(OP)
I have researched several configurations used to provide three-phase 240 and 120/240 single phase. Some are V; High leg;and Scott T. It appears that I have the Scott T. However I am not sure since the distribution company stated that they are providing the service with a Delta Y set up.I am enclosing part of the analysis, and photos of the Tranformers setup.

The T connection still still in use is neither Scott nor Fortescque.
It is mostly seen in three phase to three phase dry type lighting transformers at around 37 KVA.

The readings are Black to ground 120;blue to groung 120 and orange to ground 120.
When the small transformer primary power is interrupted the voltage readings are black to ground 120; blue to ground 120 and orange to ground 106. The power between black to blue is 240 and 0volts between black to orange and orange to blue.
I have not measured any 208v from ground to neutral.
If there is a 208v how and where do I get a measurement?
