OK, but if...Trained investigators know that eye witness accounts are often mistaken.
"...the mere fault of being human results in distorted memory ..."
...his system has a high leg transformer which is corner grounded at A or C instead of at the center tap between A and C...
...and if his measurement of the B phase was to ground instead of the center tap...
...and if his measurements of A and C were to the center tap...
...wouldn't he get the numbers he has stated?
EDIT: Here's a question: Is a high leg 240 transformer ever intentionally left ungrounded? If so, what if that's what he has plus a ground fault on A or C? He didn't answer my question of what the voltages to ground were at A, B, C, and "N"; that would tell a tale.
