Today I dragged home a 27 kVA 3-phase dry-type transformer. It's old but I'm hoping still serviceable. Inside were 3 very dirty, fragile and waterstained pages stapled together which were the original build document from GS Hevi-Duty back in 1981. The wiring diagram is shown:
It looks like this unit could be rewired for wye or delta for several voltages. I have a 230V RPC set up and running. Can someone give me a recommendation as to how exactly to wire this transformer? I want to power a 460V machine with it.
Thanks!
