What is the simplest way to run a 3 phase 380 V motor of about 1 KW directly on 220 V single phase supply without resorting to rewinding or frequency converters?
You cannot run a three phase motor on single phase power. You'll burn the motor up within minutes. By the way, I've never seen or heard of a 380 volt motor. Do you mean a 480 volt motor? If so, the only way you can power it is with the correct full voltage and a 3 phase power supply.
Why is it stated - 3 phase 440 VAC when one phase voltage is 220 VAC?
In three-phase there are three live wires and a neutral. The voltage of a three-phase system is always quoted as the live-to-live voltage, and the voltage from one live wire to neutral is 57.7% of that. A 440 v 3-ph system has 254 volts between live and neutral. <<>> The question statement is not correct. Two legs from a three phase three wire 440 volt system will still be 440 but classed a single phase. On a three phase four wire system supply, the voltages will be determined by the following equation. 440/(square root of 3) 1.73 = 254 volts. The second single phase voltage attainable from this source connection is any one of the three phase legs to grounded neutral center point. This is known as a wye or star point connected voltage supply. To obtain a 220 volt single phase voltage, the three phase system would have to have a voltage of 220 x 1.73 = 380 volts.
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)
What amperage will a range with a rating of 12.9 kw draw?
This depends on what voltage the range is rated for and if it is single phase or three phase. At 220 volts single phase it is about 60 amps, 240 v single phase , 53 amps and at 480 v three phase about 15 amps.
Can you step up 220 volt AC to 380 volt AC with transformer?
Answer for UK, Europe and countries running a 50 Hz supply service.A voltage of 380 volts is not a standard North American voltage, it is a European system voltage. The 220 volts is the line to neutral voltage of 380 volts wye connected system. 380/1.73 = 220As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliancesalways use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.Further AnswerAs the original answer says, a line voltage of 380 V would result in a phase voltage of 220 V for a delta/wye transformation, but 380 V is not a standard voltage either in North America or in Europe.The standard nominal line voltage (i.e. line-to-line voltage) used throughout European three-phase low-voltage systems is 400 V. As European three-phase distribution transformers are always connected delta/wye, A 400-V nominal line voltage results in a 230-V phase voltage (line-to-neutral voltage).
What does 380 volts between phases mean?
You cannot have 380 V between 'phases'. You can, on the other hand, have 380 V 'between lines'! '380 V between lines' refers to the voltage measured between any pair of line conductors in a three-phase system.

How do you get a 220 volt single phase from 380 volt 3phase synchrounos generator?
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
What is the most typical industrial three-phase voltage in united Arab emirates?
Saudi Arabia uses both 127 V and 220 V, although the 220 V is more commonly used.

What is the equivalent to135A single phase at three phase 208V?
135 A at 120 v single-phase is 16.2 kVA. With a 208 v three-phase supply you get three single-phase 120 v supplies, so the same kVA is produced with a balanced load of 45 amps on each phase.
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.

What is the three phase voltage in Pakistan?
Pakistan has a 220 v 50 Hz domestic supply and the three-phase voltage is sqrt(3) times higher, or 381 v. Higher voltage are also used for three-phase power transmission.
What are the equations to get KVA?
If using L-L voltages, the three phase power = V*I*sqrt(3)If using L-N voltages, the single phase power = V*ITo convert single phase to three phase, multiply by 3.
What is a 208 three phase?
A 208 v three-phase system has 120 v between each live wire and the neutral. It is used in the USA as an alternative to the 120/240 v single-phase system, offering 50% more power for the same current.
