Which of the following is one of the main functions of a substation?

The primary function of a substation is to change the voltage of electrical circuits from one level to another, a process known as voltage transformation. This is achieved using transformers, which either step up the voltage for long-distance transmission to reduce energy losses or step down the voltage for distribution to consumers. By modulating voltage levels, substations play a crucial role in ensuring efficient electricity distribution across various distances and applications.

Renewable energy transformation, electricity generation from different sources like wind, and energy storage are important topics in the energy sector but fall outside the core functions of a substation. Transforming renewable energy typically involves different systems or processes, while generating electricity from wind is specifically associated with wind turbines. Energy storage solutions, such as batteries, are also separate from the typical functions managed within a substation’s framework.
