Application Of Auto Transformer
What is Auto Transformer? The Auto Transformer has a voltage winding that is shared on both sides. The term "automatic" refers to a single coil acting alone, not any type of automatic mechanism. You tap the winding along its length to provide some primary voltage across its second load. You should use the Auto Transformer in applications that need to step up or step down the three-phase line voltage.
Advantages of Auto Transformer:
1. Cheaper and more efficient
2. The leakage inductance between the primary and secondary is small, so the loss is small
3. Simple structure for OEM
4. Smaller footprint for the same VA grade
The main purpose of the Auto Transformer is to regulate the voltage of the transmission line, which can be used to convert the voltage. The Auto Transformer has only one winding and automatically adjusts the voltage according to the load. These transformers require alternating currents to operate properly and cannot operate on direct currents.
Applications of Auto Transformer include:
1. Used as a starter to provide up to 50% to 60% of full voltage to the starter of squirrel cage induction motors during starting
2. It is used to slightly boost the power distribution cable to correct the voltage drop
3. Used as a voltage regulator
4. For power transmission and distribution systems, audio systems, and railways, only as voltage converters
