I can only assume that the star (Y) system was a four wire system. The star
system can be either 3 or 4 wire it appears, whereas delta is always 3 wire.
It was 1970 when I did this , so if anyone wants to put me right -feel free.
It does seem a logical explanation though.

Most know
about motor rotation but he was talking about delta versus
Y. This can be quite different.
What _is_ the difference between delta and Y? A while ago we had a
discussion that ended up revolving around what point is grounded
("neutral"). As far as I can see, delta and Y are basically
equivalent, provided you don't try to refer anything to ground (or
anything else beyond the three phases), and provided you don't overload
anything.
Am I missing something?
