In a stage of development of the project and during the exploitation of transmission line (TL), the specialists have to solve one of the most complicated problems – insulation failures flashover rate (IFFR). The main indicator of the IFFR of TL is the minimization of the probability of outages, which is irreversible destructions of the isolating TL designs. When using valid normative documents, for an assessment of IFFR, it is necessary to use the data of the designs of a standard type with typical geometrical parameters of lines. For atypical constructions of TL towers, this method is not appropriate. The methodology of establishment of IFFR of TL metal construction offered in this research makes the procedure of designing metal constructions easier, including also atypical TL tower constructions due to the synthesis of computer modelling included in the methodology.
