I'd say your transformer is bad or somehow connected wrong.
** No way.
The OP's data shows it is operating normally and correctly.
10 degrees temp rise and a PF of 0.15 is A-OK.

Why doesn't the transformer data sheet include idle current, power
factor, etc.? Or is it embedded in some transformer standard I have to
spend 2000 swiss francs to get?
If it is covered under a IEEE standard it would be about uS$100 to $200.
I have several of them already, but maybe not the one for your
transformer. Nor is the IEEE standard a mandatory one, check local
regulation for what is mandatory.
Speaking of, i need to go buy some more standards right now.
