A three phase transformer has three primary coils and three secondary coils wound on a laminated iron core shaped like the capital letter 'E'. Each pair of primary and secondary coils are wound concentrically onto each leg of the 'E'. There is a straight , laminated core segment, that connects across all three legs of the 'E', forming a circuit path for the magnetic flux.
The primary and secondary coils can be arranged as an autotransformer, with the primary and secondary coils connected end-to-end, with a common conductor tapped at the interconnection, or as separate coils with two separate connections for each coil.

∙ 12y agoIn its simplest form, it is basically two different sized coils and a temporary magnet. The ratio of the sizes of the two coils determines the voltage step, or the change in voltage output (a transformer only works for alternating current).
AnswerA basic transformer comprises two insulated coils or windings. One is connected to the supply, and is called the 'primary winding'; the other is connected to the load, and is called the 'secondary winding'. The two windings are normally wound around each other and around a laminates silicon steel 'core' which acts to maximize the flux density and the linkage of magnetic flux generated by the primary winding with the secondary winding. If the primary winding has more turns than the secondary winding, then the transformer will act to step down voltage. If the secondary winding has more turns than the primary winding, then the transformer will act to step upvoltage.
Large Transformers may have more than one primary and secondary winding, and may be immersed in oil which acts to insulate and cool the windings and other electrical connections. This oil may circulate by natural convection or, in the case of very large power transformers, by pumped around through external heat exchangers. The voltage ratio of larger transformers may be changed through the use of tap changing mechanisms.

What is the angle between no load current and the applied voltage in an ideal transformer?
A: Transformer by itself goes not alter the phases the output can be in phase or out of phase depending how you look at it.
How do you determine angle between primary line voltage and secondary line voltage of a 3-phase transformer?
You should look at the transformer vector diagram, or the type of transformer will tell you (something like YnD1, for example). If it's a Y/Y type transformer, the phase angle will be zero. If it is a D/D, it will be zero. If it's a Y/D, or D/Y, it could be +30, -30 (usually). I have seen a few strange cases where a Y/D was +150 degrees.
Why when voltage applied to only one phase of the primary side voltage is produced in all the three phases of secondary in a transformer?
Your question doesn't describe under what circumstances the transformer is being used. Normally, a two wire (hot and ground) AC voltage can only be a single phase supply. Look up the explanation of how AC current cycles on a sinewave (60Hz is 60 sinewave cycles per second). This is also known as a single phase. Coming into a standard residential house is a three wire line with two hot wires and a ground wire. The two hot wires are out of phase with each other (opposite sinewave). A standard transformer can have multiple outputs with various/same voltage. Look up how a transformer works. Without special electronic components for each output circuit, all taps will be in phase. A transformer outfitted with the special electronic components is very expensive and not for normal everyday use.
What does each phase look like and what are they called?
each phase looks like an ocean star and if you have woken up with it you can see it shines brightly
When the label says requires 208-240V 20amps 60HZ how do you know if it is single or three phase?
Please be more specific is this a transformer or motor or something else? Did you check the spec sheet? Did you look for any markings on the package?

Information of 3 phase transformer?
Look for 3 phase vector explanation under previous xfrmrman answers. Question must be more specific.

What is the name of the white transformer that look's like an animal?
i think its Ravage..
What does Look Inside means?
Look Inside means look inside! Like LOOK INSIDE the jar... its easy!
