What is the viscosity chart for transformer oil used in power transformers?

The viscosity chart for transformer oil used in power transformers typically outlines the relationship between temperature and viscosity. As temperature increases, the viscosity of transformer oil decreases, allowing for better flow and heat dissipation. Commonly, transformer oils are tested at various temperatures, such as 40�C and 100�C, to determine their kinematic viscosity in centistokes (cSt). This chart is crucial for ensuring optimal performance and cooling efficiency in power transformers.
