European two wire 230 to American three wire 240

[BAHLONGSHOT]

Hi, I have a machine I am sending to Turkey and it operates on standard American single phase 240 vac. The problem is the place its going in Turkey can only supply single phase 230 which is one single hot wire and a Neautral/ Ground wire. Is there a transformer or converter of some sort that I can add to my machine to achieve my goal?

Does the machine need a neutral? (ie line, line, neutral, ground)?

If the machine currently has only two hots and a ground it should work on Turkey's system provided the machine is ok with 50Hz.

Once again Turkeys system is a single phase single leg 230 vac. That's where the initial problem is starting.

Yes, but does your machine have a neutral wire?

I'm assuming that it needs split-phase because it has a neutral use (i.e. some loads are on the 120-0 configuration). It might need split phase if the insulation is not rated for 230V to earth, but that would be a little unusual.

Basically if you can live with 50Hz then the problem can be solved with a suitable transformer. It won't be that cheap for the 12kVA sort of figure mentioned earlier, but I would guess it is in the $3k region, so an order of magnitude cheaper then if you also want to do frequency conversion.

Ok, I appreciate everyone's input. I am listing my remedy, I found a 15 kva transformer that will convert their single wire 230 vac in Turkey to our normal American single phase 240. I attached the spec sheet for it.

Good to see you found something cheaper than my guess

It will probably need fed by a breaker that allows for the switch-on surge (e.g. C-curve or D-curve), that might be separate from any double-pole breaker on the output of the transformer that protects your equipment.

Also make very sure that someone checks the output voltages before they connect it to your equipment, just in case someone has screwed up with the transformer tap configuration...

that might be separate from any double-pole breaker on the output of the transformer that protects your equipment.

Remember that a 50A breaker on the input of the transformer will act like a 100A breaker on the output if your fault is phase to ground/neutral, instead of phase-phase.

voltage variations will be evident anyway
