This book explores a new approach to designing modern information-measurement systems for electric grid control centers. It focuses on the use of foundational structures and their components, alongside advanced diagnostic and monitoring techniques for substation electrical equipment. The author introduces innovative methods for visualizing diagnostic data, standard formats for information transmission, and regional network companies' telecommunication networks. The book also details how diagnostic services are organized, outlining the goals and objectives of the information system, along with an analysis of the economic benefits of implementing such systems in regional utility companies today. Ideal for engineers and specialists involved in the design, development, and operation of automated control systems, information technology, data transmission networks, and electrical equipment diagnostics, this work will also be valuable for postgraduate students, master's candidates, and students in related fields.
