Delta Hight Leg Phasor

[bjenks]

Hi,

Awhile back I created a spreadsheet that showed how the current and voltage will change on a wye unbalanced system depending on single phase or three phase loads being added.

I have since tried doing the same thing with a delta high leg transformer. I can't find any real examples on the internet so I did it from scratch. I am asking for anyone to download the spreadsheet and look at sheet "Delta Load View" and see if you can check my logic. You enter loads only and not in any other voltage or current field. Thank you for your feedback. I am a little worried about how I treated the Vcn and Van phase relationships to the Vca and Vab.

Surely someone would look at this spreadsheet and comment back on the delta high leg phasor? Maybe people are worried about downloading stuff?
