Abstract :
A survey of the literature reveals that the analysis of complete data on the ageing of insulation systems yields better results than the analysis of censored data. This argues in favor of the development of a new technique to convert censored data to complete data. The authors detail a novel technique developed for such conversion. It is shown that a spline technique could be adopted to construct complete data from censored data, as the results of experiments and the constructed failure times are in agreement. Results of ageing studies have been analyzed statistically using the maximum likelihood estimation approach, and results are presented
