Abstract :
This paper presents an efficient monitoring methodology for polymeric insulators. The experiments allow that the correlation of internal and external temperatures of the insulators be implemented. Clean and polluted insulators were also inspected with infrared and ultraviolet cameras, and the influence of well dimensioned corona rings under polluted conditions was evaluated. The electrical behavior of the insulators and corona rings was estimated in simulations using the Finite Element Method.
