Types of Transformers

A transformer, according to the Collins English Dictionary is a device that transfers an alternating current from one circuit to one or more other circuits, usually with a change of voltage.

For example, if you purchase a stove that was built with the wiring set to function through a 120 voltage and your home is wired only with a 240 voltage, then you will not be able to connect that stove directly into your electrical wall socket. The stove will not function.

As you can see, the stove's voltage is different from your home's voltage. Does this means therefore that you will have to return the stove to the store? No, certainly not, thanks to the invention of the transformers.

In this case in order for the stove to function, it must be plugged into a transformer. This type of transformer is called a Step Up Transformer. What it does is that as the electricity passes from the wall socket to the transformer, the voltage transformer adjusts its flow and when it reaches the stove it is ready to work through the voltage in your home.

Some homes are wired to work with both 120 and 240-voltage equipment's, but other homes are wire with either 120 or 240 voltage.

Other Types of Transformers

There are also many other types of transformers.

Two other types of transformers are Isolation Transformer and Variable Auto-Transformer.

Isolation Transformer

The Isolation Transformer works as s safety device. It does not reduce nor increase the voltage. What is does is that it helps to protect you from electrocution. It works as a buffer between you and the electricity

Variable Auto-Transformer

This type transformer is as its name suggests. You can use it for the purpose of a Step Up Transformer and a Step Down Transformer, but not at the same time though. This is especially advantageous when you have multiply voltage equipment in you home.

Transformers are manufactured in many shapes, sizes and weight. A few manufactures of transformers are GE Industrial, TEMCO and Acme Transformer.

When in the Market

It is a good idea to find out what the voltages are of any electronic product that you are considering purchasing. It is important to inquire about this in order to know whether or not you will need to connect it (product) to a transformer. Also, when you are in the market for a transformer, you can bear a few more things in mind.

• Check the usage to make sure that it will do what you want it to do. That is, it is not too high or low.
• Check the level of sound. Will the transformer be making a loud noise during its operation or no sound at all?
• Will the transformer becomes hot during operation or not?
• How much electricity will it be able to hold?

Many transformer suppliers should be able to help you in making the right choice, it just depends on what you are looking for.
