How many different types of substations are there?

Substations are categorized by their place in the electrical system and the voltage transformations they perform. There are four main types: - Generation substations, located at the power plant, that step up voltage for efficient transmission. - Transmission substations, which manage high-voltage lines in the transmission network and route power between areas (often handling some switching and transformation between high-voltage levels). - Subtransmission substations, situated between transmission and distribution, stepping voltage down toward distribution levels for the feeders. - Distribution substations, which reduce voltage to the distribution level used by customers and may supply multiple feeders. Because these four distinct roles cover the typical stages from generation to end use, the total number of substantiation types is four.

Substations are categorized by their place in the electrical system and the voltage transformations they perform. There are four main types:

  • Generation substations, located at the power plant, that step up voltage for efficient transmission.

  • Transmission substations, which manage high-voltage lines in the transmission network and route power between areas (often handling some switching and transformation between high-voltage levels).

  • Subtransmission substations, situated between transmission and distribution, stepping voltage down toward distribution levels for the feeders.

  • Distribution substations, which reduce voltage to the distribution level used by customers and may supply multiple feeders.

Because these four distinct roles cover the typical stages from generation to end use, the total number of substantiation types is four.
