The failure rate is one of parametric indices for the power system of evaluation. It is defined as the inability of the system to perform its designated function properly without interruption over a period of time. The speed at which failure distribution systems depends on many factors, some of which are the lack of maintenance, aging, unskilled nature of government policy and technical experts. This paper focuses on the development of a generalized analysis of default rates in assessing the reliability of overhead power transmission line. Energy equipment operation experience shows that the system overhead power transmission lines (OLs) are the least reliable component.
Now, thousands of kilometers from LO in many countries through the 35 years of service boundary, hence the question about increasing the reliability OL moves to one of the first places on the agenda of electrical engineering. In addition, the LO components causing automatic cuts should be recorded separately. They include corrosion of parts of the tower, line equipment, cables and son; destruction of parts of insulators, etc. Great insulation length of transmission lines, combined with their high damageability, resulting in the need to consider the reliability of the OL in both the design phase and in the operation process
