Step Up Transformer Working Principle: How Step-Up Transformer Works

Electricity power plants produce electricity. This electricity needs to be transmitted to the power substation to distribute it among the home, industry, commercial, and other general purposes. For this transmission, it has needed high voltage electricity for reducing transmission losses and getting better efficiency. But the generation plants aren’t able to produce the voltage.

This lower voltage is enhanced with an electrical instrument. This instrument’s name is the Step-Up transformer. Step-Up Transformer increases transmission voltage and lowers the current supply but doesn’t create any effect on frequency and power. This article will dive right into the working principle of a step-up transformer.

How Step-Up Transformer Works

The working principle of a step-up transformer is to convert a low voltage high current to a high voltage low current. The secondary windings turn number is more than the primary windings turn number. When two phages or three phages step up transformer’s primary terminal connects with the power generation line, it creates Electromagnetic Force (EMF). By the EMF, the secondary winding terminal voltage rises.

Basic Principles of Step Up Transformer.

When the primary terminal connects whit the AC source, it produces a magnetic flux in the transformer’s windings. Then the voltage increase in the secondary terminal through the moving magnetic field. The windings turn ratio between primary and secondary are not the same. There is no physical wire connection with the primary and secondary sides.

 

How Step Up Transformer Works

A transformer works restlessly. So it has no frictional force. Its works on EMF mood. So, its performance is very high. Its works with an efficiency of 95%. There are many types of transformers depending on the different types of work.
