Better luck next time Elastic. You have the right attitude. Have a drink and dust yourself off ready for the next round! :)

Creber - rofl.

Nevermind. CAPLS answered my question in earlier post: "License Lookup should be updated by Monday morning.". Thanks CAPLS!!! I can enjoy my weekend now. Was freaking me out that my name wasn't showing up.

If we passed how long before the dept. consumer affairs website is updated?

PASSED ELECTRICAL!!!

I really thought today was going to be the day...but looks like we're about to burn through another day given the time :(

Exam results/diagnostics not yet available. Look familiar?

Who else has an employer that keeps asking: "Have you got your results yet??" -- So frustrating not being able to specify when to stop them from asking!!

Yes, good luck to everyone! Thanks to all the contributors on this board. I'm now thinking more about the after test beverages then the exam itself :P

NCEES method works for me on both problems. Show us your working....

My understanding is if the system is UNGROUNDED then the neutral will shift if phase B is connected to ground, which is why the line to line voltage is unchanged. However, if we the system is GROUNDED at the source then you are tying ground to neutral i.e. the neutral is tied to 0V. So Vcb =...

I *think* Vbg would then be equal to the line to neutral voltage because the system would be grounded.

Agreed

Soma, In a 3 phase system, line to neutral voltages are always phase shifted by 30 degrees behind line to line voltages. The only reason they convert to Y configuration is because it's convienant. You could work with the phase to phase voltages but then you need to apply Kirchhoff's voltage...

Soma, The load is delta connected so when you convert to Y (line to ground) the voltage will lag by 30 deg since the reference voltage is 0 deg. You will see this if you draw the phasor diagram. NCEES method is correct. Dean

I don't know what to expect on Friday....I've treated the practice exams as a guide as to the subject material to focus on. No doubt the questions will be more difficult, otherwise the failure rate wouldn't be as high as it is. We'll see ;)

Soma, Q510: 430.32© is not applicable since the selected overload device using 430.32(a)(1) is capable of carrying the load current. The overload device will be shunted during startup, so it won't affect startup of the motor.

Since the motor load is nonlinear, the phase current waveform will not be sinusoidal. So you can quickly discount B. For one cycle, diodes connected to Phase A will only conduct between 0 and 60 degs (+ve) and 120-240deg (-ve). As the circuit is not filtered by an inductor, the distortion...

I disagree. I think CI screwed this question up. If the turns ratio of common:series is 5:2, that means N1/N2=7/5=1.4. This is NOT a 230kV to 200kV step down xfmr but rather a 230/164kV step down autotransformer. Once you recognize this, you can apply the same method as NCEES, which is quicker...
