What are the parameters of transformer oil in power transformers?

The parameters of transformer oil in power transformers include dielectric strength, moisture content, acidity, and flash point. Dielectric strength measures the oil’s ability to insulate and prevent electrical breakdown. Moisture content affects the oil’s insulating properties and can lead to degradation. Acidity indicates the presence of corrosive compounds, while flash point is critical for safety, determining the temperature at which the oil can ignite. These parameters are essential for ensuring optimal performance and longevity of power transformers.
