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 synchronous reactance?
Synchronous Reactance (in a generator analysis domain) is and equivalent series per-phase inductance term (think per-phase winding resistance) and is mainly composed of the machine's per-phase leakage inductance (equivalent series inductance of primary and secondary flux leakage) and armature reaction (distortion in flux introduced by an armature current in a machine, once again on a per-phase basis; described as a series inductance). L_SyncReac=L_leakage+L_ArmatureReaction. That sort of touches the surface of synchronous reactance.
What is mutual coupling in transformer?
It stands for how does the primary and secondary winding magnetic fields connected firmly without much of leakage flux.
Does frequency effect total inductance?
Inductance is inductance, and is not a function of frequency. Frequency affects reactance, and ultimately impedance, not inductance.
What is magnetic leakage of a single phase transformer?
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.
Why flux must lag the applied voltage by 90degrees in transformers?
It's not a matter of 'must'; it's a natural phenomenon. Because of the very high inductance, the magnetising current lags the supply voltage by 90 degrees and the magnetic flux is in phase with the magnetising current.
What is the formula for inductance flux leakage?
the product of number of turns and flux through the coil ........by maherbano

Does magnetising metal accelerate rusting?
Yes
How do you measure inductance of a coil?
Type your answer here... By use an inductance meter or an inductance bridge
What is inductance comparsion bridge and its application?
It is used to measure the inductance of a coil of unknown inductance.
What is inductance measured in?
Inductance is measured in henrys.

What is the magnetising force?
its a force that moves by electric current
