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.
'Line currents' are those currents flowing in the line conductors, whereas 'phase currents' are those currents flowing in the phases. Each line current is the phasor sum of the phase currents at the junction between a line and two phases. For a balanced load, the line current is 1.732 times the phase current.
No. Line to line voltage is 1.732 (square root of 3) times the line to ground voltage on a properly balanced system.
YES
all the sockets are always connected in parallel,due to this the voltage across each soket is same. when any socket is open then there is no voltage loss..so the votage is same like 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.
Phase voltage is equal to the line to line voltage divided by root 3 or 1.732. So 440 L-L/1.732 = 254V. Your phase voltage is 254V.
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).
In Europe, low-voltage three-phase distribution is by means of a four-wire system (three line conductors and a neutral) supplied from a wye-connected transformer secondary. In North America, low-voltage is supplied from a delta-connected transformer secondary, one phase of which is centre-tapped and earthed (grounded). The single-phase supply to residences is then supplied by that particular phase, giving 240 V line-to-line and 120 V line-to-neutral. You can tell if you have a delta power when the phase voltage is equal to the line voltage and that you have a star power when the phase voltage =root 3(THE LINE VOLTAGE).
It depends on the type of three-phase system. If it's a three-wire system, then the phase voltage is numerically equal to the line voltage. If it's a four-wire system, then the phase voltage is numerically equal to the line voltage divided by 1.732 -in your example, this works out to be 5.77 V.

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.
The conductors that connect a three-phase supply to its load are called 'line conductors' or, more simply, 'lines'. The individual generator stator windings, transformer winding, or loads are called 'phases'. Lines and line terminals are identified by colours, letters, numbers, or combinations of letters and numbers. For example, A-B-C. Phases are identified by using the letters assigned to the line terminals between which the phases are connected, e.g A-B, B-C, and C-A. Voltages measured between lines ('line-to-line') are termed 'line voltages', and currents that pass through the lines are called 'line currents'. Voltages measured across a generator's windings, transformer windings, or individual loads, are called 'phase voltages', and the currents that pass through these are called 'phase currents'. For a three-phase, three-wire, system, the phase- and line-voltages are numerically-equal to each other. For a three-phase, four-wire, system, the line voltage is 1.732 times larger than the phase 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.
With a three-phase system the voltage quoted is the line-to-line voltage between any two live lines. To find the line-to-neutral voltage divide by 1.732 which is sqrt(3). The power supplied from each phase is the current times the line-to-neutral voltage (times the power factor if less than 1). To find the total power when the currents are equal, multiply by 3.
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.

Let's start with the correct terminology. The three energised, or 'hot', conductors are called 'line' conductors (not 'phase') conductors. which (surprise, surprise!) is why the voltages across them are called 'line voltages'.In the case of a star (wye) connected, three-phase, four-wire, system each phase is connected between a line and the neutral. And, yes, the line voltage is indeed root-3 (or 1.732) times the phase voltage.If the lines are labelled a, b, c, and the neutral is labelled N, then line voltage Vab is equal to the phasor (vector) sum of phase voltage Van and phase voltage Vnb, which are displaced from each other by 60 electrical degrees. The length of the resulting phasor is 1.732 times either of these phase voltage.
Phase, if you are referring to line, as power line from pole.
