Title: Optimizing Transformer Insulation: Advancements in Synthetic Ester- Based Fluids and Monitoring Techniques.

Abstract

Transformers are vital for ensuring reliable electric power supply, relying on effective insulation for safe operation. While mineral oil has been a common insulating fluid, researchers are increasingly investigating ester fluids due to their potential advantages. It is essential to understand ester fluids' properties for optimizing performance characteristics and design of transformer insulation systems. The electrical performance of thermally aged synthetic ester based insulating liquid has been evaluated considering the corona inception voltage measured using ultra-high frequency (UHF) technique and fluorescent fiber. ANN based fuzzy monitoring tool is developed using spectral data of fluorescent fiber signal and UHF signal as inputs and the output of the technique provides the level of deterioration of insulation structure. The predictive accuracy of life of transformer insulation estimated using ANN is discussed.
