480V Delta Source

One additional comment: All voltage amplitudes are typical RMS magnitude values. This is just for convenience used in the utility industry sometimes. Actual values are 1.414 times higher.

This App migth do a lot wrong, but this little problem is perfectly solved by Everycircuit. Check that again. Run simulation till green trace is a full 360° periode, take your time. Then compare blue and orange with green, ±120° shifted. One is late and the other one is ahead in time. For the one which is late you see perfetly its appeares after the 90° maximum around 120°. The one which is early you need to watch at the !ende! of the green reference and go back in time to the left in trace/time, voila again right before the 90° minimum of green reference you can see 120° shifted sine wave. Yes, the interpretation of plus minus ± is questionable, but fact is around 0° reference green sine wave we have two ±120° shifted sine waves!!!! App again not guilty, sorry. http://everycircuit.com/circuit/5778879942492160

Hurz you made a wye 3 phase voltage source. I am attempting to simulate a delta 3 phase source. It doesn't look smooth as you have stated because there is subtransient DC from the transformer magnetizing inrush current. Also the app makes the current look not 120 degrees sequence. However if you wait about 30 cycles, smooth waveform is ahead. Vab first then Vbc then Vca. In text books usually it's Vca as the refernece voltage for DELTA source. Please look up delta connected 3 phase sources to see more info.

Its a delta and you said its impossible todo so. Here we are with a delta or triangle (actually it doesn't matter for your phase issue how the loads are ordered, we anyway take just a look at the applied voltages at three corners. Wye or delta corners are equal in voltage, but NOT IN CURRENT, look again. Transformer? my is smooth very smooth, dont know where you see something discontinue!?! Inrush is not wanted, but even can be avoided or minimized, if you kown how and want. But in my circuit is no inrush, cuz there are no transformers. "does not look 120°", so measure it or continue guessing, how much you guess >90 <180, so 120 is within this range, voila? If you wait and it does change, its your circuit cuz you have used voltmeters. I havn't in my circuit it does not happen! Voltmeters do have this ugly behaviour, thats the reason i built a new circuit for you without anything what makes trouble. Anyway, have you even watched my cirucit longer then 1s? Or cant you open it at all? iPhone user? For nameing convention it might give some irritation. I talk about delta and mean also triangle, while Star is Y and Y is wye cuz it looks and sounds like a "why". Right? So check again and please dont blame this cool app to quickly at the wrong place and point of time in your knowledge development phase. From experience with hundreds of newbies i know they are sometimes to quickly in its rootcause speculations. Ps. Everycircuit uses peak values for AC source, thats a fact and can be quickly accepted, cuz its always not what you want, according to murphys law. So my tipp for you, take your book again and start reading first, before asking, thanx. And check my circuit

Another missunderstanding on your side. Mains are only available in wye or star or delta or ∆ or triangle all in one, cuz we just look at takeover points in Voltage. POINTS and not connections or currents. As i already mentioned, the corners of ∆ are identical in voltage of peak-ends of Y or wye or star! ONLY THE CURRENT BETWEEN THE WIRES/CORNERS IS DIFFERENT. I hope you will understand after reading your Textbook again.

Hurz, if you trying to prove I am wrong then update your circuit with a delta source and repost it here. You have drawn a delta load, not a delta connected voltage source.

dont you get it? Only a load can be organized as delta or ∆ or Y. You cant organize mains as delta !!! You try the quadratur of a circle.

You're saying that wye primary and delta secondary transformers are uncommon / unstable right?
