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.
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'!
Is 220V line voltage or phase voltage?
Phase, if you are referring to line, as power line from pole.
If in the three phase connection phase to phase voltage is 400v what will be the phase neutral voltage?
The formula to use is, phase voltage /1.73 = phase to neutral (ground) voltage.CommentThere is no such thing as a 'phase to phase', or 'phase to neutral' voltage. The correct terms are 'line to line' and 'line to neutral'. So the above answer should read: line voltage/1.73= line to neutral voltage = phase voltage.
Can an electrical short be caused a phase to a phase?
It could be a phase to phase, ph to neutral or earth fault. In single ph wiring ph to ph exhibits no short ckt faultAnswerYes, but you have got the terminology wrong. There is no such thing as 'phase-to-phase', the correct term being 'line-to-line'. So you can have a short circuit as a result of a line-to-line fault, a line-to-neutral fault, or a line-to-earth fault.
What is phase current?
A phase current is the current passing through a phase, whereas a line current is the current flowing through a line.
Can you convert 415v 3 phase to 230v single phase?
415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
What is the purpose of a phase conductor?
There is no such thing as a 'phase conductor'; the correct term is 'line conductor'. In a single-phase system, the line conductor is the energised conductor; in a three-phase system, there are three (energised) line conductors.
How do you convert 440 voltage line to voltage phase?
To convert a 440V line voltage to phase voltage in a three-phase system, you divide the line voltage by the square root of 3 (approximately 1.732). This means the phase voltage is calculated as ( V_{phase} = \frac{V_{line}}{\sqrt{3}} ). For 440V line voltage, the phase voltage would be approximately 254V.
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 the kv phase to phase for 13.8kv?
There is no such thing as a 'phase-to-phase' voltage; the correct term is 'line-to-line' voltage. Whenever you mention a value of voltage for a three phase system, it is considered to be a line-to-line voltage unless it is stated clearly that this is phase voltage (line to neutral) voltage.(The reason that there is no such thing as a 'phase-to-phase' voltage is because phases exist between, or 'across', line conductors or between a line conductor and a neutral.) That is a world wide practice for electrical power engineers.
