What does LT stand for in power transformer?
Transformer Inductance?
What is an example of mutual inductance?
A transformer because, to work, it must use mutual inductance between its separate windings.
What principle emf induces in secondary winding of transformer?
mutual inductance
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 main cause for the coefficient of coupling of a transformer being less than unity?
initially the induced emf i.e.,self inductance is high than mutually induced emf in the other .....so coefficient of coupling is high
What does LT stand for in power transformer?
Transformer Inductance?
What does a transformer have a high inductance?
A transformer has two coils coupled via the magnetic field, and when it has no load all you see is the inductance of the primary coil, which has to be fairly high to create the necessary amount of magnetic flux. When the transformer supplies a resistive load, the input looks much more resistive.

What principle emf induces in secondary winding of transformer?
mutual inductance

What are two types of EMF induced in a double wound transformer?
1. self- induction2. mutual- induction
What is the main cause for the coefficient of coupling of a transformer being less than unity?
initially the induced emf i.e.,self inductance is high than mutually induced emf in the other .....so coefficient of coupling is high
Why transformer core is of magnetic not of wooden?
The transformer core is ferromagnetic in order to focus and concentrate the magnetic fields generated in the windings. This improves coupling and increases inductance.
What is the meaning of mutual inductance as transformer works on the principle of mutual inductance?
Mutual inductance describes the process by which a changing current in one coil, creates a changing magnetic flux which, when it links with a second coil, induces a changing voltage into that coil.
Why the power factor of a transformer is poor at no load?
The inductance of the transformer is much higher than the resistance of the transformer, resulting in very low real power losses (in watts), but some reactive power (vars).
What is the mean of in electrical uH?
The electrical abbreviation ( UH ) is a measure of inductance , as in a ferrite transformer core , inductors , choke etc. .
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.
