Substation voltage levels are different, but there are still many similarities. First of all, understand and learn the basic principle, main structure, function, model and technical parameters of primary equipment (main transformer, short circuit breaker, disconnector, current transformer, voltage transformer, coupling capacitor, lightning arrester, power cable, bus, second-hand transformer, reactor and capacitor). Through the study of the above contents, I understand the whole process of electric energy production and the composition, model, parameters, structure and layout of substation electrical equipment, and have a complete concept of substation production process. Familiar with the main wiring mode and operation characteristics of substation, have a preliminary understanding of electrical secondary parts, relay protection and automation devices, consolidate and strengthen the professional knowledge learned, and lay a good foundation for future work.

Secondly, learn the post responsibility, safety responsibility, duty system and shift system of substation duty personnel, cultivate correct labor view, outlook on life and values, and lay an ideological and theoretical foundation for ensuring safe production in the future.
