The magnetic leakage should be very small and designers go to some lengths to reduce it as far as possible because it causes leakage inductance, which is a bad thing. Ideally the magnetic field must be confined to the magnetic core of the transformer.
The leakage flux is the magnetic flux that escapes the armature of the transformer and thus does not provide coupling from the primary windings to the secondary windings. If not minimized it can be a significant cause of energy loss and inefficiency in Transformers.

How the voltage is induced in a single phase transformer?
The changing magnetic flux in the iron core of the transformer induces a voltage in the windings.
Why there is a phase shift of 30degree in Dyn11 3 phase transformer?
The phase shift is caused by inductance in the transformer. Any inductance from magnetic flux that fails to link both windings is called leakage flux, and the resulting inductance is called leakage inductance.
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.
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 do you mean by leakage reactance in a single phase transformer?
The leakage reactance is one of the components of the reactance in the input impedance that is there when the load impedance is purely resistive. The leakage reactance is due to flux that fails to link both the primary and the secondary windings.
What is the purpose of conducting sc and oc test of single phase transformer?
The purpose of conducting sc (short circuit) and oc (open circuit) tests on a single-phase transformer is to determine its equivalent circuit parameters, such as the winding resistance, leakage reactance, and magnetizing reactance. These tests help to evaluate the transformer's performance and efficiency under various operating conditions.
What is the current of 1MVA transformer?
This depends on the voltage, and whether it is a three phase or single phase transformer.
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'.

Would you install three-phase transformer or bank of three single phase transformer in a large power station and justify by comparing the two schemes?
A three-phase transformer bank is often used in power stations because it is easier to construct and transport very large single-phase transformers, compared with constructing and transforming an equivalent-capacity three-phase transformer.
How do you test a single phase transformer?
with an meg ohm meter
