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.


What is the amps for 400 volts and 5800 watts phase?

To calculate the current in amps (I) for a given power (P) in watts and voltage (V) in volts, you can use the formula: ( I = \frac{P}{V} ). For 5800 watts at 400 volts, the calculation would be ( I = \frac{5800}{400} = 14.5 ) amps. Therefore, the current is 14.5 amps.


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.

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.

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.
