This article describes reconstruction of relay protection and automation (RPA) systems for an autotransformer at a 220 kV substation. It provides an assessment of the RPA system today, a case for modernization, and options for equipment. The analysis entails the quantitative characteristics of the calculated protection, as well as the economic feasibility of introducing domestic microprocessor-based protection devices. The article describes the basic principles of relay protection, its functional features, and the effectiveness of modern solutions.
