In general terms, what does a distribution substation do?

A distribution substation plays a crucial role in the electricity supply chain by taking power from the transmission system and distributing it to end-users. It functions as a key interface in the electrical grid, stepping down high-voltage transmission power to lower voltages suitable for consumer use.

In the context of this question, the primary responsibility of a distribution substation is to distribute electricity. It includes equipment such as transformers and switchgear that manage the flow of electrical power and ensure it reaches homes and businesses safely and efficiently. This effectively allows for the reliable delivery of electricity, maintaining the functionality of the electrical grid and serving the needs of local communities.

Understanding what distribution substations do is essential in the study of electrical systems and energy distribution, as they are integral components that facilitate the immediate supply of electricity where it is needed, unlike other options that focus on generating, storing, or pricing electricity.
