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.

Technical systems (TS) keep on developing actively due to observation and implementation of inventive ideas of developers. New ways of TS development have been found and keep on being found in the course of technical systems evolution. One way is a gradual shift towards TS automation. The material uncovers an implicit functional reason driving the trend of automation development in both current and future technical systems. The information is intended for TRIZ-specialists interested in patterns of TS development. The material will be helpful for designers of new equipment and technologies.
