This is an extension of Eric Dollard’s 2020 Energy Science & Technology Conference presentation, Method Of Symmetrical Co-Ordinates Applied To The Solution Of Polyphase Networks – A Sequel To The Work Of Charles Fortescue Of The Same Title. That presentation is now being applied to the analysis of Delta to Wye and Wye to Delta transformations in 3-Phase power systems. The representations that are commonly taught in engineering curriculum will be found to be in error. Also, to be presented will be the undesirability of the Wye connected power system, which is finding wide-spread use. For reference, see the paper The Electrical Utility In A Digital Age – Engineering Report NVE-1
Includes a PDF of the 211 slide PowerPoint presentation for reference.
