“…1. Introduction: Epoxy nanocomposites have been widely explored for dielectric and insulation applications in the last few years [1][2][3]. It is not only feasible for insulation in high-voltage transmission and distribution systems but also find uses in motors, transformers and other high-performance applications [4][5][6].…”

Epoxy/silica micro and nanocomposites are prepared and subjected to multiple accelerated stresses along with neat epoxy for 9000 h in a specially fabricated chamber. Leakage current measurements were recorded after each weather cycle. Dielectric strength was also evaluated according to ASTM-D149 after each 1000 h ageing. In the course of ageing time, neat epoxy was found with high dielectric loss and random rise in leakage current. In the case of both micro and nanocomposites, these properties indicated improvements over neat epoxy. By applying regression technique over leakage current measurements, relatively longer service lives of epoxy composites were estimated.
