For a three-phase, four-wire, system, the line voltage is measured between any pair of line conductors, while the phase voltage is measured between any line conductor and the neutral conductor.
For a three-phase, four-wire, system, the line voltage is numerically-equal to the phase voltage, and both are measured between any pair of line conductors.

What is the Single phase voltage in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line
How do you calculate 440v phase?
Let's get the terminology correct. A 'phase voltage' is measured across a phase, whereas a line voltage is measured between two lines. So there is no such thing as a 'phase to phase' voltage -it's a line to line voltage (hence the term 'line voltage').
Why is three phase voltage 400 V when single phase is 230 single phase 1.73 3 phase. what is 1.73?
I will try and make this as simplified as possible. The secondary side of transfomers are connected in star - which means there is a neutral / earth connection. If you measure between a LINE to LINE ('line voltage') voltage you will measure 400V, but now we have introduced the neutral / earth and we measure between LINE to NEUTRAL ('phase voltage) 's LINE to EARTH we will get 230 V. The reason for this is that, because the phase voltages are displaced, in time, by 120 electrical degrees, you must add them vectorially to obtain the line voltage. And the vectorial sum of two 230-V phase voltages, displaced by 120 degrees, is 400 V -or 1.732 times either of the phase voltages.
What is 11 kV single phase?
for USA, Canada and other countries running a 60 Hz supply service.A 11kV single phase line is one phase of a three phase system. The three phase system voltage is found by multiplying 11kV x 1.73. The three phase primary system voltage is 19kV. A transformer with a 11 kV primary can have a secondary of 115/230 depending on the internal connections in the transformer's case.For the UK11 kV is the standard three-phase h.v. distribution voltage in the UK, where it is a line voltage (i.e. it is the voltage measured between any pair of the three line conductors). A single-phase distribution transformer is connected between any two lines, so 'single-phase 11-kV' is simply a connection made between any two lines of an 11-kV three-phase system.As the primary windings of three-phase 11-kV distribution transformers are delta (3-wire) connected, the primary phase voltage is numerically equal to the primary line voltage (11 kV).
What voltage you get at home in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line
Three phase voltage in india?
It is 230V single phase and 440V in 3 phase system at 50 Hz.AnswerIf 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.
Does a clamp-on ammeter measures voltage?
No, it will only measure the current through a single phase.
What is the Single phase voltage in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line
How do you calculate 440v phase?
Let's get the terminology correct. A 'phase voltage' is measured across a phase, whereas a line voltage is measured between two lines. So there is no such thing as a 'phase to phase' voltage -it's a line to line voltage (hence the term 'line voltage').
What will happen if you use phase to phase voltage for a single phase device?
If a single-phase device is connected to a phase-to-phase voltage, the device may get damaged due to the higher voltage applied. Single-phase devices are designed to operate at a lower voltage compared to phase-to-phase voltage levels typically found in three-phase systems. It is important to match the voltage ratings of the device with the supply voltage to prevent damage.
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 3 phase voltage in Germany?
Three-phase voltage in Germany is 400V, single-phase voltage is 230V.
What is typical single phase voltage in Canada?
The typical single phase voltage in Canada is 120 volts.
How do connect no of 1phase lamp series connection in 3phase?
Your question is not clear. Are you asking how you can obtain a single-phase supply from a three-phase system? If so, then it depends on the type of three-phase supply and the voltage you require. For example, a three-phase, three-wire, system, single phase is obtained between any two line conductors. For a three-phase, four-wire, system, single phase is obtained either between any two line conductors, or between any line conductor and the neutral conductor. In the case of the latter, two voltages are available, a line voltage and a phase voltage, with the line voltage being 1.732 x larger than the phase voltage.
What is voltage phase to phase 380 3 phase?
Voltage phase to phase in a 380V 3-phase system refers to the voltage measured between any two of the three live conductors in the system. In a balanced 3-phase system, the phase to phase voltage is equal to the line voltage, which is 380V in this case. This voltage is commonly used in industrial and commercial applications to power heavy machinery and equipment. It is important to note that the phase to phase voltage is higher than the phase to neutral voltage in a 3-phase system.
Is transmission line voltage phase to phase?
Yes usually it would be phase to phase voltage because most transmission lines are set up in a delta configuration. This means that there is no neutral conductor to use as a reference. So any voltage would be measured with reference to another phase.CommentLet's get the terminology correct. The voltages between the three 'hot' lines of a three-phase, three- or four-wire, system are called 'line voltages' even though, in the case of a delta-connected system, they are numerically-equal to the corresponding phase voltages. Therefore, we call the conductors 'line conductors', not 'phase conductors'.There is simply no such thing as a 'phase-to-phase' voltage. Just think about it; you can only measure a voltage acrossan individual phase, so how can you possible measure a voltage 'phase-to-phase' -I mean, where would you place a voltmeter to do that?For a delta system, the line voltage (or line-to-line) voltage is numerically equal to the phase voltage (notphase-to-phase). For a star (or 'wye') system, the line voltage is equal to 1.73 x the phase voltage.
How do you find out PF in single phase?
Measure the voltage, current and power. The PF is power/(volts x amps).
