At the heart of any substation are the transformers. These devices play a critical role in changing the voltage levels of electricity. When electricity is transmitted over long distances, it is elevated to high voltages using transmission transformers to reduce energy loss due to resistance in the wires.

Depending on the design, transformers can be classified into various categories, including power transformers, distribution transformers, and auto-transformers, each serving different voltage levels and purposes.
