Pros and Cons of Step-up Transformers

Pros and Cons of Step-up Transformers

The electrical energy sets a long way from its source to reach you. In order to decrease power losses in the transmission lines, the voltage needs to be stepped up. Here comes the role of a step up transformer which turns low voltage into high voltage. In other words, a step up transformer is a transformer in which the secondary voltage is greater than its input voltage. It reduces the output current to maintain a balance between the input and output power of the system. When active current flows through the input of the transformer, an area of alternating magnetic field is created in the iron ore, which turns on the AC current with an equal frequency in the output of the transformer. A step up transformer contains more turns of wire in the secondary coil that lifts up the received voltage in it. It generally follows the principle of electromagnetic induction.

A transformer is a vital electrical device that comes in various forms, each with its own advantages and disadvantages. Through this blog readers, will be enlightened about the advantages and disadvantages of these transformers.

Advantages of step up transformers

1. Power transmission

A step up transformer enables electricity to pass through a long distance and that too at a lower cost. It raises the voltage of the power that has to be transmitted. This helps in reducing the resistance on the line, resulting in a fewer loss. In the absence of this, the power losses in the transmission line would have been so massive that it would become difficult for electricity to reach all the places that today it does.

2. Constant working ability

Step up transformers are built with an incredible ability to work constantly without any break. Where other electrical devices need to get switched off on regular intervals for few hours for their work efficiency, step up transformers are exceptions to this case. This also shows why they are used in power distribution systems.

3. Low maintenance

Step up transformers not only work without intervals, they also come with a low maintenance facility.  The regular maintenance of these transformers covers, contacts cleaning, repairing damaged part etc which do not involve much time and money.

4. No starting time

A step up transformer has the ability to begin operations immediately after its installation. Delay occurs only during the transportation of the machine from the manufacturer to the actual location and installation.

5. Proficient

The recent technological advancements have made these transformers highly efficient that generally do not suffer from major losses.

Disadvantages of step up transformers

Nothing is flawless in this world and these transformers are also no exceptions. Let’s have a look at the disadvantages of the step up transformers.

1. Needs cooling system

As we have mentioned before, step up transformers are able to operate continuously, due to which it heats up a lot. Now that we cannot wait for it to cool down, the only option is to use a round-the-clock cooling system.

2. Size

This is probably the biggest disadvantage of the step up transformers. The size of these transformers increases with an increase in the voltage which means the higher the output, the bigger the transformer. The cooling system also puts additional weight to the transformer. Both of them contribute in making the system bulky that consumes a lot of space as well.

3. Application limitation

These transformers can only be used for increasing the alternating or AC voltages and not for DC voltages.

The usage of the step up transformers can be seen in factories and power distribution system for proper functioning. That is why it is important for you to get your transformer from a renowned step up transformer manufacturers that offers a variety of transformers to meet with your requirements.
