Three-phase auto transformers are commonly used in industrial settings to connect two different sources with different voltages.
The construction of Three Phase Auto Transformers is unique. It contains three sets of primary and secondary windings. Based on their types, they are classified into the following categories:

Wye-Delta Connection (Y-Δ)
Wye-Wye Connection (Y-Y)
Delta-Delta Connection (Δ-Δ)
Delta-Wye Connection (Δ-Y)

In essence, they are two sets of three single-phase transformers connected, with one side of each transformer connected in series with one phase of the other. They are usually used to step-up or step-down the voltage of a three-phase source, although they can also be used to provide isolation between two three-phase sources. 
Application Three Phase Auto Transformers
If your industry requires a better electrical power transmission system at an efficient rate, these devices are the best choice for sure.
Also, the following industries ...
... are using the Three Phase Auto Transformers:

Audio systems
Distribution systems
Induction motors
Railway systems 

These transformers are the best gadget to boost the voltage up so that anything the client requires to do can be done appropriately. 
Three Phase Auto Transformers provide a higher level of efficiency than single-phase transformers and are more reliable in terms of power delivery. 
Additionally, they are typically more cost-effective than other power options, providing an economical solution to power needs. 
Know the Reasons to Use Dry Transformer Types

Improved Safety

The use of Dry Transformer Types helps an organization stay away from harmful fluids and oils. Also, the chances of catching fire are less as there is no involvement of any lubricants or oils. These transformers are the most-preferred electrical gadgets among various industries because of their highest safety ratings. 

Less Environmental Impact

The functionalities of these transformers are great and they do not emit any harmful gas. The release of harmful gasses (in some failure conditions) from any oil-immersed transformer may cause certain environmental damage. The case is slightly different here. 
These types of transformers are better to use under different conditions and do not exhibit any harm to the nearby natural habitat. 

Better Maintenance

The cost of doing the maintenance is less as the Dry Transformer Types are efficient to deliver better electricity by boosting the voltage. Also, the working load upon the electrical staff won’t be that hard as each of these electrical equipment won’t require much attention frequently unless there is any appearance of the issue. 

Equipment Size Requirements and Capacity

Dry-type transformers have larger footprints. They are much greater than liquid-immersed transformers. However, the setup should consist of a larger electrical clearance for the easy passage of air so that these transformers get sufficient cooling space. 
The circulation of air allows this equipment to function properly without any throttling of heat. The size and ratings are limited for such types of transformers. 
Both liquid and dry transformers consume a lot of space but dry transformers consume a little less than the liquid type.
