Abstract :
This work quantifies the degradation of XLPE insulated distribution cables in terms of electrical breakdown voltage using a needle plane geometry and area for FTIR spectroscopy. These identified parameters can be used to estimate the remaining useful life of cables and to optimize the cable replacement schedules. Significance of parameters is determined using regression analysis and analysis of variance.
