Hi everyone

I’m interested in learning about electrical substation design and would like to understand where to start. I know substations are important for power distribution and transmission, but I’m not sure about the main steps involved in designing one.

Some of the things I’m curious about are:

What are the basic components used in a substation?

How do engineers decide the voltage levels and transformer ratings?

What safety and protection systems are normally included?

Are there any recommended resources or books for beginners?

If anyone here has experience with power systems or substation engineering, I’d really appreciate your guidance or suggestions.
