What is the density of transformer mineral oil?

The density of transformer mineral oil typically ranges from 0.86 to 0.90 grams per cubic centimeter (g/cm³) at 15°C. It’s crucial to consider that variations can occur based on the specific formulation and additives used. Understanding the density of transformer mineral oil is essential for applications in electrical insulation and cooling systems in transformers, ensuring proper functionality and efficiency. Proper maintenance, including regular testing for density, can help in monitoring the oil’s condition and performance. Remember that factors like temperature can slightly affect density measurements, so it’s always best to refer to the manufacturer’s specifications for precise values.
