O principal indicador utilizado para avaliar o estado da isolação sólida em equipamentos de potência atualmente é o grau de polimerização (GP), medido por um ensaio que necessita de uma amostra de papel da parte ativa. Sendo este um ensaio invasivo, outros subprodutos do envelhecimento são utilizados para estimar o GP, como o 2-fal. Este trabalho apresenta um estudo sistemático onde técnicas de machine learning são utilizadas para estimar o GP a partir do 2-fal, da relação CO2/CO e de outros indicadores. Os resultados são promissores, indicando que 2-fal, CO2/CO, a fórmula de Chendong e a potência do equipamento podem ser utilizados em conjunto para melhor previsão do valor atual do GP do papel, logo, da sua vida útil.The main indicator use...
