Oil Testing Kits Dealers in Worli, Mumbai

Transformer Oil or Dielectric Insulation Oil and other oils required for electrical machinery and installations can be manufactured using hydro finished base oils of group II +. The base stocks are selected based on viscosity requirements of the user. In colder countries pour point is also a critical property for base oil selection. Transformer Oil (TO) be used for filling the transformer with a primary objective of providing electrical insulation between the primary and secondary coils. Dissipation of heat generated during the process is also an important function. Electrical insulation is favored by high viscosity and heat dissipation is favored by low viscosity and circulation of fluid. Base oil viscosity at a compromise level is selected. Viscosity ranges for base oil slightly defer country to country, generally in the range of 10 to 40 cst. at 400 Degree C. During the service temperature of oil rises to about 60-800 Degree C. Viscosity of oil decreases due to temperature rise. Transformer has large extended surfaces exposed to atmosphere. The oil circulates through these tubes and dissipates heat into the atmosphere.
