What Is A Auto Transformer, And How Does It Work?

A Auto Transformer is an electrical device that converts AC from one voltage to another. It works on the magnetic induction principle. It is designed to step up or step down voltages.

How Do I Choose The Right Auto Transformer?

The right Auto Transformer is necessary for better productivity. So when you buy the Auto Transformer, check the label behind it. This label gives you complete detail of specifications including, Wattage (W) or the Amperage (A) of the Auto Transformer. So check the label and choose according to your wattage need.

Can 60 Hz Auto Transformer Be Operated At 50 Hz?

The Auto Transformer 1 KVA, and larger rated at 60 Hz, should be avoided for operating the 50 Hz service. It is because of higher losses and resultant heat rise. But if we reverse this, 50 Hz Auto Transformer will perform on 60 Hz service.
