How do you design a transformer with three phase 400v input and single phase 2000v output?

By design are you going to wind the transformer yourself? In your design you need a 5:1 ratio. On the output side of the transformer any two legs of a three phase transformer is considered single phase voltage. Good luck on your project.


What will happen if apply two phase supply to a three phase transformer?

A three phase transformer is simply three transformers so, supplying one phase to a set of three transformers will result in only one phase output. Any loads connected to that transformer that are expecting three phase power will malfunction, and could fail.AnswerA three-phase transformer is NOT 'three separate single-phase transformers', as suggested in the original answer. It is a single transformer with three primary and secondary phase-windings wound around a common three-limb ('core') or five-limb ('shell') core. If a single-phase supply was applied to one of the three primary windings, then single phase voltages would appear across each of the three secondary windings and the remaining two primary windings. These voltages would not be out of phase with each other.


What is the current of 1MVA transformer?

This depends on the voltage, and whether it is a three phase or single phase transformer.


How you differentiate between single phase and three phase transformer?

A single-phase transformer works with a single-phase supply, while a 3-phase transformer is used with a 3-phase supply. A single-phase transformer has 2 wires on the primary and secondary (ignoring taps) while a 3-phase tansformer has 3 or 4 wires on the primary and secondary.


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.

What is kva rating of single phase transformer?

This is the rated output of the transformer, obtained by multiplying the rated secondary voltage by the rated secondary current. And it's 'kV.A', not 'kva'.

This depends on the voltage, and whether it is a three phase or single phase transformer.


What is a single phase variac?

It is a variable autotransformer, a transformer with a sliding contact on the winding connected to a control knob, that allows the output voltage to be varied.


What will be the output if you apply a single phase on all three wires of supply side of a transformer?

Your question is confusing because you give absolutely no information on the transformer, such as its turns ratio, or any information about the supply voltage. Presumably, though, you are describing a three-phase transformer, as you refer to three wires? Again this is confusing, because you do not describe how you would supply single phase to 'all three wires'!


How do you convert a 3-phase system to a single phase?

By having a transformer with 3 phase input and single phase out put


Why the need of harmonics in single phase transformer?

Harmonics are really not needed in single phase transformers.


What is this system called with three single phase transformer?

Your question is rather vague. If you are asking what do you call a group of single-phase transformers, connected to supply three phase, then the answer is a 'three-phase transformer bank'.

Can transformers be connected in series?

A: Absolutely but the output for a power transformer will be less. the phases can also be out of phase on the output yielding no output at all.
