The ongoing pursuit of enhanced efficiency and sustainability in power transformer cooling systems has spurred extensive research into the properties performance insulating fluids. This review explores evolution technologies, focusing on traditional mineral oils emerging roles alternative fluids, such as natural synthetic esters, nanofluids. Mineral oils, though widely used, degrade over time, leading to a reduction breakdown voltage (BDV) from 46 kV 30 kV, exhibiting low fire resistance. Natural esters provide improved biodegradability, safety but have higher viscosities-potentially limiting convective cooling. Nanofluids, demonstrated BDV enhancements up 47.8%, reaching 88.7 optimised formulations, alongside increases partial discharge inception (PDIV) 20-23%. Additionally, thermal conductivity improvements 5-20% contribute heat dissipation. Moreover, it addresses challenges nanoparticle agglomeration, sedimentation, ageing, compatibility with materials. analysis provides critical insights trade-offs between technical economic feasibility. Concluding an outlook future directions, identifies key parameters across various categories, establishing roadmap for nanofluid integration existing systems.

The reliability of the electrical grid is vital to economic prosperity and quality life. Power transformers, key components transmission distribution systems, represent major capital investments. Traditionally, these machines have relied on petroleum-based mineral oil as an insulating liquid. However, with a global shift toward sustainability, renewable materials like natural esters are gaining attention due their environmental fire safety benefits. These biodegradable liquids poised replace hydrocarbon-based oils in aligning Sustainable Development Goals 7 13 by promoting clean energy climate action. Despite advantages, face challenges high-voltage applications, particularly oxidation stability issues linked fatty acid composition. Various antioxidants been explored address this, synthetic proving more effective than ones, especially under high-temperature conditions. Their superior thermal ensures that retain cooling dielectric properties, essential for transformer performance. Furthermore, integrating machine learning artificial intelligence antioxidant development monitoring presents transformative opportunity. This review provides insights into role ester-filled power equipment, supporting broader adoption contributing sustainable future.
