Three Phase Transformers (also known as three-phase power transformers) are devices designed to step up or step down voltage in three-phase electrical systems operating at 60 Hz. Commonly used in industrial, commercial, and utility applications, they provide efficient energy distribution for large machinery, equipment, and facilities. These transformers are essential for ensuring stable, reliable power in three-phase networks.
