В рамках модели получено соотношение для временно́й зависимости функции интенсивности отказов изоляции, позволяющее проводить аналитическое описание надёжности на длительном интервале времени эксплуатации.</p></abstract><trans-abstract xml:lang="en"><p>The mathematical model of electrical insulation failure is proposed. The model is based on the superposition of uniform and exponential probability distributions. Relation for time dependence of the insulation failure rate is obtained. Application of this relation provides correct analytical description of insulation reliability on a long time interval.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>надёжность</kwd><kwd>интенсивность отказов</kwd><kwd>электрическая изоляция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reliability</kwd><kwd>failure rate</kwd><kwd>electrical insulation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гнеденко Б.В.
