What type of electrical configuration is used for connecting multiple transformers in a balanced manner?

The correct answer identifies the Delta-Wye connection as the preferred method for connecting multiple transformers in a balanced manner. This configuration plays a crucial role in electrical systems, particularly when managing three-phase power. In a Delta-Wye connection, one transformer is connected in a delta configuration while the other is arranged in a wye (or star) configuration.

This hybrid setup offers several advantages, including improved voltage regulation and reduced phase imbalance. The wye connection allows the possibility of neutral grounding, which can enhance safety and system stability. Additionally, this configuration helps in transforming voltage levels efficiently; the delta side can handle higher currents while the wye side is useful for distributing voltages.

Utilizing the Delta-Wye method helps balance the loading and enhances the overall reliability and performance of the electrical distribution system. It is particularly beneficial in applications where a combination of high-power delivery and controllable voltage levels is necessary.
