What is the role of a transformer in a distribution system?

A transformer's primary role in a distribution system is to modify voltage levels to ensure electricity is delivered efficiently and safely. This includes both reducing and increasing voltage, depending on the requirements of the electrical system and the application.

Transformers are used to step down voltage from high transmission levels to lower levels suitable for use in residential and commercial applications. Conversely, they can step up voltage for transmission over long distances, minimizing losses associated with high currents. By adjusting voltage levels appropriately, transformers help maintain the efficiency of power delivery while adhering to safety standards and operational requirements.

This dual functionality of transformers encapsulates their critical place in the electrical distribution network, enabling the reliable transport of electricity across various distances and use cases.
