In a delta connected power system, how are transformers connected?

Transformers in a delta connected power system are connected in a triangular phase relationship. This means that each transformer is connected at its primary and secondary windings to form a closed loop or triangle. This configuration allows for three-phase power to be distributed effectively, supporting balanced loads and providing certain advantages, such as the ability to continue operating even if one transformer in the system fails.

This arrangement also helps in managing phase shifts and reducing the neutral current, which can enhance overall system efficiency. Importantly, the balanced nature of a delta connection can help mitigate issues related to harmonics and voltage drops across the system, making it a favorable choice for certain applications in power distribution.
