What is the significance of transformer oil viscosity?

The significance of transformer oil viscosity lies in its impact on heat dissipation and electrical insulation. Proper viscosity ensures effective circulation of oil within the transformer, facilitating efficient cooling and preventing overheating. Additionally, optimal viscosity enhances the oil’s dielectric strength, reducing the risk of electrical breakdown. Monitoring and maintaining the correct viscosity is crucial for the reliable operation and longevity of power transformers.
