Howdy all. I have a Gorton mill I'm trying to power. It has a 440V-only spindle motor, as well as a down-feed motor, cross-feed motor and coolant pump motor. It has all the original electrical panel and power supply hookup with fuses. I'm running my 220V shop supply to a Phase Craft RPC control box which starts (and channels the three phase power from) a 1725 rpm 5hp motor. The three phase generated measures about 256V from L1 to L2, L2 to L3 and L3 to L1. I run this through a fused disconnect box (Cutler Hammer, I believe), then on to the X1, X2 and X3 of a Square D transformer (model 6T5F).
This is a link to a little schematic.

According to what I'm looking at, H2, H4, and H5 used as outputs should give me 456V. Measuring in the same manner as I used for my 230V lines, I'm getting 256V, 256V and about 500V. Is there something I'm missing, or is this transformer shot?
Thanks for any help you might be.....I'm pretty new to this electrical stuff.
