Auto Transformer
An Auto Transformer refers to a transformer that features a single winding wound around a laminated core. An autotransformer is like a two-winding transformer however contrasts in the manner the primary winding and secondary winding are interrelated. A piece of the winding is common to both the primary side and secondary sides.
An autotransformer has a single consistent winding with a tap point between the primary winding and secondary windings. The autotransformer has a clear advantage because the tap point can be changed to get the voltage you want at the output. The fact that the secondary winding is not electrically isolated from the primary is the autotransformer's primary drawback. On load condition, a piece of the load current is applied directly from the supply, and the remaining part is acquired by transformer action. An Autotransformer functions as a voltage regulator.
Applications
- Efficient, low-cost way of serving the proper voltage to motors and compressors, lathes, CNC machines, and other industrial equipment requiring a step up or down from a building’s service voltage.
- Smaller profile is often half the size of a standard two-winding transformer, allowing for discreet installation.
- Used in applications where electrical isolation is not a critical requirement, such as motor starters & boosters.
Features
- Compact Size with high power rating.
- Durable and efficient.
- Significant Affordability compared to Isolation transformers.
- Prevents Motor Damage from High starting current.
