Question

describe the structure of step up transformer

Answer 1

A step-up transformer is the direct opposite of a step-down transformer. There are many turns on the secondary winding than in the primary winding in the step-up transformers. Thus, the voltage supplied in the secondary transformer is greater than the one supplied across the primary winding. Because of the principle of conservation of energy, the transformer converts low voltage, high-current to high voltage-low current. In other words, the voltage has been stepped up.

You can find step-up transformers located near power plants that are designed to operate megawatts of power. Apart from the power plants, step-up transformers can also be used for local and smaller applications such as x-ray machine which requires about 50,000 volts to work. Even a micro-wave oven requires a small step-up transformer to operate.

Tip: The type of metal winding used is one of the considerations used in determining the efficiency of transformers. Copper coils are more efficient than many other coil metal choices such as aluminum. However, copper windings tend to cost more, but you can expect to save the initial cost over time as the efficiency of the material will save on electrical cost.

Answer 2

consists of a soft iron core with two coils of insulated wire wrap around it separately. Each coil has a different number turns or loops. The secondary coil is where an alternating potential is induced.
