The paper analyzes the technical principles of construction and the typical structure of overhead electric grids 6-20 kV. Reliability calculations were performed for 18 segments of 6-10 kV electrical grids of one of the largest electric grid companies in the European part of the country. Shown, when assessing the reliability of overhead electric grids, it is permissible to take into account only reliability parameters of electric transmission lines. It is permissible to neglect failures of other grid elements in a first approximation (power transformers, circuit breaker e.t.c.)
