This paper describes the development of a mathematical model for the on-line condition monitoring of electric power transmission lines (TL). It includes environmental considerations in the normal conditions of the TL operation. This mathematical model is intended to be used in the verification in real time of the operation conditions of TL among two electrics substations (SEs). Different meters are installed in the SEs synchronized by GPS from where data is acquired concerning the variables that should be monitored and it also allows the validation and training of the model. Therefore this model should assist a method that will allow for maintenance predictions, based on reliability at a low cost. It will also allow verification the result of the interventions of maintenance, checking the efficiency of this in activities such as cleaning insulators. The goal of this paper is to describe the model obtained, its validations and fitting.
