ABSTRACT

This The paper presents the development of three-dimensional models for the study of the electric field intensity and the potential distribution in insulators strings of an electrical system using the finite element method, and through a multiphysics platform is performed the resolution of physical systems, modelling and simulations. The design of models allows the calculation and simulation of the potential distribution and electric field intensity on insulators under different conditions of operation by enabling the analysis of the behavior against variations in conditions and factors involved in its functioning, as well as the evaluation of strategies for the mitigation of its consequences. In many high voltage applications corona discharge is seen as an unwanted side effect. Corona discharge from high voltage electric power transmission lines constitutes an economically significant waste of power for utilities. This analysis allows predicting possible future outputs of service of power lines due to failures of isolation and thus anticipating and scheduling preventive solutions.
