Scott-T Connected Transformers

Applications
Power supply to two-phase systems (e.g., older industrial machinery)
Traction systems (railways with two-phase motors)
Balancing unbalanced loads
Interfacing two-phase legacy systems with modern three-phase grids
3. Basic Configuration
A Scott-T transformer uses two single-phase transformers:
Main transformer
Teaser transformer
Connection Details:
The main transformer is connected between two phases (e.g., A and C) of a three-phase system.
The teaser transformer is connected from the third phase (B) to a tap on the main transformer winding (typically at 86.6% or √3/2 of the winding).
