What is the line voltage between two lines?
the voltage between 1 line & phase =120v The voltage between 2 line =240
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 match 2 phase line voltage between them?
To match 2 phase line voltage it has to be the same voltage.
What is the relationship between phase voltage and line voltage?
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
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.
What is the relationship between voltage instability and reactive power?
Voltage is a function of reactive power becouse normally X is greater than R between 2 nodes, so the voltage of a line is determined by X, wich on the other hand depends from reactive power Q
Explain the relationship between staff and line authority?
what is the relationship between staff and line authority?
What is the difference between line relationship and staff relationship?
The difference between line relationship and staff relationship is that, line relationship receives command from the top management, while staff relationship is managed by all staff.
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.
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'!)
What is 1.73 in electrical formula?
1.732 is the square-root of three (and is often written that way in the relevant equations), and the relationship between a three-phase, four-wire, system's phase and line voltages. That is, the line voltage is 1.732 times greater than the phase voltage, and the line current is 1.732 timesA three-phase, four-wire, system is provided by, for example, a transformer, whose secondary windings are connected in a consideration called 'star' or 'wye'. This configuration provides four conductors: three 'line conductors' and one 'neutral conductor'. The voltage measured between any pair of line conductors is called a 'line voltage', while a voltage measured between any one line conductor and the neutral conductor is called a 'phase voltage'. The relationship between these voltages is:VL = 1.732 x VPThere is a similar relationship for the currents flowing through a 'delta' (or 'mesh') load -provided the load is balanced (i.e. each phase load is identical). That is, the line currents supplying that balanced load will be 1.732 times larger than the phase currents flowing through the individual loads.
What is phase voltage and line voltage in star connection?
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.
