This study explores the production and characterization of green transformer oil derived from Jatropha Curcas seeds. As the demand for eco-friendly and sustainable alternatives to conventional transformer oils grows, Jatropha Curcas seed oil emerges as a promising candidate. The production process involves extraction, purification, and refining steps to transform Jatropha Curcas seed oil into a high-performance, biobased transformer oil. Comprehensive characterization techniques, including physicochemical, thermal, and electrical analyses, provide insights into the oil's suitability for electrical insulation applications. The results highlight the potential of Jatropha Curcas seed oil as a sustainable and environmentally friendly alternative for transformer oil applications.
