Power utilities use high-voltage single-phase generators and then use transformers to develop three-phase distribution.

Question

Quizplus · Accepted Answer

Power utilities typically use three-phase generators directly because three-phase power systems are more efficient for large-scale electricity distribution. Transformers are then used to step down the voltage for various distribution needs, but the generation is inherently three-phase due to its advantages in power transmission and motor applications.
