What are GE transformer oil specifications?

GE transformer oil specifications typically include ASTM D3487 standards, which define the requirements for mineral insulating oils used in transformers. Key parameters include a minimum flash point of 140°C, a dielectric strength of at least 30 kV, and a viscosity range of 10 to 30 cSt at 40°C. Additionally, the oil must have low water content, good oxidation stability, and low pour point to ensure effective performance and longevity in transformer applications.
