Voltage on a transformer

[hillbilly1]

I know that.

I was commenting about you saying it was still connected on the ground end. I assumed you meant the resistor (or what is left of it) is still connected on the ground end. But that wouldn't explain OPer's reading's. There still has to be a bolted fault somewhere down the line.

What I was saying was the fault may have taken out the resistor, which would make the common tie point float (or ungrounded as you were saying) with the faulted phase still going to ground. This would give the voltages the op is seeing.

That is correct. A few different words saying the same thing
