i heard that there is an electric transformer used in single phase electric furnace and other applications , its benefit is to get more balanced current load from the three phase system to feed a single phase load.i need to know how its can transform three phase supply into single phase supply, and if it can be used in reverse matter i.e can it deliver a three phase power from single phase supplythank you in advance
You would get the same voltage out of one output as if you had connected all 3. The other 2 would have lower voltages across them. For example, say the transformer was normally a 240 to 480 3-phase delta. If you were to put 240 across legs A and B, you would get 480 across A and B of the output. I believe the B/C and C/A outputs would have 240 each, since the unconnected C phase would appear as a center-tap to the A and B legs
First off: No, a transformer cannot change Single to Three phase. However you can run single phase equipment on three phase power by simply using 2 of the 3 hot lines. Depending of the voltage requirements for your machine you may need to buy a buckboost transformer to get the voltage to the correct opperating voltage of your machine (ie. a 230 v three phase input will come out at about 208 when used as single phase). If you need a conversion from single to three phase, look into buying a Phase converter. Depending on where you get it, they can be as easy as 2 lines in 3 lines out. Installed in a matter of minutes. I also recommend staying away from what is called a static phase converter. They are machine specific so if you ever change or add on it wont work. Get a Rotary one. It works with everything. Hope that helped. Good luck.
