You can download the PDF of the presentation attached below. Audio of the presentation can be downloaded from here (http://pps2.com/yg/media/Power_System_Rules_of_Thumb.mp3).
You can also download a later version of this presentation (YG_Houston_2016_power_sys_analysis.pdf) that contains some different information, but doesn't exactly track the audio file. I'll be uploading the audio for this newer presentation at a later time.
Here's an updated version of this presentation.
An even later, more up-to-date version of the same presentation. I've included a video of me giving this particular version of the presentation to a class.

(Note: the system recording my lapel microphone switched off at about the 1 hour mark, so the remaining audio comes from the recording captured from a separate room mic)
(Note 2: There was a typo on slide 11 where it was supposed to say 86957 kVA, but instead said 86957 MVA!. Corrected in this latest version)
Here's another update on this same material...
