Transformer Oil consists of organic compounds namely parraffins, naphthenes, aromatics and olefins. Mineral oil is used in a variety of industrial/mechanical capacities as a non-conductive coolant or thermal fluid in electric components as it does not conduct electricity and functions to displace air and water. When theRead More An American leading oil refinery that manufacture and sells transformer mineral oil. 76 Transformer Oil 1. Standard ASTM D3238 defines how to calculate the carbon distribution and ring content of olefin-free petroleum oils from measurement of refractive index, density and molecular weight (by n-d-M method). Physical Properties. The amount of oil used in a transformer depends on the size of the transformer. 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. NYTRO Libra is an uninhibited transformer oil that conforms to IEC 60296 Edition 5.0. The basic chemical structures of all the oil are more or less the same. All these compounds are hydrocarbons, so Transformer Oil is is a pure hydrocarbon mineral oil. The only differences are in their molecular structure and molecular weight. 1. Most power transformers are filled with mineral oil refined to achieve the desired electrical and chemical properties. Constituent Mass (kg/kg oil) Density of Transformer Oil at 29.5oC is 0.89g/cm3. Keywords: vegetable oil, mineral oil, power transformers, … TLV-TWA 8 hours ACGIH (1998). Numerical analysis. I guess it's a question of whether you take that over the non-conductivity.) Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. As the temperature expands, the density of the oil diminishes. Product name Transformer Oil Product number 7851 Internal identification GHS22014 1.2. It is configured as standard based on the density of mineral oil. MIDEL eN 1215. Formulas are taken from Russia's GOST R 8.610-2004. Figure 1: Mineral Oil-Based Transformer Oil System Boundaries. Once you decide to dispose of the transformer, you are no longer required to assume that it is a PCB Transformer. Mineral-oil based transformer oil is composed of the materials listed in the Table below. The calculations for the mineral oil case are matched with the manufacturing data. Unlike competitive products formulated with naphthenic mineral oils, LUMINOL TR and TRi use Petro-Canada's ultra-pure severely hydrotreated isoparaffin base oils to deliver worry-free, corrosive sulphur-free performance in your transformer. Engineering measures to reduce exposure: Mechanical ventilation and local exhaust will reduce exposure via the air. endstream endobj startxref The TXplore service can be offered for mineral oil, ester fluids and silicone. 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. 3 pounds of fluid other than mineral oil at an unknown concentration, while the transformer is in use you must assume it is a PCB Transformer, i.e., that it contains 500 ppm PCBs. Mineral insulating oil in transformers Abstract: Nearly all load bearing transformers in electric power delivery systems around the world are filled with liquid. Density of the oil (g cm −3) 0 5 10 15 20 25 30 35 1.0 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 Age of the transformer (years) Fig. Can the TXplore inspect a transformer that contains PCB contaminated oil? Mineral oil is one of those most important and widely used insulating materials. Short term value: 5 mg/m3. Due to these above mentioned negative points attached with mineral oil, its use is highly questionable in many countries. Yes. The MIDEL range of ester transformer fluids delivers an array of distinct benefits when used in a power transformer or distribution unit. The specific density of transformer oil will vary based on the manufacturer and region or location where the oil will be primarily used. [��QF�(�K�NK�WX�`[�L>2`�vD�K,� C̰!W����q�*'�-�A�[U.
