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.

∙ 11y agoIn a three-phase system, a line voltage is the voltage measured between any pair of line conductors. The line current is the current flowing in any of the lines. Line voltages are usually numerically equal when measured between any pair of lines. Each line current, however, may be different if the load is unbalanced, or the same if the load is balanced.
In a residence, the line voltage is the voltage between the incoming line conductor and the incoming neutral conductor. The line current is the current flowing the the line conductor to the load.

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?
The term, 'unbalanced system' refers to an unbalanced load. Under normal circumstances, an unbalanced load leads to unbalanced line currents. The line voltages are determined by the supply and remain symmetrical, even when the load is unbalanced. As your question refers to a 'line to neutral' voltage (i.e. a phase voltage), you must be referring to a star (wye) connected load, in which case the phase voltage (line to neutral voltage) is 0.577 (the reciprocal of the square-root of 3) times the line voltage (line to line voltage).
How match 2 phase line voltage between them?
To match 2 phase line voltage it has to be the same voltage.
What voltage should 208 3 phase leads read?
From line-to-line (any two of the three leads) voltage or 'line voltage', the voltage is 208 V. The line-to-neutral (one of the three leads and the neutral conductor), or 'phase voltage', is 120 V.
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'!)
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.
What is edge speed in electronics?
A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line. A voltage is applied to a signal line.

Is 220V line voltage or phase voltage?
Phase, if you are referring to line, as power line from pole.
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 line voltage between two lines?
the voltage between 1 line & phase =120v The voltage between 2 line =240
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 line regulation?
Line regulation is a measure of the ability of the power supply to maintain its output voltage given changes in the input line voltage. Line regulation is expressed as percent of change in the output voltage relative to the change in the input line voltage.
How match 2 phase line voltage between them?
