Transformers

An electrical transformer is one of the fundamental parts for the proper functioning of electric devices. However, you can find them in a wide assortment of options like power, auto, step up, step down and many more. If you do not understand the difference between them, it can be a bit difficult to find the one that suits your application. So, here is the guide that will help you.

A transformer is a device that transfers electrical energy from one circuit to another. Core and metal coil are their two main components. The metal coil carries current, whereas the core creates the magnetic field. However, you can find them in a wide variety of options based on their ratings and function. If you plan to buy one, some factors affect the purchase, like input and output voltage, power rating, AC frequency, phase, and, more importantly, the application. Below, we will explore a few crucial details to help you understand which one is the best electrical transformer for your needs. So, read on!

Things to know about electrical transformers & their types

There are many types of electrical transformers to choose from. The purpose of purchase decides which one will work perfectly for you. For example, if you are using one just to convert the voltage, you can go for the step-up or step-down type. But to isolate different parts of a circuit, you might need an isolation transformer. Similarly, to distribute the power, you will require a distribution type. The auto variety, on the other hand, is small but efficient. They even differ based on winding material, core material, brand, coolant type and more factors. So, let us explore a few things you need to know about selecting the best and top electrical transformer.

The function of an electromagnetic transformer

Its work is to convert alternating current from one voltage to another. You can use it to step up or step down the voltage. It works on the magnetic induction principle. Its basic components are coil and core. In its simplest form, it may have two or more coils wound on a steel core. When voltage is introduced to the primary coil, it magnetises the core. Then, a voltage is induced in the secondary coil. The change of voltage, or you can say the voltage ratio depends on the turn ratio of the two coils. For example, if the number of loops in the secondary coil is more than that of the primary coil, then the voltage will be more in the secondary coil.

The characteristics & price of electric transformer

Some of the basic features of a transformer, such as the frequency of input and output, remain the same whether it is step up or step down. It works on the principle of electromagnetic induction. Most of them are a lot efficient in their performances. There are no moving parts present generally; hence no friction losses happen; however, copper and core loss may occur. Speaking of the cost, it depends upon the type you purchase. There are many kinds to pick from depending upon the application, like a step up, step down, power, cooling type, and more. Some are used in industrial applications, whereas others find their use in small electronic devices as well.

Popular transformers like GE power transformers & more

Even if you know a lot about transformers, it can be tricky to know which brand and sellers to trust. Well, some have been clearly winning people’s hearts with their performances. For example, GE is a well-known name for its different types of power transformers. They can support a wide range of voltage levels and find their application in a generation, transmission, and distribution. The product line includes various types of models as per the application. Schneider electric transformers, Basler electric transformers and Pragati current transformers are also popular if you search for reliable equipment.
