Study Notes

Substation Functions and Types

Transmission substations: step up or step down voltage levels to facilitate long-distance transmission of electricity over high-voltage transmission lines.

Distribution Substations

Primary purpose: to step down high-voltage electricity from transmission lines to lower voltage levels suitable for local distribution and consumption.

Switching Substations

Distinguished by their ability to connect and disconnect different transmission lines, circuits, or substations to redirect power flow and maintain grid reliability.

Combination Substations

Perform multiple functions, combining transmission, distribution, and switching functions, making them versatile and efficient.

Substation Components

Transformers: step up or step down voltage levels.
Circuit breakers and switchgear: control and interrupt electrical circuits.
Busbars and connectors: facilitate electrical connections and power flow.
Surge arresters and lightning protection: protect against electrical surges and lightning strikes.
Control and automation systems: monitor and control substation operations.
