Ten Important Things To Consider While Purchasing Transformers

First of all, buying a transformer is not an easy task. When you buy the transformer, you need to know about it well to meet your expectations. Nowadays, power supply from power plants finds it challenging to discover an exact area for establishing a transformer. This difficulty is common in municipal areas, so you need to consider all the factors to choose a suitable place to install a transformer.

The fundamental purpose of Transformers is to decrease the power supply from higher voltage to the minimum voltage. The selection of Transformers depends upon the requirement of customers and their budgets.

Transformer manufacturers India can install Transformers quickly and efficiently. Thus, considering the area or space availability and the power supply.

If you know nothing about transformers, you need to consult with the transformer manufacturing team or transformer manufacturers India to help you get the specification of transformers you are looking to buy or which range from design-build.

You have several essential principles regarding electrical Transformers which are necessary to know before buying. 

Transformer manufacturers India opt for various sources to serve the customers, and hence they fulfill many purposes.

Ten important things to consider while purchasing transformers

Here are ten essential things you need to know about Transformer design before buying.

1. How many phases are needed?

Initially, it is essential to know or determine whether you need a single-phase or three-phase transformer. This determination is based on the equipment that you are using. 

For example, many people in several countries use single-phase transformers because it is more than enough for most small machines. In contrast, 3 phase Transformers are commonly seen in large apartments or businesses or factories or industries.

2. Which voltage are you using for the transformer?

Transformer manufacturers India design Transformers only after knowing about the input voltage and the output voltage, whereas input voltage is otherwise known as primary voltage, and the output voltage is otherwise known as secondary voltage. Determining the voltage depends upon the power supply and the voltage of the equipment.

Depending on the Incoming power supply and required output, input voltages and output voltages vary accordingly. Military ships often need an input voltage of 440 volts and an output voltage of 118 volts. 

3. What should be the frequency range?

Generally, the power supply determines the frequency of a transformer. At Times, the incoming frequency changes from the required output frequency. This variation is usually done using a frequency converter on the output of the transformer. 

For example, some countries run transformers at the frequency range of 50 Hz. When equipment imports from countries like the US, the frequency range will be 60 Hz. In situations similar to this, you will need both a frequency converter and a transformer. 

4. What should be the required kVA rating?

Transformer design plays a vital role in determining the load size and nature of the load. The primary winding or secondary windings calculate the kVA sizing of the transformer. This calculation depends upon voltage and current information. When you have determined the required maximum load, you can choose the transformer based on the determination.

5. What is the primary purpose of the transformer?

The purpose of the transformer, such as K factor, isolation, or an autotransformer, must be considered. This factor’s determination depends on how you can use a transformer and the requirements of the transformer.

6. In which environment should you use the transformer?

It becomes challenging to know where you can use a transformer. It is difficult to know whether you should use a Transformer indoors or outdoors or Whether You should use a transformer in hazardous areas or rural locations that require various specifications. 

The outdoor transformers are mostly filled with liquid, and the liquid protects the winding from the elements. Designing transformer temperature plays a significant role. First, you need to understand how ambient temperature works. This understanding assures you of the operating temperature. Then these temperatures are taken into account in the design process.

For example, hazardous areas use Transformers, but these Transformers often need to get approval from ATEX. In addition, other regulations should also be taken into consideration depending on specific needs. 

7. What are the requirements of space?

It is essential to note the physical sizes. The standard core sizes depend upon the transformer’s design. Transformer manufacturers India can design them depending on tight space requirements, thus meeting the consumer’s requirements. 

For example, it is difficult to lift heavy Transformers on a Marine or a submarine vessel. This difficulty occurs while adding special design features to ensure safe lifting. Sometimes you can even reassemble the Transformers in place. 

8. What are the approvals and standards required?

This part of understanding is also problematic when a specific industry operates on particular standards on approvals. 

For example, coastal equipment often requires exceptional standards and approvals for installing. Depending on the specific use, it includes Atkins, DNV, or Lloyds register. 

9. Which type of wire configuration is required?

Transformers have connections in different configurations to meet any requirements. Three types of connections are possible in three-phase transformer windings – delta, star, and interconnected star connections. 

The three-phase Transformer winding combination might depend on the transformer used. The combinations can be of the following types,

● Star delta

● Star star

● Delta star

● Delta delta

● Primary delta connection

● Secondary Star connection.

For example, the delta or Star connections are often standard lighting Transformers. However, when you require a neutral connection to another system, a different connection is needed.

10. What are the other things you need to think about?

It would be best if you also thought about the efficiency of the transformer, impedance, cooling methods, and power factors of the Transformers. 

Transformer manufacturers India help install any transformer, including a single-phase transformer, three-phase transformer, pole-mounted transformer, and pad-mounted transformer.

Conclusion

Thus, this article has seen the ten things you need to remember while purchasing Transformers. When you choose the perfect transformer for your company or any other purpose, you can increase the transformer’s life and efficiency by noting these factors as mentioned above.
