Transformers in High Voltage Grids and Train Systems
Transformers play a critical role in the transmission and distribution of electrical power across high voltage grids and in the efficient operation of train systems. They are essential for stepping up the voltage to transmit power over long distances with minimal losses and then stepping it down to usable levels for industrial, commercial, and residential consumption. In train systems, transformers are vital for adjusting voltage levels to meet the specific needs of traction systems and onboard power supplies.
Types of Transformers
- Power Transformers: Utilized in high voltage transmission networks to step-up or step-down voltage levels.
- Distribution Transformers: Used to lower voltage levels for end-use applications in homes and businesses.
- Traction Transformers: Specifically designed for train systems, these transformers convert electrical power from overhead lines to the appropriate voltage and current levels for train engines and onboard systems.
