Transformers have been playing a significant role in keeping our homes and industries well lit and electrical appliances functioning constantly. However, for an industry, purchasing a new transformer would imply burning a considerable hole in the pocket. Therefore, they would look forward to seeking reconditioned power transformer in event of their transformer undergoing the necessary repairs.
It would be a good option to consider repairing the transformer than purchasing a new one, as you would be able to save your precious time and money in the process.
Nonetheless, prior to venturing into the benefits offered by repairing a transformer than replacing one, let us delve into the working of a transformer.
Understanding the working of a transformer
Not all would be aware of the working of a transformer. It has been a basic transformer transmitting electrical energy from one circuit to the other. It would act in reducing the voltage of electricity that travels from power plants to homes.
Electricity would be generated in a conventional power plant with fossil fuels heat up water. It would cause steam to rise and push the generator turbines. The mechanical energy would be converted into electrical energy that travels through the wires in order to reach the transformers. At this instance, the electricity has high voltage, which has been deemed essential for it to pass through the wires from the power plants to the buildings. On the way, the electrical energy would come in contact with a series of transformers that would slowly lower the voltage until it actually reaches the level deemed safe for offices and homes. These would be known as step-down transformers.
A majority of transformers would comprise an iron core surrounded by two coils of insulated wire. The primary coil would be attached to alternating current. It would be used for producing a continuously varying magnetic field revolving around the primary coil. The varying magnetic field would produce an alternating current in the alternative coil or the secondary coil. The secondary coil would be linked to a separate electric circuit.
In most step-down transformers, the primary coil has been tightly wound as compared to the secondary coil. The secondary coil would contribute to the reduction of the voltage of electricity as and when it would be distributed.
There would also be transformers used for increasing the voltage of electricity traveling through it. These types of transformers would be popularly known as step-up transformers. In these kinds of transformers, the secondary coil would have numerous turns as compared to the primary coil.
