Three Phase Transformers have three windings. If connected in Delta, it will have R Y B phase winding, voltage between RY, YB and BR. Phase voltage and line voltage are same.
If connected in Star, there will be a neutral as well with RYB. Line voltage and Phase voltage are different. Line voltage = 1.73 x Phase voltage.

∙ 10y agoThere is no such thing as a 3-phase transformer.
A 3-phase transformer is simply three transformers. You can connect the primaries in wye or delta, and you can connect the secondaries in wye or delta. It all depends on the application.
AnswerOf course there is such a thing as a 'three-phase transformer'! They are widely-used throughout the electrical transmission and distribution systems.What the first answer is describing is a 'three-phase transformer bank', comprising three, separate, but identical, single-phase transformers, connected to supply a three-phase load.
In distribution systems, three-phase transformer banks seem to be more common in North America than they are, for example, in the UK and Europe where three-phase transformers are the norm
A three-phase transformer consists of three primary-windings and three-secondary windings, installed on the three limbs of a common silicon-steel core, enclosed within a steel tank, which is normally filled with a mineral oil to provided both insulation and cooling.
The principle of operation of a three-phase transformer is too complicated to describe in this forum -better to do some research in a library or on line.

The basic function of a transformer is to change?
The basic function of a transformer is to change voltage levels.
Bil of power transformer?
B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
What is the basic Difference between ferrite core and normal transformer?
i think Transformer operates AC and ferrite core operates in DC
How you using ref relay in transformer?
an REF relay (restricted earth fault) is used to provide ground fault protection for a transformer. Its' operation is limited by CTs starred towards the transformer (usually on the transformer bushings or in breakers used to isolate the transformer), so it will only operate for transformer related faults. Because of this, it can be set to operate very quickly.
What is advantages-of-parallel operation of transformer?
It enables an existing transformer to be upgraded to meet an increase in load, without having to remove that transformer and replace it with a 'larger' (expressed in volt amperes) one. It provides an useful way of using up a stock of smaller transformers.
The basic function of a transformer is to change?
The basic function of a transformer is to change voltage levels.
Why series operation of transformer is not prefered?
current increase in series operatio and transformer will b damaged
Bil of power transformer?
B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
Why do you get a typical sound when the transformer is put into operation?
vibration of the transformer's laminated core in response to the AC magnetic field.
What is the operation of a transformer?
A transformer is a static device which is used to step up or step down the voltage in a powered circuit.
What the effect of switch on the no load transformer?
specially for high voltage operation
What are the condition for transformer parallel operation?
CONDITIONS REQUIRED FOR TRANSFORMER PARALLEL operation are.. 1. Voltage turn ratio. 2. phase sequence 3. Impedence should be same 4. polarity Hitesh
Operation of a transformer?
Transforming a signal without changing its frequency.(amplitude can be changed)
What are the basic cost of power transformer?
I have a project now, a 6 MVA 13.8KV/6.6KV transformer costs about $16,000.
What is the purpose of transforms?
A transformer is used to step up or step down a Voltage supply.
Does a basic transfomer in its normal operation use step up voltage step down voltage step up current or all?
A transformer has a primary and a secondary side. There is a ratio of windings from one side to the other that dictates whether it is a step up or step down transformer. The transformer is usually marked as to the input and output specifications. The current is directly proportional to voltage. If you had a transformer that was a step up from primary to secondary, it would be step down from secondary to primary.
How do you determine the proper cable for 240V 3phase 15hp induction motor for a distance of 1000 ft?
This wouldn't be on a farm would it? 1000' line would need it's own utility pole, and transformer.
