What are the differences between mineral oil and silicone oil in transformer applications?

The differences between mineral oil and silicone oil in transformer applications primarily lie in their thermal stability and environmental impact. Mineral oil, derived from petroleum, has a lower flash point and is more flammable, while silicone oil offers superior thermal stability and a higher flash point, making it safer in high-temperature environments. Additionally, silicone oil is less toxic and more environmentally friendly, which can be advantageous in transformer applications where leakage is a concern.
