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.
Which device runs on 400 volts?
A motor will operate on 400 volts.
400 volts x 45 amps?
400 Volts X 45 Amps = 18,000 Watts
Can 400volts heater element get supply from 230 volts?
Yes you can run a 400 volt heater on 230 volts but you will not get the full wattage rating that the heater produces at 400 volts.
How do you convert 400 amp of three phase supply into kwh?
By knowing the voltage you could use calculate the wattage. Power equals volts times amps. Divide by 1000 to get kilowatts.
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 voltage phase to phase 380 3 phase?
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 volt220 volt x 1.732 = 381 volt230 volt x 1.732 = 400 volt240 volt x 1.732 = 415 voltM.

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 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.
