Transformers are vital components of electrical power systems and the choice of insulating and cooling oil can have a significant impact on their performance, safety and environmental footprint. Palm-based transformer oil (Figure 1), a biodegradable dielectric fluid, has emerged as a promising alternative to conventional mineral oil for several compelling reasons. Firstly, palm-based transformer oil offers superior fire safety, with a flash point over 280°C and a fire point exceeding 300°C, significantly higher than that of mineral oil (Mohd et al., 2021). This enhanced fire safety, reduces the risk of transformer fires, contributing to a safer electrical infrastructure.In addition, palm-based transformer oil exhibits excellent moisture tolerance and is readily biodegradable, making it an environmentally friendly option. Its high moisture tolerance ensures better performance and longevity. Furthermore, this oil can extend the lifespan of the insulating paper in transformers, enhancing reliability and reducing maintenance costs.
