Today, I set myself up with a three phase, 45 kVA, step up transformer, converting my 240v to 480v. My building is 240v three phase and I need 460 volts to test various 460v equipment.
This transformer really is a step down transformer, that I hooked up backwards. The "high side" is delta connected, and I do not see any way to change that.
Picture is here:

The transformer seems to be working fine, however, I have a grounding question. Given that this is 460v delta, what, if anything, should I connect to ground? Would it be proper to ground one of the legs of the 460v three phase secondary, to ground?
Thanks
