1 Phase To 3 Phase

I'm sorry but your question does not make any sense to me.

I presume that an installation of transformers can be posed in many teaser settings. One can then choose which setting will make your product more marketable.

One can also create 3Ø electric power from 1Ø electric power with the use of phase delaying capacitors. However one must choose the capacitors to match the 3Ø load.

I doubt that either scenario I've proposed is what you are looking for an answer. Will you please clarify.

one of our engineer has asked - can we run 3 phase motor with single phase supply!

I have an idea of using teaser transformer for converting single phase supply to phase supply but i do not have an clear view whether it works or not.

As you said it is possible by using phase advance capacitors we can get 3 phase supply from 1 phase supply.

Here i am using one inducter and one capacitor. which gives the phase angle difference of 120 degrees. How ever it has some limitations, L & C values should be changed according to load to maintain proper phase angle of 120 degrees at the input of teaser transformer also 50% of the capacity of teaser transformer can be utilised.

thank you for your advice

will this work

No, this will not work because you are just driving the primary of your transformer with a single phase signal and getting a split phase output. The most common technique employed to generate three phase power from single phase power is through electro-mechanical means. (The link is just one of many vendors of this approach.) Now if you had a real 2 phase power (90° angle between voltages) then you could use a Scott-T transformer configuration. But I don't know of anywhere that still gets true 2 phase power.

thank you for your advise

I don't know what a teaser transformer is, but have you looked at this thread:

3ph Motor & 1ph Supply

hiii all,

to be precise, simply, capacitors wont do the job. if one can design an RC phase shift oscillator for power frequencies, it would be fine since these oscillators are used only in the audio frequency range so far as i know. and again, a possible solution may be to give the single phase supply to a motor which in turn drives a 3 phase generator (like in the case of Ward-Leonard system for dc motor speed control), thus u get three phase supply out of ur single phase.

another method will be to use a booster transformer, a state of the art solid state controller, a motor and a capacitor block. but this system is applicable to normal 220v ac as far as my knowledge goes. i have a schematic of it but i am unable to upload the image.

comments are welcome.
