What is voltage phase to phase 380 3 phase?
380 volts 3-phase generally means 380 volts phase-to-phase. To find the phase-to-neutral voltage, divide by sqrt(3), which would be 220 volts.
The three phase voltage is 380 the hertz is 50
380 voltage and 60HZ

In a wye connection 220 volts is the line to neutral voltage of 380 volts. 380/1.73 = 220. The voltage of 220 volts will appear between L1 - N, L2 - N and L3 - N. All of these connections are classified as single phase connections.
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 volt 220 volt x 1.732 = 381 volt 230 volt x 1.732 = 400 volt 240 volt x 1.732 = 415 volt M.

Answer for UK and countries running a 50 Hz supply service. The voltage potential of 380 volts is not common to North America. It will probably be difficult to tap into the plug to get the voltage. If you have a three phase 380 volt supply from a source then you can obtain a single phase voltage of 220 volts from it. 220/380 is a wye voltage connection. 380 divided by 1.73 will give you… Read More
A voltage of 380 volts is a three phase voltage. On a three phase four wire system, each phase leg to neutral (grounded) will give you 220 volts. This voltage is obtained by dividing the phase voltage by 1.73, as the phase legs are generated 120 degrees from each other. Square root of three is 1.73 divided into 380 equals 220 volts.
The process of obtaining 220 volts from 380 volts is quite simple. 380 volts is a three phase four wire system voltage. The 220 volts is obtained by taking the sq. root of 3 which equals 1.73 and dividing it into the phase voltage. 380/1.73 = 220 volts. This holds true with any three phase four wire voltage system. 208/1.73 = 120 volts, 415/1.73 = 230 volts, 480/1.73 = 277 volts and 600/1.73 = 347… Read More
Sao Paulo has 220/380 v 3-phase supplies, with many single-phase domestic outlets at 110 v. The frequency is 60 Hz.
because the phase voltage of the delta connection is more the the phase voltage is stare connection by root 3 so if we have 380 at primary u will get 220 at secondary ( i think )
The most typical three-phase voltage used in China is 380 V.
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 = 220 <><><> As 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… Read More
There are two ways. 1: You don't. 2: Use a motor/generator or something designed for the purpose. Normally we get both of these from 480 or higher voltage 3 phase power.
There is phase to phase voltage in 3 phase system. Answer You don't get voltage 'phase-to-phase'; it's 'line-to-line'!
Phase to phase voltage on a 3 phase 208 volt panel is 208 volts. From each of the three phase legs to the starpoint neutral the voltage is 120 volts. Correction to the above answer. phse to phase means the line to line voltage. phase voltage is another thing. phase to phase voltage is equal to root 3 times phase voltage. PHASE TO PHASE V = 1.73 * PHASE V The correct term is 'line-to-line'… Read More
Only with a 3 phase transformer.
Phase voltage is sqrt(3) times the line voltage, that is 1.732 times. So for a 240 v line voltage the phase voltage is 416 v.
Three-phase voltage in Germany is 400V, single-phase voltage is 230V.
6350.8 volts AC rms. The phase to earth voltage is ( square root(3) ) x lower than the phase-phase voltage on a 3 phase system.
A single phase voltage is normally the voltage between one phase of a 3 phase generator and the neutral wire.
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… Read More
Yes, a 380 v 3-phase supply is OK for that motor.
Volts divided by 1.73. The three phase system has to be a three phase four wire wye (star) system. The three phase voltage of 440 that is supplied in the question will not give you 220 volts single phase. 440/1.73 = 254 volts. To obtain 220 volts single phase, a three phase four wire system voltage of 220 x 1.73 = 380 is needed.
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.
The voltage you are referring to is a 'line-to-line' voltage ('line voltage'), as there is no such thing as a 'phase-to-phase' voltage. 480 volts. In real life, the voltage will vary slightly by up to 3% (14 V) on a properly sized circuit. Line to neutral will measure 277 volts, plus or minus 3%.
You can get a buck / boost transformer which will step down the voltage. What will be important is phase supply.
Divide by your number of phases 1 or 3 then divide by your Voltage. If its a 3 phase supply Voltage you need to divide by your 3 phase voltage for balanced loads and by your single phase voltage for unbalanced loads requiring a neutral.
How do you convert 3 phase RMS line line voltage to RMS line neutral voltage on an unbalance system Basically how do you calculate using trig for all 3 phase?
Line-to-line voltage is the phase voltage, which is sqrt(3) times the line-to-neutral voltage, known as the line voltage.
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.
The same as in single phase with the same RMS voltage.
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.
415V +/- 10% phase to phase.
