Abstract: A synthetic evaluation model for solid insulation is developed.Identified is the age of insulation. Fuzzy theory is applied to assess the degree of ageing and whether it is normal ageing or abnormal ageing. The results show that this model is effective for recognizing the status of solid insulation.
