principle and not so much the exam problems .I not sure if I should take another review course I heard some people talk about the GA Tech but I'm not sure if it will help with better...

thank you all

Thank You Poosri that helps I will definitely take your adivce I think stronger principle verse problem solve might be the way to go

Thank you June first I will start this journey again

I didn’t pass again, but I'm not giving up. The thing that get me is all the stuff that I was weak on the last test I did very well in but the stuff I did well on the last I did poor. I think I have to study principle more this next time while continuing to work all the spin, graffeo, CI , Ncees...
