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)

How do you obtain a 230 volts single phase supply from a 400 volts three phase four wire supply?
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.
How many amps does a 22 KW generator produce?
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.
Which device runs on 400 volts?
A motor will operate on 400 volts.
What is the 400 volts system?
The 400 volts system is a three-phase electrical power system commonly used in industrial and commercial settings for efficient energy distribution. It typically refers to a three-phase supply with a voltage level of 400 volts between the phases, often encountered in Europe and other regions. This system allows for the operation of heavy machinery and equipment, providing a balance between power capacity and safety. It is also used for lighting and heating applications in various facilities.
400 volts x 45 amps?
Multiplying 400 volts by 45 amps would give you a power output of 18000 watts, which is equivalent to 18 kilowatts (kW).
What is the most typical industrial three-phase voltage in Thailand?
The most typical three-phase voltage used in China is 380 V.
What is 3 phase voltage in turkey?
The 3 phase power in turkey is either 380 VAC or 400 VAC.

What is voltage phase to phase 380 3 phase?
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.
What is 381 rounded to the nearest ten?
380
Can 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?
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.
How many amps does a 22 KW generator produce?

What is percent change from 380 to 400?
It is: (400-380)/380 times 100 = 5.263% increase to three decimal places
What is 391 to nearest hundred?
400.
Which device runs on 400 volts?
A motor will operate on 400 volts.
What does 400-20?
400 - 20 = 380
How do you connect 400 volts in Singapore?
Singapore uses a 400/230-V three-phase, four-wire, system. 400 V is achieved by connecting a load between any two line conductors.
