Veteran XV
I hooked up a transformer with a 600 delta primary, 480Y secondary. I thought that it was delta-delta so I left off the x0. I read around 236V (line to ground) on x1, x2, and x3. Once I realized and grounded the x0, I properly read 277.
Can you explain to me, with diagrams if possible, why connecting the center point gave me my extra 40 or so volts?
