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
How does eddy current loss effect a transformer?
Eddy currents act to increase the temperature of a transformer's core above ambient temperature, resulting in a loss of energy through heat transfer -thus reducing its efficiency.
What is use of metering core in transformer bushing?
It is the current transformer core meant for metering.
What is the meaning of magnetic balance test?
Magnetic balance test is performed on transformer to check, whether the core and windings of the transformer is balance position or not. Magnetic Balance is a test of Critical use as it helps us to enhance the efficiency and life of transformers.
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.
What is the percentage load at which maximum efficiency occurs for the single phase transformer?
That is the maximum efficiency occurs when the copper losses are equal to the core losses of the transformer.

What will happen if transformer are connected to dc supply?
It will get core saturation
What is the condition for maximum efficiency of a 1-φ transformer?
The efficiency of a simple transformer is limited by resistive loss in the wiring, and by hysteresis (magnet related) losses in the transformer core. You may limit the resistance loss by using superconductors at very low temperatures. But not practical for most situations. (Yet!)
What is the use of core transformer?
500w iron core transformer .that kind of size
How does eddy current loss effect a transformer?
Eddy currents act to increase the temperature of a transformer's core above ambient temperature, resulting in a loss of energy through heat transfer -thus reducing its efficiency.
Is this statement true or false the maximuim efficiency of transformer is occured when iron losses is equal to full load copper losses?
Copper losses are directly related to loading of the transformer. Iron (core) losses are a result of magnetizing of the core of the transformer, and are relatively constant from no load to full load. With this in mind, it should be clear that the above statement is false. Maximum efficiency results with low core losses, and low copper losses. Copper losses cannot be helped, so it is important to minimize core losses to increase the efficiency of a transformer.AnswerYes, it is perfectly correct -well, with the proviso that transformers normally operate somewhat below full load and, so, are designed to achieve maximum efficiency somewhat below full load. A transformer's maximum efficiency does indeed occur when the copper losses and iron losses are equal. Unfortunately, the mathematical proof of this is too complicated to reproduce here, I suggest that you check out any reputable electrical engineering textbook.
What is use of metering core in transformer bushing?
It is the current transformer core meant for metering.
What will happen when the iron core of transformer is replaced by plastic?
The coupling between windings will be nearly zero, resulting in nearly zero output. In short, your transformer's not going to work.

Magnetic balance test is performed on transformer to check, whether the core and windings of the transformer is balance position or not. Magnetic Balance is a test of Critical use as it helps us to enhance the efficiency and life of transformers.

What happen if wood is used for making transformer core instead of iron?
It would not function. In general, the core must be made of a material with certain magnetic properties. Wood has none.
