What is the Phase to neutral voltage on a 400 volt 3 phase power supply?

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 voltage in a wye system is always the phase voltage multiplied by the square-root of "3" (1.732) and reflects the vector sum of two individual phase voltages present in a three phase system.
Thusly, if the line voltage is "400V", then the phase voltage is 400V divided by the square-root of "3" (1.732), which is 230V.
Examples of this for North American power systems are 120/208V, 277/480V and 347/600V. Examples for other areas of the world are 220/380V, 230/400V and 240/415V.

If in the three phase connection phase to phase voltage is 400v what will be the phase neutral voltage?
The formula to use is, phase voltage /1.73 = phase to neutral (ground) voltage.CommentThere is no such thing as a 'phase to phase', or 'phase to neutral' voltage. The correct terms are 'line to line' and 'line to neutral'. So the above answer should read: line voltage/1.73= line to neutral voltage = phase voltage.
Why floating neutral in a three phase supply is undesirable?
Floating neutral in 3 phase supply is undesirable as if the same thing occurs then there will be bad effect for all single phase equipment which we are using as phase to neutral voltage will exceed from its normal value and it will harm the equipments.
What is the voltage for a single phase from a 415 volt 3 phase and neutral supply?
240V. 415 / 1.73 = 240
Can you convert 415v 3 phase to 230v single phase?
415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
How three phase line current convert in single phase?
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.

What is the voltage for a single phase from a 415 volt 3 phase and neutral supply?
240V. 415 / 1.73 = 240
Can you convert 415v 3 phase to 230v single phase?
415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
How you can convert 1-phase voltage to 3-phase voltage and vice-vars a?
A single-phase supply is obtained between any two line conductors or between a line and neutral conductor of a three-phase supply. To obtain a three-phase supply from a single-phase source is far more difficult, and requires additional equipment.
What is the total of a phase to earth voltage on 11000 volts?
To calculate phase-to-earth voltage on a 11 kV system, divide the voltage by the square root of 3 (1.732). So, the phase-to-earth voltage would be around 6350 volts.
Can you use phase voltage as a single phase?
A single phase supply can be obtained between any pair of line conductors or between a line conductor and a neutral conductor.
How three phase line current convert in single phase?
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.
When phase and neutral will short means what will be the voltage in neutral?
If the phase and neutral wires are shorted together, the voltage in the neutral wire will be the same as the phase voltage. This is because the short circuit effectively bypasses any impedance or resistance in the circuit, causing the potential difference between the phase and neutral wires to be equal.
How do you calculate low phase voltage of a three phase four wire system without using voltmeter?
The formula you are looking for is - phase voltage/1.73 = phase to neutral voltage.
HOW and Why there is 440v supply in three phase and 230v supply in single phase?
In a three-phase system, the voltage is measured between any two of the three phase conductors. The voltage between two phases in a 3-phase system is higher at 440v compared to a single-phase system where the voltage is measured between one phase and a neutral wire, resulting in 230v. The higher voltage in three-phase systems allows for more power to be transmitted efficiently over long distances.
What is typical single phase voltage in Canada?
The typical single phase voltage in Canada is 120 volts.
