Looking for remmendations for review material on Transmission and Distribution Protection. I do poorly in this section.

Can anyone recommend a good review for power electronics?  I continue to do poorly in this section.

Has anyone worked this problem yet? 34.5kv, 3phase, 4 wire, Y-connected, distrobution panel is experiencing unbalanced load conditions. Phase A load=(120+65j)kva @ (19.9 angle 0) kv. Phase C load=(65+20j)kva @ (19.9 angle 0)kv. Calculate the neutral current. for the life of me, I do not...

The new exam format is killing me. I have taken this thing some many times I have seen the exam 3 different ways. I have scored everywhere between 50-69% and have yet to pass the stupid thing. This last time, I thought was the easiest exam to date, guess not. (one of my lowest scores). I am...

I did poorly on the morning sections which was my down fall. Does anyone have any recommendations for reference material or pointers. Specifically, "Devices and Power Electronic Circuits" relays, plcs, variable speed dreives, power supplies, etc. and "Measurement and Instrumentation" VOM...

Has anyone used any of the classes on PDHonline.org for a review? I am looking at some of them and am curious if it is worth anything. thanks, cabby

Can someone point me to reference material on tripping schemes or something to aid in solving this. thanks, cabby

Has anyone worked this problem yet? I am not sure how they are getting 2 times the peak voltage? Does the capacitor charge to the same voltage as the 120Vrms source? Then do KVL which would give you 240Vrms. Or sqrt2 * 240Vrms=339Vpeak? I am not sure if this is the right approach or not...

Has anyone worked this yet? I do not remember symmetrical components. Anyone have a crash course? thanks, cabby

Does anyone know of a company that will rent a Fluke 1760TR? It is a pricey piece of equipment and I am just looking to use it for some testing on a project. thanks, cabby

Can anyone explain why they did not use the formula at the bottom of Table 9 since the PF given was .8 vice the table .85? thanks, cabby

I can come up with the 480v Base Isc of 1203A. However, I do not understand how they are obtaining the p.u. Isc? 1MVA is given, transformer has a 4% impedence, I assume that is the .04. But where are they getting the .025? thanks,

Can anyone explain the solution better than the answer section? I am just not getting it.

Is anyone familiar with the new reference material at the other "site". I see they now have an eighth edition. Does it account for the new exam formats? Is the reference book set up differently then previous ones? cabby

Squirrel cage motor, 40HP, 460V, 3 phase, 60hz, 52A, .87PF lagging. what is the maximum locked-rotor current for selection of the motor disconnect? Has any one worked this yet? I am using the formula in the NEC Handbook Section 430.7, however, I get 251A and the book's solution is 412A. What...

Has anyone purchased teh IEEE P.E. Review before? I purchased this about a year ago. Unfornutately, I just took the wrapper off the Machineery & Application Disks. To my dismay, the darn disks are BLANK! If anyone has had a problem with the IEEE Review Disks could you tell me who to...

This is out of Kaplan's Review, Prob 2.8. Can anyone shed some light? I keep going around in circles with this and never get the correct voltage regulation in the book. Would be nice to see in pu if anyone has it. Problem states to find the voltage regulation at .8 PF lagging...

I am reviewing for the PE exam and came across "ferroresonance" is anyone familiar with this. The statement in which it is being used is "the possibility of ferroresonance should be examined in distribution transformers with ungrounded primaries" If anyone is familiar with what it is, I could...

Can anyone out there explain the solution to prob 539 in the NCEES sample Exam Power Module? I do not understand the approach. I thought I had a fault on the secondary side of a transformer and I need to find the voltage on the primary side. I am sure I am viewing the problem wrong. If...

Is anyone working the Kaplan Review? I do not understand Prob 7.5, pg146. I do not understand how they constructed their Karnaugh map in the solution. thanks, cabby
