I already have a 25HP RPC produces 240V and 440V that I use for my CNC lathe and VMC, but I'd like to avoid having to spin it up just to run smaller machines.
I have some VFDs that take 380V-500V input, 1ph or 3ph.
So, I'd like to step up my household 240V 1ph to 480V 1ph.
Single phase transformers seem to be more costly than 3 phase transformer on a $/KVA basis, so I was thinking of getting a 3ph transformer to use to transform single phase power.
I'm thinking a delta LV/delta HV transformer would be best, but would like to see arguments/discussion on this.
I've already done some ogling on the Internet and most of the results are not pertinent and talk about doing 1ph->3ph, RPCs, ...
I want: 1ph 240V -> (3 ph transformer) -> 1ph 480V
1 bajillion KVA, but I'll settle for 10+ KVA
