Whenever we specify voltages and currents in a three-phase system, unless otherwise stated, we always refer to line values. 'Lines' (or 'line conductors') are those conductors that connect a three-phase supply to its load.
So the '400 A' and '380 V' quoted in the question are line values (as opposed to phase values).
The equation for the power of a three-phase load is given by:
P = 1.732 x line voltage x line current x power factor
Since, in your question, you make no mention of power factor, we shall assume that the power factor is unity (i.e. the load is purely resistive) and, so:
P = 1.732 x 380 x 400 x 1 = 262 272 W (or 262 kW)
400 volt three phase on a grounded system is 230 volt single phase, with each phase 120 degrees apart. So, if you have a 400 volt, three phase four wire service (grounded service), you can pull one phase off and reference to the neutral for 230 volt service. Note this may not allow 115 volt service, unless there is also a center tap for each phase.
To determine the amperage produced by a 22 kW generator, you can use the formula: Amps = Watts / Volts. For a three-phase generator operating at 400 volts, the calculation would be 22,000 watts / 400 volts = 55 amps. For a single-phase generator operating at 230 volts, it would be 22,000 watts / 230 volts = approximately 95.65 amps. Therefore, the amperage output depends on the voltage used.
A motor will operate on 400 volts.
Multiplying 400 volts by 45 amps would give you a power output of 18000 watts, which is equivalent to 18 kilowatts (kW).
This question cannot be answered without knowing the voltage. Watts=Volts x Amps In the United States mains voltage (what you get in your house) is 120 Volts, so 120 x 400 = 48,000 Watts In Europe mains voltage is 230 Volts, so 230 x 400 = 92,000 Watts
The most typical three-phase voltage used in China is 380 V.
The 3 phase power in turkey is either 380 VAC or 400 VAC.

Voltage phase to phase in a 380V 3-phase system refers to the voltage measured between any two of the three live conductors in the system. In a balanced 3-phase system, the phase to phase voltage is equal to the line voltage, which is 380V in this case. This voltage is commonly used in industrial and commercial applications to power heavy machinery and equipment. It is important to note that the phase to phase voltage is higher than the phase to neutral voltage in a 3-phase system.

No, you can not you change the wiring of a single phase appliance of 2.4 kw that works on 240 to 400 volts 3 phase 60 Hz supply. They are two different electrical systems.
To determine the amperage produced by a 22 kW generator, you can use the formula: Amps = Watts / Volts. For a three-phase generator operating at 400 volts, the calculation would be 22,000 watts / 400 volts = 55 amps. For a single-phase generator operating at 230 volts, it would be 22,000 watts / 230 volts = approximately 95.65 amps. Therefore, the amperage output depends on the voltage used.
It is: (400-380)/380 times 100 = 5.263% increase to three decimal places
400.
A motor will operate on 400 volts.
400 - 20 = 380
Singapore uses a 400/230-V three-phase, four-wire, system. 400 V is achieved by connecting a load between any two line conductors.
