What Is Step Up Transformer?

A step-up transformer is an electrical device that helps increase supply voltage during the transmission of electricity. In the electricity sector, we use various types of voltage for transmission, distribution, and other work purposes. For example, we use 230 volts in our residents, 440 volts in industry, 11kV, 33kV, volts in the transmission lines. Electricity producing plants can not generate the accurate range of volts we need in the different sectors.

So, it is very necessary to up and down the voltage for this aspect. We can change the voltage with a device or instrument. It’s called a transformer. There are many kinds of transformers; step up and step down are the main type of transformers. This blog will give a clear idea about the step-up transformers.

Understanding Step Up Transformer

Firstly, one thing needs to be clear that the transformer is not an electricity generator device. It used to change (up and down) the voltage range between the two terminals of AC primary and secondary loads.

“A step-up transformer is an electrical device that is used to converts low voltage (LV) electricity of high current to high voltage (HV) electricity of low current through the principle of EMF with sustaining the same level of current, frequency, and other objects between the primary and secondary terminals.”

The step-up transformers’ primary wings turn number is less than the secondary wings turn number. Here is opposite the step-down transformer. A comparison picture of two of the transformers is given below:

A Step-up transformer is usually used in the vast sector of electrical transmission lines and other electrical devices that need a high voltage electricity supply. It helps the transmission of electricity with proper efficiency and reduces transmission costs.
