Functions of transformers


With electrical use becoming more common, transformer manufacturers are on the rise too. Transformers count as one of the commonly used electrical devices. Some people might argue otherwise, but each and every electrical device contains a transformer. If there is power flow in a device a transformer must be present. Its function in the device might be lowering/stepping up of current, creation of induction etc. People tend to view transformers as the huge devices where connection to the power grid occurs. They are wrong since transformers exist in all forms of sizes and shapes. Microscopic transformers have been created too. At no time will transformer use cease, unless electricians come up with a more superior device compared to the transformer. Major functions of transformers might include.

  1. Facilitates transmission of electricity.

Electricity is transmitted through wires. Transmission wires span over long distances. The distance between the source and the end user might be thousands of miles. Though current flows very fast, stop over points for the current are important. Transformers act as the stop over points. The main importance of stop over points is easing the tension and friction in electric wires. In emergency situations it is possible to cut off electric supply to some areas, transformers allow for this too. In addition transformers store electric current. Once electricity is produced, transformers allow for its distribution to specific locations.

  1. Used for stepping voltage up and down

This is viewed as the major function of transformers. From the generation source electricity has to go through a number of processes before it reaches the end user. From the generation turbines, it is stored in transformers first. Second it is wired to step up transformers to increase its voltage so as to meet the demand. In the same station it is stepped down for connection to the transmission wires. Stepping down is important since overloading transmission wires with high voltage is dangerous.

From the transmission grid it is directed to smaller sub-stations which feed electricity to the clients. In the sub stations it is stepped up again. Before the end user is wired to the grid the voltage is stepped down. In all the numerous stepping up and down of voltage the power of electricity remains unchanged.

  1. Isolation of end users from voltage dangers

High voltage possess a lot of destructive power. Supplying electricity at high voltages to the end user is very dangerous. High voltage creates resistance and tension in wires. Thus transformers are located not far away from the end user. A single transformer can serve a number of clients.

All the above functions of the transformers are aided by one aspect of transformers. They are very flexible. Transformers can be used for both AC and DC currents. Further they are compatible with various electricity phases. The main phases are the single phase, it involves a double set of wires. The three phase system involves a pattern of four transmission wires. A transformer serves all of them using any voltage and current fed in.
