What properties are described in a transformer oil properties PDF?

A transformer oil properties PDF typically describes dielectric strength, moisture tolerance, acidity, viscosity, density, flash and fire point, pour point, oxidation stability, interfacial tension, and resistivity. It may also include compatibility with insulation materials, gas generation tendency, and thermal performance data. These properties help engineers assess suitability for specific transformer designs, climates, and loading conditions. Such documents are commonly used in procurement, design validation, and maintenance planning.
