What are the advantages of double wound transformer over a auto transformer?
The difference between a double wound step up transformer and an auto transformer is the double wound on the step up transformer and the single wound on the auto transformer.
Principle of operation of a double wound transformer?
they are to convert power into jeremy osborne, which in turn creates an aneesh karan
Diagram of a double wound transformer?
do exist! Is there a real question about d.w.t's? On a double wound transformer, the primary winding is isolated from and secondary winding, but still use the same common core.
Why rotating magnetic field is not produced in a transformer?
In case of Alternator, the three phases (RYB) are wound on the stator in a sequential manner (R-Y-B-R-Y-B... so on) As we are aware, the three phases are electrically apart by 120deg. so that by adopting such a stator winding, a rotating magnetic field with synchronous speed (120*freq/no. of poles) is developed. Even an emf is induced in the rotor also, with similar synchronous speed, but owing to large inertia of rotor, it cannot attain synchronous speed and stays standstill.In case of transformer, the three-phase windings are wound on three limbs - on each limb LV winding is wound on the core and then HV winding is wound over the LV winding (for increased efficiency of transformer). Due to this constructional arrangement, a rotating magnetic field is not visualized in transformer, rather mutual inductance comes in to picture.
What are the three basic parts of transformer?
core - air, iron, ferrite, etc.windings - one or more coils wound around the core.bobbin - insulating structure used to hold the windings. optional, not needed in every type of transformer. in some types of transformer the windings are prewound on the bobbin then the core is inserted into the bobbin.
What are the advantages of double wound transformer over a auto transformer?
The difference between a double wound step up transformer and an auto transformer is the double wound on the step up transformer and the single wound on the auto transformer.
In a double wound transformer the secondary winding is always connected to?
To the load !
If the primary winding of a double wound transformer is supplied with the direct current its iron core will become magnetized but there will be no emf induced in the secondary winding?
BECAUSE YOU NEED AC EFFECT TO INDUCE EMF IN TO SECONDARY WINDING.OR DC PULSING.

How do you convert a 110volt turbo oven to 220volt purchased in America you live in UK?
Buy a double wound step-down transformer (230/115 volts) of he appropriate capacity (kva) . You may have to replace the plug on your oven to match the output socket of the transformer if you buy this in England. Do not buy a single wound (auto transformer) as it can be extremely dangerous if it is wrongly connected.Alwyn.
Why use a step down trans former when the lower voltage is available?
The secondary winding of a double wound transformer is 'floating' in that it is not referenced to any other part of the circuit. You choose how to reference it. You cannot accomplish this without a transformer.
What are the disadvantages of a double wound transformer?
There is no disadvantage with a current transformer -it does exactly what it's supposed to do, that is:reduce the current flowing in the primary circuit to a value that can be handled by its burden (ammeter or protective relay).electrically-isolate its secondary circuit from the primary circuit.

What are the 2 types of wound?
opened and closed wound.
How does step down transfomers work?
A transformer has two coils of wire wound round an iron core. An ac voltage on one coil produces a magnetic field in the core. The magnetic field causes a voltage to be induced in the second coil. A step-down transformer has fewer wire turns in the second coil, therefore the output voltage is less than the input voltage.
