Wow, I looked at the first schematic and the text is really bad!! Got to do some serious changing around in
AutoCAD for these and others!!

Anyhow, even though the text is only possible for ants to read, maybe we can discuss the schematics still.

This drawing is a detail of how a Delta would be connected as it's shown in the more familiar Triangle type
pictorial - reflected towards a normal line drawing.
It also demonstrates how a 120/240 volt 4 wire closed delta would be made up using 3 separate single phase
transformers [typical pole mounted bank].

Here's an open delta Vee connection for 3 phase 4 wire delta systems. It's similar to the closed delta, just
lacking one transformer.

These drawings show the two types of open delta connections - "Vee" connection and "Tee" connection, with
corresponding icon above.
