Microprocessor protection relays. Device, problems, prospects

The book discusses the device and principle of the operation of microprocessor devices of relay protection (MURZ) on the examples of specific types of modern Murz leading world manufacturers. To facilitate the understanding of the text with energetics working with Murz, but not experts in the field of electronics, a detailed description of the MURZ elemental base, devices and principles of transistors, thyristors, optocouplers, relays are given.
The specific problems of the reliability of individual functional nodes of Murz are considered, as well as issues relating to the methodology for assessing the reliability and effectiveness of Murz. The issues of electromagnetic effects on Murz both natural and deliberate, cybersecurity are considered in detail.
The book is designed for engineers and technicians engaged in the operation of relay protection, and can also be useful to designers engaged in the development of Murz, teachers and students relevant specialties of medium and higher educational institutions
