The conductors between a three-phase supply and a three-phase load are called line conductors not phase conductors, and the voltage measured between them are line voltages, not phase voltages. In the case of a delta supply, the line voltages are numerically equal to phase voltages, but the name remains the same!
I have to admit that many people call line conductors 'phase conductors', but many people also say 'irregardless' -that doesn't make it a real word!!

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.
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. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line.
Is 220V line voltage or phase voltage?
Phase, if you are referring to line, as power line from pole.
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.
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).
What is the line voltage between two lines?
the voltage between 1 line & phase =120v The voltage between 2 line =240
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.
Is line to line voltage equal to line voltage?
Yes. By definition, a line-to-line voltage is indeed called a line voltage.For delta-connected, three-wire, systems comprise three line conductors. The line voltage is numerically equal to the phase voltage.For wye-connected, four-wire, systems comprise three line conductors and a neutral conductor. Any line-to-neutral voltage is called a phase voltage. The line voltage is 1.732 times the value of the phase voltage.
What is the voltage to ground of 13800 volts line to line?
On a three phase system with a line to line voltage of 13800, a wye connection will give you a voltage of, 13800/1.73 = 7977 volts to ground.
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?
Line to line voltage is not the same as line to neutral voltage because line voltages are 120 degrees apart. They are related by: Line to neutral voltage * tan (120 degrees) = Line to neutral voltage * 1.73.Additional CommentFor delta-connected systems, the line voltage is the same as the phase voltage.For wye-connected systems, the line voltage is larger than the phase voltage by a factor of 1.732. The reason for this is as follows:Because any two phase voltages are displaced from each other by 120o, they must be added vectorially, not algebraically, to find the line voltage. As the above answer points out, this means that the relationship between the two is the square-root of 3, or 1.732.
