By knowing the voltage you could use calculate the wattage. Power equals volts times amps. Divide by 1000 to get kilowatts.

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.
Computation of three phase motor 230 volts 20 hp in what size of wire?
The supply is probably 400 v three-phase with 230 v between each live and neutral. On this assumption the current is 49 amps and the copper cable size is 16 mm2 for a run of up to 30 metres.
What is 400 amp 3 phase 380 volts converted to KW?
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 factorSince, 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 convert 415 volts to 240 volt?
415 V is the 'line voltage', and 240 V is the 'phase voltage' of a 415/240-V three-phase, four-wire, system. These were the standard nominal voltages used in the UK before EU 'harmonisation' forced them to be 'renamed' (but not actually changed) to '400/230 V'!! So there really isn't such a thing as separate '415-V' and '240-V' three-phase systems. And there is no economic way of changing the supply frequency to a different frequency. Incidentally, the symbol for 'hertz' is 'Hz', not 'htz'.
Explain briefly the difference in application between single and three phase distribution installation?
A simple single-phase installation for an average European house has a supply provided on two wires, the live and the neutral, with a nominal voltage of 230 v. Single phase supplies are usually rated at 60 or 100 amps. In countries which use 120 v appliances the property is usually supplied with a split single-phase system on three wires, with one neutral and two lives. The voltage across the live wires is 240 v for high-power appliances, while neutral to either live wire is 120 v for lighting and low-power devices. The common European three-phase system has one neutral and three live wires with 230 v between neutral and each live wire, but 400 v between live wires. Groups of houses and other small properties have a three-phase supply, with each property connected through a single-phase spur using one live wire and neutral. Large houses and small businesses might each have their own three-phase four-wire supply.
How convert 1 phase to 3phase in aircraft?
The power is generated in the form of three-phase in aircraft, and this sytem has no problem in feeding single phase loads. To conserve mass in tansformers and motors the supply works at 400 Hz.
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.
Can you use three phase power for a dwelling unit service?
noAnswerWhereas most countries have single-phase residential supplies, some countries, such as Cyprus, often have three-phase supplies. The main distribution panel ('consumer unit') must be designed and assembled to accommodate either a single-phase supply or a three-phase supply; you cannot use a single-phase distribution panel with a three-phase supply.
If you have a three phase motor with 400 v supply and 0.65 ka what the overload?
Any value over .65kA will be classed as an overload.
What is the 3 phase power supply in sri lanka?

What is the full load current of a 50 hp three phase ac motor operating at 230 v?
Assuming you can get a three-phase 230 v supply, which has 133 v between neutral and each live, the full-load current assuming a 30% increase for power-factor and efficiency considerations would be 120 amps. In Europe the standard three-phase supply is 400 v. In the US three-phase supplies are normally 208 v or 480 v and an alternative option is a 240/480 v split-phase (single-phase) supply.
Can the star point of a 400 volt three phase generator be grounded to produce 240 volts?
A 400/230-V three-phase generator hase three line terminals, together with a neutral terminal. The line voltage (i.e. the voltage between any pair of line terminals) is 400 V, while the phase voltage (i.e. the voltage between any line terminal and the neutral terminal) is 230 V.
Why AC three phase apparatus are more popular compared to single phase?
the main advantage of having three phase supply is that the total load of house or a factory is divided into three pars so that none of the line is over loaded.moreover the three phase also provide 400 V which can also used to operate some special appliances.
Can use 400VAC 3-Ph industrial socket on 230VAC 3-pH supply?
The common European supply voltage is 400 v three-phase. That is the voltage between live lines, and there is 230 v between neutral and each live line. A 230v three-phase supply would have 173 volts from live to neutral and that kind of supply is extremely rare.
How can three types of supply be obtained from the secondary side of a delta star transformer where the supply voltage is 11000 V?
The standard three-phase distribution transformer in the UK is a delta/star connection with a rated primary line voltage of 11 kV, and a nominal secondary line voltage of 400 V, giving a secondary phase voltage of 230 V.So, the secondary provides a three-phase, four-wire, system comprising three line conductors and a neutral conductor. The line-to-line (line voltage) voltage is 400 V and the line-to-neutral (phase voltage) voltage is 230 V.There are not 'three types' of supply obtained from this arrangement.
How do you convert 3phase connection to 2 phase?
Any two legs of a three phase system can be classed as a single phase supply.Alternative AnswerAs the above answer points out, connecting a load between any two line conductors of a three-phase supply will give you a single-phase load. But you must, of course, take into account the voltage rating of the load you wish to connect.In Europe, three-phase low-voltage distribution is normally by means of a four-wire system, comprising three line conductors and a neutral conductor, operating at 400 V (line-to-line) and 230 V (line-to-neutral).Your single-phase load's voltage rating must, of course, match either the single-phase supply's line-to-line or line-to-neutral voltages. In Europe, most single-phase loads are rated at 230 V so, for a residential three-phase, four-wire system, it is usual to obtain a single-phase supply by connecting the load between any one of the line conductors and the neutral conductor.But, if you have a non-standard, 400-V single-phase load, then connecting that load between any two line conductors will also give you a single-phase supply.
How do you convert line current to phase current?
The current is the same in the three live wires. The voltage can be described as the line voltage (phase to neutral) or the phase voltage (phase to phase) which is larger by a factor of sqrt(3). So a line voltage of 230 v corresponds to a phase voltage of 400 v.
