摘要
This paper presented the improved failure model by experimental and analysis results on electrical breakdown characteristics of oil-paper insulation at pulsating DC voltages. The time-to-breakdown of oil-paper specimens were measured by using constant-stress tests. The improved failure model was established and calculated by the parameters of Weibull model and the improved competing risk algorithm. It optimizes the faults of traditional two-parameter Weibull distribution when both time and voltage are considered as variables in estimating the lifetime of oil-impregnated paper.
