Physical properties of transformer oil
Appearance color, transparency, and density of transformer oil
Mainly based on visual observation to determine the depth of oil color and the transparency of oil quality. Transformer oil is generally pale yellow or colorless. The lighter the color, the better its refinement level. The darker the color of the oil, the more non hydrocarbon compounds it contains.
The mass of oil per unit volume is called oil density. The density of oil is related to temperature, and it will change at different temperatures; When oil is heated, its volume expands and its density decreases, so the density measured at high temperatures is smaller than that measured at low temperatures. For the purpose of comparison, the density of general oil products is often expressed as the density at a specified temperature. In China, the standard density is defined as the density of petroleum and petroleum products at a standard temperature of 20 ℃.
Viscosity, viscosity temperature characteristics, and viscosity index
The property of internal frictional resistance between oil molecules when a liquid undergoes relative laminar motion under external force
