2. When you start to learn design, you can first look at the Manual of Electrical Design for Power Engineering (electrical primary part), compiled by Northwest Electric Power Design Institute, which is an essential tool for electrical primary design;
3. Let's take a look at the relevant electrical design specifications. There are many N's, such as substation design specification and distribution equipment design specification. You can look at Kamijozu first.
4. Secondly, download a list of design cases on the Internet and have a look, so that you can know which drawings to design for the next project, what to reflect on the drawings, and take a look at the specifications of the drawings and so on. The State Grid has the overall design of the substation, with a list of cases on it, which the bookstore has bought;
Finally, find a better design institute and a better master to ask more questions and practice more. I don't think you should consider the salary as soon as you start to learn design. It's ok to have a better master in a better design institute even if you don't pay for it, because in designing high-tech jobs, especially power design, as long as you learn something, you don't have to be afraid of not finding a good job.
