Out of curiosity, I took out my Tenma 72-545 1.5A isolation transformer.

On my Kill A Watt, it draws 60 mA unloaded, 3W / 7VA, with a power factor of
0.48.

I assume the current without a load varies with the primary inductance, not
the rated capacity. So the 2.45A drawn by the OP's transformer seems to be
unnaturally high.
