Take three (3) single phase transformers -- of identical manufacture -- and wire them up, yourself. Each single phase transformer would be wound 347 to 120 turns. The 347VAC secondary would have 120 turns; the 120VAC primary would have 347 turns; each times the number required to handle the kVA Short answer - no. 100-240v 50/60 hz is known as a universal power supply and lg oled tv's are 120v. which means to make it work in your country you would have to use a voltage converter. and you cannot use any voltage converter like a simple adapter, the voltage converter to convert from 120 to 220/230v would have to support the power consumption load of the oled tv, that is the converter 208V to 120V Isolation Transformer Converts High-Voltage Input to Low-Voltage Output. This 3kVA 3kW SmartOnline® isolation transformer converts your UPS, utility or generator's 208V high-voltage input to 120V low-voltage output. It features 12 NEMA 5-15/20R outlets for connecting equipment with common NEMA 5-15P and NEMA 5-20P plugs. Let N equal the number of turns around the transformer of each wire. The relationship between the voltage and the number of turns on each side is described by the equation: V_ {S}/V_ {P} = N_ {S}/N_ {P} V S/V P = N S/N P. This means that increasing the "outgoing" voltage is accomplished by increasing the number of turns, resulting in a step-up . I've two Vibro Graver electric engravers (120V 60Hz) with me. I gave one to a friend who recently moved to another country. He got a step down converter from 220V to 110V but then he noticed the frequency used there is 50Hz. What would the effects of using the device on a 110V 50Hz supply when the device is meant to be used on 120V 60Hz supply. Your idea of splitting 240V into two 120V half-circuits is called an MWBC and it's too difficult to do given current codes. But it's just as easy to wire two full circuits. (you couldn't have used existing /2 cable for an MWBC, so you'd have to pull a /3; well then pull a /2/2 (4+ground) or dual /2's and done. GoHz 120V 60Hz to 240V 50Hz Converter. You can use a GoHz single phase converter to change US power 120V 60Hz to your expected Hz and Volts. In your case, you need to find out the total loads' capacity of your machines, and the peak working amps during starting, then choose a corresponding frequency converter. 400 amps of 120 volt loads is 48000VA. balance that on 120/240 single phase source and it is 200 amps, balance it on three phase wye and it is only about 133 amps. If what you have is 400 amps after balancing across three phases then total VA is like 144000, which is over the100 kVA transformer you mentioned. In theory you could remove the 240 breaker, add a 120, wire the black wire to it, and wire the red to neutral, and you have an ungrounded 120 with the wrong color wires. But don't do that. If you're unsure about anything electrical, hire a licensed electrician to come look at it.
