VP = VL / √3 or VL = VP*√3. this will give you the values for a star connected system. If you using delta the VP = VL

How match 2 phase line voltage between them?
To match 2 phase line voltage it has to be the same voltage.
What is a line to line voltage?
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.AnswerThere 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 is numerically equal to the phase voltage.In a three-phase, four-wire, system, the voltage between any line conductor and the neutral conductor is called a phase voltage. The line voltage is 1.732 times larger than the phase voltage.
Is transmission voltage a phase to phase voltage or a phase to ground voltage?
Transmission voltage is typically specified as a phase-to-phase voltage, which is the voltage measured between two of the three phases in a three-phase power system. This is the standard method of specifying transmission voltages in electrical systems.
What is the line voltage between two lines?
the voltage between 1 line & phase =120v The voltage between 2 line =240
What is line voltage in star connection?
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 220Vphase voltage = 1.732x220 = 380V (approx)Additional AnswerYou 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 from the junctions between adjacent phases, so they cannot be 'phase to phase'!)
Why is phase voltage not twice line voltage?
Phase voltage is not twice line voltage in a three-phase system because the phase voltage is the voltage measured across an individual phase in a balanced system, while the line voltage is the voltage measured across any two phases. In a balanced three-phase system, the line voltage is √3 times the phase voltage, not twice.
What is the relationship between phase and line voltage in a 3 phase generator?
In a 3-phase generator, the relationship between phase voltage and line voltage depends on the configuration of the generator. In a delta configuration, the phase voltage is equal to the line voltage. In a wye configuration, the line voltage is equal to the square root of 3 times the phase voltage.
Distance maintain between phase to phase?
is there a minimum distance between 480 volt phases. ANOTHER ANSWERThere is no such thing as a 'phase-to-phase' voltage. The correct term is 'line-to-line', which is why that voltage is called a 'line voltage'. The distance between these line conductors depends on the value of the line voltage; the greater the line voltage, the greater this distance must be to prevent any flashover. These distances are specified in the utility company's standards or regulations.
Why do you have voltage to ground but not voltage phase to phase?
There is phase to phase voltage in 3 phase system.AnswerYou don't get voltage 'phase-to-phase'; it's 'line-to-line'!
What is phase voltage and line voltage in star connection?
In a star connection, phase voltage is the voltage measured across each individual phase and neutral. Line voltage is the voltage measured across any two phases in the system. The line voltage is higher (√3 times) than the phase voltage in a star connection.
What is the difference between line voltage and phase voltage?
The three 'hot' conductors supplying electricity to a three-phase load are called LINES, not 'phases' (although unfortunately the term 'phase' is widely, but incorrectly, used in the field). Phases exist between line and neutral in star, or wye, connected systems, and between lines in a delta, or mesh, connected system. Accordingly, the term 'phase to phase' is quite meaningless. A line voltage, therefore, exists between any two lines. For a star (wye) connected system, a phase voltage exists between any line and the neutral conductor. For a delta (mesh) system, a phase voltage is exactly the same as a line voltage.
Is line voltage or phase voltage mentioned on transformer nameplate?
It depends how they are connected. If they are connected between line conductors then they are measuring line voltages. If they are connected across phases then they are measuring phase voltages.
