Enhancement of Dielectric Properties of Echo-Friendly Cottonseed Oil-based Nanofluids for High Voltages

Abstract

This study investigates the performance of nanofluid-based vegetable oil (VO) as an advanced dielectric medium for high-voltage equipment, with a specific focus on AC breakdown voltage (AC BDV). Nanofluids, comprising carefully selected nanoparticles (including Al2O3, TiO2, Fe2O3, SiO2, and Graphene) dispersed in cottonseed oil (CSO), offer a unique opportunity to enhance the dielectric properties of insulating fluids. Through a systematic experimental approach, AC BDV tests were conducted in Khwaja Fareed UEIT High Voltage Laboratory, and the results were compared to with traditional mineral oil (MO) for high-voltage equipment’s. The findings reveal significant improvements in the AC BDV of the nanofluid, demonstrating its enhanced electrical insulation capabilities. This study displays nanofluids based on VO as a promising alternative for enhancing high-voltage equipment's electrical performance while considering the environment. Implementing nanofluids effectively improves the dielectric properties of insulating fluids, contributing to advancements in high voltage equipment technology.
