The main performance of electric oil for insulation oil purifier
(2) chemical properties. The chemical properties of oil are water soluble acid base, acid value, water, active sulfur, caustic sodium test, liquid corrosion, anti foam, air release value, oxidation stability, emulsification time and so on.
The chemical properties of oil are related to the refining process, refining degree and the composition and structure of base oil. The chemical properties of oil can be changed with the influence of environment or self gasification.
(3) electrical performance. The electrical properties of oil products include breakdown voltage, dielectric loss factor, volume resistivity, gas evolution and so on. The advantages and disadvantages of the electrical properties of oil (except for gas analysis) have nothing to do with their own components, mainly from the pollution of external water and impurities, or the influence of their own oxidation products to reduce their performance. The gas evolution of oil is related to its chemical composition. In general, the same base oil has higher aromatic hydrocarbon content and better gas evolution performance.
