What are the three types of substations?
Here's a breakdown of these key types:
- Step-Up Substations:Located near power plants, they use large transformers to boost the voltage (e.g., from generator level to hundreds of thousands of volts) for efficient, long-distance transmission across the grid.
- Step-Down Substations:Found at the transmission level, these reduce very high transmission voltages to lower levels for regional distribution networks.
- Distribution Substations:These are the final link, taking medium voltage from transmission lines and stepping it down to lower voltages (like 415V or 11kV) suitable for homes, businesses, and local grids.
Other Important Types:
- Switching Substations:Control power flow and reconfigure the grid without major voltage changes, enhancing flexibility.
- Collector Substations:Gather power from renewable sources (like wind or solar farms) and prepare it for transmission.
- Mobile Substations:Portable units for emergency backup or temporary power needs.
- Underground/Indoor Substations:Compact, enclosed stations used in dense urban areas where space is limited.

How big is a 400kv substation?
Transmission and distribution voltage
The higher the voltage the substation is transforming, the larger it is. The largest transmission voltage substations (400 kV and 275 kV) are typically the size of a few football pitches.
