Prediction of remaining life of power transformers based on left truncated and right censored lifetime data
TLDR
We develop a statistical procedure, based on age-adjusted life distributions, for computing a prediction interval for remaining life for individual transformers now in service for an energy company’s fleet of high-voltage transmission and distribution transformers. Expand
