    If that was a 3 phase wye source, then wye line to line voltage would be about 193 V.

      It's 3 phase 120/208 but only single phase to the residence

        Is 116 a typo? Should be 216?
        Yes 216 sorry

          nickelec:

          Your measurements after correction do not correlate with a a center tapped single phase transformer with mostly resistive loading, and no major source series inductance.

          With whatever present loading is on my home I read 122.7, 122.0, and 244.7 . It is just luck that I didn't see a tenth or two difference in the sum. These measurements are with one meter, and power system voltage jumps around a little over short times.

            Calculated using law of cosines with the 118V and 105V phases at 120 degrees from eachother?

              But with the phase angle voltages don't add up with simple math like they do with true single phase 120/240 system.
              I live for today, I'm just a day behind.

                I used a different technique, but the result is the same.
