Why is 3 phase power advantageous in higher voltage applications?
Kumoyume
The 3 phase electric power is very common way of electric power transmission. Three circuit conductors carry three alternating currents the first conductor as reference the other currents are delayed in time for 1/3 and 2/3 of the cycle of the electrical currents.

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'!
In 3 phase voltage increases and current decreases why?
If the load current descrease, there is less voltage drop caused by the resistance of the wire, so the voltage is higher.
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.
What is the Single phase voltage in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line
In a 3 phase 480 panel what voltage should you get phase to phase?
The voltage you are referring to is a 'line-to-line' voltage ('line voltage'), as there is no such thing as a 'phase-to-phase' voltage.480 volts. In real life, the voltage will vary slightly by up to 3% (14 V) on a properly sized circuit. Line to neutral will measure 277 volts, plus or minus 3%.
What is the three phase voltage in Pakistan?
Pakistan has a 220 v 50 Hz domestic supply and the three-phase voltage is sqrt(3) times higher, or 381 v. Higher voltage are also used for three-phase power transmission.
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'!
What is the use of 240 three phase delta?
240 volt delta systems were used a lot in automotive garages and small manufacturing facilities. This system works great for motor loads because of the phase to phase voltage of 240 vac, motors run better (lots of motors were manufactured to operate on 240 only) on the higher voltage compared to 208 vac. Also the availability of 120 vac on the same system was a plus, however on a delta system you have one phase with a higher voltage to ground (high leg) usually about 190 vac. You have to be careful not to use this phase in certain applications.
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 will be the resultant voltage if the two phase voltage having no phase difference?
If two phase voltages are the same voltage and the same phase angle, the the resultant voltage will be twice the voltage.
In 3 phase voltage increases and current decreases why?
If the load current descrease, there is less voltage drop caused by the resistance of the wire, so the voltage is higher.
Can a 415volt 3phase motor run on 525 volt 3 phase?
It is not advisable to run lower voltage motor on a higher voltage.
What will cause my voltage to be higher on one phase and lower on the other?
If secondary side of the 3 phase transformer has any issue, it would result unbalanced voltage between phases. Other reason could be if the load on one phase is highly different than other phase, it also would result in unbalanced voltage.
What is power cable size for 1 kw 1 phase motor over 500 meters?
It depends on the voltage that the motor needs, because a higher voltage requires less current for a given amount of power. Also a higher voltage can tolerate a higher voltage drop. So there are two things that lead to a thinner wire when the voltage is higher.
What is 3 phase voltage in Germany?
Three-phase voltage in Germany is 400V, single-phase voltage is 230V.
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.
Why is there change in terminal voltage as load applied to a three phase alternator?
The AVR (Automatic Voltage Regulator) control the DC field voltage to the rotor of the alternator, as soon as higher load is demanded from the alternator, the AVR output voltage go higher, hence, a higher AC voltage on the output of the alternator. If the voltage go to high then the AVR is faulty.
