Power Systems Rules of Thumb

[Dave Loucks]

This presentation discusses:

• Transformer review (including deriving internal R and X from loss data)
• Fault calculations
• Per Unit theory and practice
• Asymmetric Faults
• X/R rules of thumb

You can download the PDF of the presentation attached below.  Audio of the presentation can be downloaded from here.

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)
