Reliability of digital relay protection devices. Indicators. Requirements. Evaluations

The book analyzes and systematized the requirements for the reliability of digital relay protection devices, regulated in regulatory documents. Based on the experience of certification and certification of digital devices in various organizations, proposals are given on the nomenclature of reliability indicators given under technical specifications.
The assessment methods based on statistical processing of information on the right and incorrect responses are considered in practice. Examples of estimates of the selected reliability indicators are given on the basis of information obtained from exploiting organizations using standard plans and methods of control tests on reliability.
There is statistical information on devices failures and elements used in them. Dana information about the behavior of digital relay protection devices in extreme effects.
The book is intended for specialists engaged in the development, design and operation of digital relay protection devices, and may also be useful to scientists, teachers, graduate students and students relevant disciplines of secondary and higher educational institutions
