Summary and Conclusions
Basic building blocks of subjects like Power System Analysis and Switchgear and Protection.
Single line diagrams find applications in almost every study related to electricity transmission ranging from analysis of grids or study of all types of faults. Single line diagrams also make the study of 3 phase circuits easier.
Circuit breakers and relays. During the training I was able to see their actual implementation and structure in the substations
