  1. Spent dang near $100 to frame mine. Still awaiting the certificate. But hey, I'll take this wait over the one endured from about 4:00PM Oct. 28, 2016 till 7:57AM Dec. 9, 2016.
  2. Any word on when certificates will be delivered? Glad you finally received your license.
  3. Sparky- I moved to the panhandle of FL in early Jan. and I received my license/pocket card almost two weeks ago. Even stranger, I received the packet, mentioned above by others, about a week or so after I received the license. I would think you should've gotten yours by now...? Has Ms. Wanda given you any indication as to what the delay is? The license is what matters, but I'm looking forward to the certificate; however, I've heard it takes 2-3 months after you become active to receive it if you do not attend the NSPE/TSPE banquet. Good luck and hopefully it comes soon! -TNPE
  4. You may be right. I'm just so used to processes like this taking much longer than they should, at least superficially. I will say the TN State Board has been pleasant to work with and they do expedite better in relation to how other Boards appear to operate.
  5. Units would be wrong; however, with that said, the only time P=S=VI is at unity power factor. Much like Q=S=VI at 90 degrees, which is a purely reactive load. Though these quantities are the same at these given conditions, the units are not the same. 100W is not the same as 100VA, just as 100VARs is not the same as 100VA. From a quantifiable standpoint, they are the same, but from a specific, theoretical view, they aren't. I had a much more detailed response written earlier today, but my computer had other ideas and wet the bed. If you have any other questions, let 'em rip! That's what this board is for, other than the occasional troll-fest, cause I had to crawl my ass under the bridge a time or four to troll during this grueling wait!! Best of luck going forward and kick this test's ass in the spring!
  6. I would guess ~30 days
  7. I, too, work for a three-lettered power company, but not the one you do.
  8. P=VIcos(theta) (real power...i.e. usable power delivered to a load) *Note: theta is the power factor angle, also inherently known as the angle between voltage and current, in which the current leads or lags the voltage, or even the impedance angle S=VI (apparent power) S=P+jQ (complex power...also, S=VI*) Q=VIsin(theta) (reactive power) If you understand these equations and the relationships between them all, coupled with a thorough understanding of how these are applied and used for 3-phase and single phase applications, you should be good. Not to sound blunt, but this should be the gimme stuff on the exam, if you're asked about it at all.
  9. No, Mrs. Phillips in Nashville said they were mailed Monday. USPS must be dragging their blankey, and their feet, cause it's Christmas... My brother mailed a package from Jackson last Friday and I didn't receive it until yesterday. Carrier pigeons or the pony express would be more expeditious. Guaranteed!!
  10. I gathered that tone from most posting here. I thought it was a very fair test, tricky, but fair. Nothing like I expected, at least with how the questions were framed. With that said, it tested your ability to apply concepts ad nauseam.
  11. I would guess @TWJ PE is saying he works in power system reliability (which encompasses performance, coordination, relay settings, loading and so forth....reliability is a mixed bag), not reliability in the sense of failure rates etc. that you would encounter in manufacturing processes. Quite rewarding and even impressive that you passed the Power PE as a Structural. Congrats!
  12. Symmetrical only relates to 3-phase faults (bolted or to ground - which really isn't a fault to ground). No other fault will be symmetrical. Period. Hence, Fortescue developed the technique of symmetrical components to accurately analyze asymmetrical faults (LG, 2LG, LL). As for your other questions pertaining to the DC component, I don't have much I can provide. I would say most breakers/controllers don't need any info on the DC comp., nor do they measure for it. Depending on the relay and application, MPU, instantaneous trip and other parameters are physically set by completing a coordination analysis to develop TCC curves (of course, depending on the relay, but could be using differentials, distance, etc.).
  13. Congrats @REsonance503! Good to know we weren't alone.
  14. Chemical Engineer? All the alchemy is making my head spin... No, wait, that's the booze!!!
  15. To be honest, I don't know that what I learned in college would have been of much help for the "theory" heavy topics. I picked up on the "theory" by picking up books, articles, anything I could get my hands on, and reading until I was blue in the face!!
