Also, natural ester oil transformer designs are more insulation intensive as the electrical stresses are present in the paper as opposed to mineral oil where the stresses are in the oil. From these, one can assess the environmental influence of the entire life cycle of mineral and vegetable transformer oils. The average density of the fluid is assumed to be 0.9565 kg/L. Store under recommended Engineering measures to reduce exposure: Mechanical ventilation and local exhaust will reduce exposure via the air. Crude oil or petroleum has always been the primary source of TMO. A significant portion of the Oxygen is from atmosphere entering through the defects. If the oil is heated, its specific weight decreases, and vise versa when the oil is cold. As the temperature expands, the density of the oil diminishes. TLV-TWA 8 hours ACGIH (1998). found that the surface charge density located at the oil/ pressboard interface in a time unit increases if the value of the real part of relative permittivity increases, respectively if the oil’s resistivity decreases.

Higher viscosity may mean better dielectric strength, but may reduce the ability of the oil to transfer heat and cool the transformer. Mineral oil-filled distribution transformer as one of the main part of electrical supply system (on photo: A distribution transformer serving a hotel in Saigon by Marcelino Cagampang via Flickr) Although the insulating oil is a flammable liquid , the reliability of the oil-immersed transformer has been proven over many years on supply systems where security of supply is of the utmost importance. The IEEE limits are split into categories for <69kV, 69–230kV and >230kV. Oil is used to cool the transformer, because it also provides part of the electrical insulationbetween internal live parts, transformer oil must remain stable at high temperatures for an extended period. Transformer Oil consists of organic compounds namely parraffins, naphthenes, aromatics and olefins. The only differences are in their molecular structure and molecular weight. The liquid functions both as an electrical insulation and as a heat transfer fluid. All three MIDEL fluids are more fire-safe and eco-friendly than conventional transformer oil. Mineral oil varies in specific gravity from 0.818 to about 0.920, depending on how refined it is.
