let me clear difference between phase voltage and line voltage. phase voltage is measure line to neutral and line voltage is measure line to line.
there is correct answer that 380 volt is sum of multiply of square root 3 to phase voltage 220 volt.
phase volt line volt
220 volt x 1.732 = 381 volt
230 volt x 1.732 = 400 volt
240 volt x 1.732 = 415 volt

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.
Can you collect one 220 volt phase from a 380 volt three phase plug?
Answer for UK and countries running a 50 Hz supply service.The voltage potential of 380 volts is not common to North America.It will probably be difficult to tap into the plug to get the voltage.If you have a three phase 380 volt supply from a source then you can obtain a single phase voltage of 220 volts from it. 220/380 is a wye voltage connection. 380 divided by 1.73 will give you 220 volts. L1 - N = 220V, L2 - N =220V, L3 - N = 220V. L1 - L2 = 380, L2 - L3=380, L3 - L1 = 380.

How can I use 380v 3 phase to power 220v 3phase motor?
f your supply is a Y connected transformer (4 wires COM) with a phase to phase voltage of 380 volts (voltage between any two of the hot wires) , utilizing a true Y connection to your load (connections of one hot lead and neutral for each phase to your load will give a voltage of 380 ÷ sqrt 3 = 380 ÷ 1.732 = 220 volts.

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.
