Transformers

What Is Electrical Transformer? 

​

The massive power wires that crisscross our countryside or slither unnoticed beneath city streets transmit electricity from power stations to our homes at extremely high voltages. A power line’s voltage rating can range from 300,000 to 750,000 volts, and some lines operate at much greater voltages. However, the voltages used in our homes are hundreds of times lower, ranging from 110 to 250 volts. 

​

A transformer’s operation is relatively straightforward. Electrical energy can be exchanged between circuits using mutual induction between two or more windings (also known as coils).

 

Advantages of transformer: 

​

• A transformer will increase or decrease basically AC voltage, current or independence  

• It is efficient for high-frequency range 

• It offers good mechanical strength 

• Transformer are widely used
