2. Selection of transformer delta / star benefit in main Grid Ans - less cost &. protection system requirements.

Question

Accepted Answer

The selection of transformer delta/star configuration in the main grid offers cost savings and simplifies the protection system requirements.

Delta/star configuration reduces the cost of the transformer as it requires fewer windings compared to a star/star configuration.
Delta/star transformers are commonly used in high-voltage transmission systems where cost optimization is crucial.
The delta configuration provides better fault tolerance and can handle unbalanced loads effectively.
Star configuration simplifies the grounding system and reduces the risk of ground faults.
The selection of delta/star configuration depends on factors such as system voltage, load characteristics, and fault protection requirements.
