ReaxFF Simulation and Experimental Analysis of Ester Insulating Oils: Degradation Mechanisms and Performance Evolution

This research investigates the thermal and electrical decomposition processes of mixed ester, synthetic ester, and natural ester insulating oils, employing Reactive Force Field (ReaxFF) numerical analysis. The study further explores the performance evolution of these oils following thermal aging and multiple AC breakdowns, analyzing the distribution of dissolved gases.

The ReaxFF simulations provide a detailed understanding of the degradation mechanisms occurring during thermal and electrical stress, while experimental analyses validate the numerical findings and offer practical insights into the maintenance of high voltage equipment. The investigation of dissolved gas distribution in these oils enhances our comprehension of their insulation properties and their potential for gas generation, a crucial aspect for preventing equipment failure.

This comprehensive study, combining numerical modeling and experimental validation, provides valuable insights into the behavior and properties of ester insulating oils, contributing significantly to the field of high voltage insulation technology.