There is no such thing as a 440/240-V three-phase system. If 240 V is the phase voltage, then the line voltage will be 415 V. If 440 V is the line voltage, then the phase voltage will be 254 V.
It is 230V single phase and 440V in 3 phase system at 50 Hz. Answer If the single-phase voltage is 230 V, then the three-phase voltage must be 400 V, not 440 V. The line voltage is 1.732 times the phase voltage.
Phase to phase voltage is 1.732 (the square root of 3) times the phase to star point (neutral) line voltage. e.g. if the line voltage is 220V phase voltage = 1.732x220 = 380V (approx) Additional Answer You might also like to know that the line voltage leads the phase voltage by 30 electrical degrees. And, incidentally, the correct expressions are 'line-to-line' not 'phase-to-phase', and 'line-to-neutral' not 'phase-to-neutral' (think about it, a line voltage is measured… Read More
It is probably a three phase 50 Hz motor.
The line-to-neutral (not 'phase-to-neutral'!) voltage on a 400V 3-Phase wye-connected system is 230V. Line voltage is the voltage as measured between any two (2) line conductors (hence its name!). Line voltage is often referred to as the 'line-to-line voltage'. Phase voltage is the voltage as measured between any single line and neutral. Phase voltage is often referred to as a 'line-to-neutral' voltage. "400V" on a 400V 3-Phase wye-connected power supply indicates its line voltage. Line… Read More
Use a transformer.
In a 3 phase, star connected system, the phase to phase voltage and phase to neutral voltage is calculated using root 3. That is, phase to phase voltage is root 3 times phase to neutral voltage. Also to calculate three phase power the voltage and current is multiplied by root 3 to obtain 3 phase power with unity power factor. Answer If you vectorially-add two quantities that are displaced from each other by 120 degrees… Read More
In a 3 phase system, the voltage measured between any two phase is called line to line voltage. And the voltage measured between line to neutral is called phase to neutral (line to neutral) voltage. Answer There is no such thing as a 'phase-to-phase' or a 'phase-to-neutral' voltage. The correct terms are 'line-to-line' and 'line-to-neutral'. The voltage between any two line conductors is called a line voltage. In a three-phase, three-wire, system, the line voltage… Read More
When you have 56KVA available in 3 phase supply how much is your available current in 3 phase and how much in 1 phase?
In three phase: I = (three phase VA) / (sqrt(3) x (phase to phase voltage)) for single phase: I = (single phase VA) / ((phase to neutral voltage)) keep in mine three phase VA = 3 x (single phase VA), and phase to phase voltage = 1.732 x (phase to neutral voltage) Therefore the single phase and three phase currents are the same (ie, the three phase currents are the same in all three phases… Read More
100 amps to a 3 phase load. Power = 100A x Voltage x 1.73 ((line to line voltage)(1.73=SQRT(3)). 173 amps to each of 3 single phase (line to line) loads. Power = 173A x Voltage (line to line voltage). or... 100 amps to each of 3 single phase (line to neutral) load. Power = 300A x Voltage (line to neutral voltage). Example: - 3 phase, 480v, 100amp to a 3 phase heater. 100A x 480V… Read More
In a three-phase, star- (or wye-) connected, system the line voltage (line-to-line voltage) is 1.732 (or the square-root of 3) times the phase voltage (line-to-neutral voltage). The reason for this is that a line voltage is the vectorial sum (not algebraic sum) of two phase voltages displaced from each other at 60 degrees. These days, incidentally, the UK's nominal phase voltage is 230 V, and its corresponding line voltage is 400 V.
How I can convert 220 V 3 Phase to 380 V 3 Phase
you have to provide transformer that capable to handle the 380v in to a 220v.
380 volts 3-phase has 380 volts between the lines but 220 volts between any line and the neutral. So the generator can give three separate 220 v single-phase supplies.
Three phases are: 115 volts @ 0 degrees 115 volts @ 120 degrees 115 volts @ -120 degrees Just for comparison purposes, phase to neutral voltage is: (Phase) - (neutral voltage) = (Phase) - (0) = Phase voltage So phase to phase voltage is: (Phase 1) - (Phase 2) = (Phase 1) * sqrt(3) = (115) * 1.732 = 208 volts.
Do you mean 'per phase' or do you mean 'per line'? The conductors that connect a three-phase supply to its load are called 'lines' not 'phases'. If you mean 'per line', and the load is balanced, then you can manipulate the following equation to make the line current (IL) the subject: power = 1.732 EL IL (where EL = line voltage = 380 V) If you really DO mean 'per phase', then it's necessary for… Read More
RMS volts is the same for any type of AC voltage. Divide the magnitude by sqrt(2). The difference between the 3 phase system and single phase is the sqrt(3) voltage gain that the 3 phase has.
