What is the relationship between phase and line voltage in a 3 phase generator?

The Voltage produced by the generator will be like 3 sets of your home's voltage (assuming we're looking at an outlet and not the 220V at the brkr box).
Each phase (sinusoidal wave) will be separated by 120 degrees, so when the 1st phase starts the 2nd phase will start 1/20th of a second later. The 3rd phase then starts 1/40th of a second later, and the 1st phase starts again 1/60th of a second later which is the beginning of the second set of sin waves. This of course is based on the N. American Frequency of 60 hertz which is 60 cycles (waves) per second.
AnswerFor a three-phase, three-wire, system the line voltages will be identical to the phase voltages.
For a three-phase, four-wire, system the line voltages will be 1.732 times the value of the phase voltages.

∙ 11y agoPhase 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.

What is phase voltage and line voltage in star connection?
The conductors that connect a three-phase supply to its load are called 'line conductors' or, more simply, 'lines'. The individual generator stator windings, transformer winding, or loads are called 'phases'. Lines and line terminals are identified by colours, letters, numbers, or combinations of letters and numbers. For example, A-B-C. Phases are identified by using the letters assigned to the line terminals between which the phases are connected, e.g A-B, B-C, and C-A. Voltages measured between lines ('line-to-line') are termed 'line voltages', and currents that pass through the lines are called 'line currents'. Voltages measured across a generator's windings, transformer windings, or individual loads, are called 'phase voltages', and the currents that pass through these are called 'phase currents'. For a three-phase, three-wire, system, the phase- and line-voltages are numerically-equal to each other. For a three-phase, four-wire, system, the line voltage is 1.732 times larger than the phase voltage.
How many volt each phase in three phase?
600 volts between any two wires. The phase has nothing to do with voltages, only current relationship.
Can a 30 K W gas emergency generator support a 200 amp residential service with a voltage config of 220 120 volts?
Need to know what voltage the generator is outputing. The maximum voltage a 15kW generator will support at 200A is dependent on service voltage and configuration, the rated generator voltage, the power factor and the load frequency. If this is a typical service to a residential unit, eg. 220V single phase, then the generator will not be able to safely support 200A.
Is transmission voltage a phase to phase voltage or a phase to ground voltage?
Phase to Phase voltageCorrection to the above answer:There is no such thing as a 'phase-to-phase' or 'phase-to-ground' voltage. The correct terms are 'line-to-line' (or 'line voltage') and 'line-to-ground' (or 'phase voltage'). Transmission-line voltages are line-to-line (or 'line') voltages.
Is a Line voltage understood to be any voltage?
The Line normally refers to the live wire in a single-phase system and the three live wire of a 3-phase system. In a 3-phase system the line voltage is usually quoted as the nominal voltage, and that is the voltage between any two of the live wires. The voltage between one of the lines and neutral is 1/sqrt(3) times less.
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.
Can a diesel generator for elevators run on single phase?
If the elevator has a single-phase motor, the diesel generator can also be single phase provided the voltage and VA ratings are compatible.
How many amps for 1010 KVA generator per phase?
To answer this question the voltage of the generator must be given.
How many kva is needed to draw 550A in a 3 phase generator?
The voltage of the generator needs to be stated to give an answer.
How do you wire a three phase four wire generator for single phase output?
In a three phase four wire system - voltage between any one phase and the neutral is single phase. Hence the single phase equipment or load between any one phase and the neutral.Another AnswerA single-phase load can be connected either between any line conductor and the neutral conductor, or between any pair of line conductors. The choice is dependent on the voltage rating of the load, which must match either the phase voltage (line-to-neutral) or line voltage (line-to-line) -these values will be indicated on the machine's nameplate.
What is the phase relationship resistor and voltage?
inversily propsanational
Does kva equal voltage x current x 1.73 for a 3 phase generator?
Yes, but only for balanced loads (current in all three phases the same value). The voltage value used is the phase to phase voltage.
What generator is suitable for a 2 HP single phase motor?
Any single-phase a.c. generator producing more than 2.5 HP or 2 kW - at the required voltage.
What size of wire to use for 1015 kva ac generator?
To answer this question a voltage must be given to find the current output. Also whether the generator is three phase or single phase.
How match 2 phase line voltage between them?
To match 2 phase line voltage it has to be the same voltage.
What is the phase voltage inside a motor if one phase is lost and what is the voltage between the other two phases?
The phase voltage is usually constant and determined by the supply voltage.
What is the residual voltage of a 380Vac 264KW generator?
Residual voltage is the vector sum of all three phase voltages. Ideally this will be zero.
