126 volts sounds very close to a standard home voltage of 120 volts, which is single phase. 208v is a three phase voltage, and is the lowest I have seen. 240 is single phase (usually center tapped, so in your house you have +120, and -120 referenced to the neutral which provides the normal 240 for dryers, stoves, etc.).

What is the difference between 277 volts and 240 volts?
These voltages are both wye connection three phase voltages. The voltage difference comes from the primary three phase voltage supplies. 277 volts is obtained from 277 x 1.73 = 480 and 240 volts is obtained from 240 x 1.73 = 415. 480/277 volts is a common three phase American voltage. 415/240 volts is a European voltage. In Canada a common three phase voltage is 347/600. The 240 volts could also be a single phase voltage in North America derived from a split phase secondary on a distribution transformer that supplies 120/240 volts to homes.
How do you convert 3 phase star configuration 380 volts supply into 220 volts supply?
The process of obtaining 220 volts from 380 volts is quite simple. 380 volts is a three phase four wire system voltage. The 220 volts is obtained by taking the sq. root of 3 which equals 1.73 and dividing it into the phase voltage. 380/1.73 = 220 volts. This holds true with any three phase four wire voltage system. 208/1.73 = 120 volts, 415/1.73 = 230 volts, 480/1.73 = 277 volts and 600/1.73 = 347 volts. This lower voltage is present on any of the three phase legs of the three phase system to the neutral which is grounded on a wye connection.
How do you calculate 440v phase?
Let's get the terminology correct. A 'phase voltage' is measured across a phase, whereas a line voltage is measured between two lines. So there is no such thing as a 'phase to phase' voltage -it's a line to line voltage (hence the term 'line voltage').
What is the most typical industrial three-phase voltage in Thailand?
The most typical three-phase voltage used in China is 380 V.
How do you get single phase 440 from three phase 440?
You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.
How will a 3 phase panel give you 110 volts and 220 volts?
A three phase panel will not give you 110 and 220 volts. A three phase four wire panel will, but not at these voltages. The nearest voltages will be 120 and 208 volts. The 120 volt is the wye voltage of 208 volts. 208/1.73 = 120 volts. A single phase three wire panel will give you 110 and 220 volts.

Why 380 volts line to line if connect line to neutral is 220 volts?
A voltage of 380 volts is a three phase voltage. On a three phase four wire system, each phase leg to neutral (grounded) will give you 220 volts. This voltage is obtained by dividing the phase voltage by 1.73, as the phase legs are generated 120 degrees from each other. Square root of three is 1.73 divided into 380 equals 220 volts.
What is the most typical industrial three-phase voltage in Thailand?
The most typical three-phase voltage used in China is 380 V.
How many volt each phase in three phase?
In a balanced three-phase system, each phase is typically 120 volts. This means that the line-to-line voltage between any two phases is 208 volts.

Is 380 volts electric motor a single phase or 3 Phase?
It is probably a three phase 50 Hz motor.
How do you obtain a 230 volts single phase supply from a 400 volts three phase four wire supply?
You can use a transformer to step down the voltage from 400 volts three phase to 230 volts single phase. Connect one of the phases and the neutral of the three phase supply to the transformer primary winding and then connect the secondary winding to get the desired 230 volts single phase supply.
What is the voltage of a 3 phase 4 wire 277 volt lighting circuit?
The voltage of 277 volts is the wye of a three phase 480 volt system. Just as the voltage of 347 is the wye voltage of a three phase 600 volt system. To obtain these voltages for any three phase system, take the three phase voltage and divide it by 1.73. 480/1.73 = 277 volts, 600/1.73 = 347 volts.
