Function of no-load in transformer in a open-circuit?
To calculate the no load current from transformer & core loss is also calculated.
What is use of metering core in transformer bushing?
It is the current transformer core meant for metering.
How to calculate transformer core loss and iron loss?
there are several losses in a transformer that prevent it from attaining 100% efficiency. One is core loss, which can be divided into Hysteresis losses, Eddy currents and Magnetostriction loses. see for more details http://en.wikipedia.org/wiki/Transformer#Energy_losses
What Is a core-core type transformer?
A 'core type' transformer core is one in which the primary windings and secondary windings are placed around each of the limbs, as opposed to a 'shell type' core, in which the two windings are placed across the centre core. A core-type core is a magnetic circuit equivalent to an electric series circuit, whereas a shell-type core is equivalent to an electric parallel circuit. This is better answered with a diagram, so I suggest that you do a search on the internet.
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 use of core transformer?
500w iron core transformer .that kind of size

What is the Al value of transformer?
AL means transformer core property
How do you design the transformer?
You can construct a transformer, and it's not particularly difficult if you know what you are doing. It's not possible to give you detailed instructions without knowing what type of transformer you need, and the answer to that depends on what it's for. A transformer consists of two coils of wire, electrically insulated from each other but magnetically coupled. How the coupling is done depends mostly on the frequency of operation. For electric power ( 50 or 60 Hz ) the coupling must be very tight, so the coils are wound onto an iron core. For audio frequencies you would generally do the same, although a ferrite core is a possibility. For radio frequencies, the transformer would be wound on a ferrite core if you need tight coupling for power transfer. Otherwise it might be wound without a core (usually referred to as an air-cored transformer). Please repost the question, saying what the transformer is intended to do.
What is the basic Difference between ferrite core and normal transformer?
i think Transformer operates AC and ferrite core operates in DC
What is transformer tank?
The container the transformer core and windings are placed inside is the tank.
The leakage flux of transformer depends on?
Actually it depends on the air gap between the core and the windings of the transformer. This is the reason why stepped core is used in medium and large transformers as it decreases the air gap between the windings and the core of the transformer.
What is the purpose of transformer core?
yes core is usefull in transformer since it it increase the permeability for the flux (i..e,it offers less relucyance path thanj air ).Their by decresing the losses in the transformer.
What is the center of an electromagnet called when it is surrounded by coils of wire?
In a transformer it is known as the transformer core.
