You cannot have 380 V between 'phases'. You can, on the other hand, have 380 V 'between lines'! '380 V between lines' refers to the voltage measured between any pair of line conductors in a three-phase system.
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.
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
The most typical three-phase voltage used in China is 380 V.
No, the voltage of 500 volts is too high to operate a 380 volt motor.
any one of the three line to neutral is 220 volts
Do you mean 'per phase' or do you mean 'per line'? The conductors that connect a three-phase supply to its load are called 'lines' not 'phases'. If you mean 'per line', and the load is balanced, then you can manipulate the following equation to make the line current (IL) the subject: power = 1.732 EL IL (where EL = line voltage = 380 V) If you really DO mean 'per phase', then it's necessary for you to specify whether the load is star (wye) or delta connected.
No.

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.
A 15 KVA - Generator operating at 380 Volts can cater to only 22.79 Amps. It cannot cater to a 60 Amps breaker

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.
It will be a 12 volt battery.
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 รท sqrt 3 = 380 รท 1.732 = 220 volts.
Dear Sir,I want to know that how much draw starting current of 380 volts 3 phase 50 hertz AC motors as per rating values?
There will be a significant reduction in the mechanical power output available from the motor.
No 380 volts is too wide a spread to use a 220 volt motor on.
