Single Phase Single Winding: The transformer has one primary winding and one secondary winding, suitable for single-phase power sources or loads.

Single Phase Two Windings: The transformer has one primary winding and two secondary windings, commonly used when different voltage outputs are needed.

Three Phase Three Windings: The transformer has three primary windings and three secondary windings, suitable for three-phase power sources and loads.

Autotransformer: Also known as an auto-transformer, it shares a portion of the winding, used for applications that require different voltage ratios or voltage adjustments.

Star Connection (Y Connection): The starting points of the output windings are connected together, with the other ends connected to different phases. Suitable for three-phase systems.

Delta Connection (Δ Connection): The output windings are connected in a closed loop triangle. Also suitable for three-phase systems.

Zigzag Connection: A special three-phase connection used to reduce harmonic currents caused by load imbalances.

Two Winding Transformer: It has two separate primary and secondary windings, suitable for special applications such as isolation transformers and phase-shifting transformers.

Each winding configuration has its own applicable scenarios and specific purposes. Choosing the right winding configuration can meet different power requirements and system demands.
