"The voltage isn't lost. Its lower because the phases in sires are out of phase."
So help me out here again. If delta is produceing 10 volts. Star will produce 17.3 volts.
If the phases were in phase the voltage would be 20v (10 + 10) no phase diferance. You've said the phases are shereing the voltage.
Where did the 2.7 volts go and who are the out of phase phases shereing it with shairing with cause it must not be the batteries?
Like I said. If I wire two 10 volt 10 amp single phase transfomers in sires I get 20 volts 10 amps. But if the same 2 transformers are 120% out of phase I get 17.3 volts at 10 amps. Wheres the addvantage in loosing that 2.7 volts?
As you've stated. Star makes 1.73 X the voltage of delta.
Delta or perelell does not have this voltage loss because there is not out of phase condition that exsists.
So lets take those same 10 volt 10 amp phases this time and wire them star. The amperage should remaine 10 a because 10 amps in sires with 10 amps is still ten amps but the voltage goes up.
Example if I had 2 10v 10 batteries wired in sires the voltage would be 20v but the amperage would still be 10a. star is sires.
However since were talking about 3 phase or 120% out of phase the voltage is only 17.3v. 17.3v X10 amps 173 watts.
Now lets rewind some coils and make each phase do twice the voltage 20 volts using wire half the size of star. The amperage will drop to 5 amps per phase. Half the size of wire twice the turns. So we end up with three 5 amp phases for a total of 15 amps but the voltage is now 20v. because in delta the phases are in perelell so the voltage remains the same.
15 amps X 20 volts or 300 watts.
If the voltage isn't lost in star then it must be 20v or higher. But you said its not 20 but 17.3. If the amperage isn't the same as the amperage of one phase then what is it?
Even if the voltage is 20v or higher what is the amperage? I don't think the amperage of phases wired in sires can be higher then phases wired in perelell through the delta conection.
Is the amperage of phases wired in delta 1.73X the amperage of star? What is the amperage compairisons? I know its said to be more, how much more?
For star to do the same wattage we need the same amps and volts. That means the 10 volt phases will have to produce 20 volts wired star and the 10 amp phases will have to produce collectively (star sires phases) 15 amps?
Again Dan if the star phases are shareing the 20 volts and only giving us 17.3v were is the 2.7 volts going. I think thats about 1/8 lost or a littel over.
We start out with 20 volts and end up with 17.3v I think that a loss. And if it isn't lost how can you put in 20 and get out 17.3?
I prefure to put in 20 and get out 20.
