Auto transformer Example 2
An example case and description for an AutoTransformer.
This example models a three-phase star connected autotransformer with delta connected tertiary windings. The tertiary winding in high power auto transformers supplies a local load or station service. The tertiary winding can connect to zigzag grounding transformer banks via a circuit breaker (BRK). The zigzag transformer is served to provide adequate protection for all connected feeders. The power system with the auto transformer is shown as follows:
