Correct - as Bjarney mentions I was refering to a 3Ø 4 Wire Delta - with Center Tapped winding, of the "Double Voltage" family.
I found 240 VAC on two of the three Phase Lines - as measured L-G, and on one Phase Line, found "More Than 240 VAC to Ground" - and since this smells "Delta-Ish", one could figure the Voltage to Ground on that single Maverick Phase Line to be in the area of 415.68 VAC
(240 × 1.732)
First thing I was thinking when there was a Voltage to Ground measured (with a Wiggy), was a Wye setup - having the Common Star Point Grounded. Finding >240 VAC to Ground on one Phase Line was totally unexpected, and debunked the Wye concept!
This was a nice "Whaddaheck" experience to me, as it was so totally unexpected!
(however, the guy I was working with found this to be of no interest, which really bummed me out!).
Bjarney;
The Image referenced in the last post didn't have "Image Tags" enclosing the URL (as far as I can see).
Let's see if it shows up in this message with tags surrounding it.
If it does not work, maybe you can try something else, enclosing its URL with image tags.
FYI, this looks like:
[img] URL to reference [/img]
Only, do not use any spaces like I have done here (did this to eliminate the BB software from going Berserk trying to figure out that tag!).
