Project: T163700 #33110

The objective of this project is to prepare a state of the art report for a better understanding of thedegradation/deterioration of polymeric insulators as well to develop methodology for theestimation of residual life of polymeric insulators due to ageing issues. The scope of the workwill primarily be a literature review on the ageing issues of polymeric insulators, causes andeffects followed by long-term performance comparison between porcelain/ceramic andpolymeric insulators and current understanding of estimation of residual life based on acceleratedand non-accelerated aging tests.
