Sampling elec-trical insulating oil … Specific weight of transformer oil is the ratio of its weight at 20ºC to the weight of the same volume of water at 4ºC. Mineral oil is any of various colorless, odorless, light mixtures of higher alkanes from a mineral source, particularly a distillate of petroleum, as distinct from usually edible vegetable oils.. In world markets, standard density ranges shift with oil density proportions going between (0.84-0.89) × 103 kg/m3. Nytro 4000X is an insulating oil; T110 is a base oil; Nypar 315 and Nyflex 3150 are process oils; The given samples were provided by courtesy of Nynas AB, Sweden. Formulas are taken from Russia's GOST R 8.610-2004. Crude oil or petroleum has always been the primary source of TMO. Modern power industry requires higher performance dielectric liquids. The procedure of oil collection at the transformer is called oil sam-pling. Transformer oil is used in oil-filled electrical power transformers to insulate , stop arcing and corona discharge , and to dissipate the heat of the transformer (i.e. All three MIDEL fluids are more fire-safe and eco-friendly than conventional transformer oil. %PDF-1.5 ASTM D2502 describes how to obtain the mean molecular weight from viscosity measurements at 37.78 °C and 98.89 °C (100 °F and 210 °F). The amount of oil used in a transformer depends on the size of the transformer. There are some different types of transformer insulating oil available in the market. Adjustments in the buoyancy control system are required for other density liquids. transformer. In order to manufacture the transformers according to the required performance levels (dielectric characteristics, insulation and projected lifetime), specialized constructive changes were calculated and planned in … It is used in oil-filled transformers, some types of high-voltage capacitors, fluorescent lamp ballasts, and some types of high-voltage switches and circuit breakers.Its functions are to insulate, suppress corona discharge and arcing, and to serve as a coolant. The fire point of synthetic ester fluid (316°C) is very high compared to mineral oil (170°C). Can the TXplore inspect a transformer that contains PCB contaminated oil? The density of the oil is assumed to be 0.864 kg/L. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. Physical Properties. 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). Key words: Transformer mineral oil, lifetime, degradation, arrhenius law INTRODUCTION The mineral oil [1-4], with the main roles of insulating and cooling in power transformers, is similar to the blood in human body. It has a density of around 0.8–0.87 g/cm 3. act as a coolant). %�쏢 chemical properties (aspect, colour, density, water content, acidity, discharge voltage, dissipation factor, viscosity and flash point) of mixtures between a used transformer mineral oil and a new one other of the same nature, and compatibles between them for all ratios. Transformer oil (also known as insulating oil) is a special type of oil which has excellent electrical insulating properties and is stable at high temperatures. biot on July 12, 2011. But, the simulated rated TOT is 80.6 °C and the simulated rated HST is 97 °C. 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. Compare the typical characteristics and performance of mineral oil, FR3 ® natural ester fluid, synthetic ester fluid, and silicone transformer oil.. For a more precise estimate tailored to your needs, contact us. 1.1 This specification covers unused mineral insulating oil of petroleum origin for use as an insulating and cooling medium in new and existing power and distribution electrical apparatus, such as transformers, regulators, reactors, circuit breakers, switchgear, and attendant equipment. Table 1: Mineral-Oil Based Transformer Oil Constituents. From these, one can assess the environmental influence of the entire life cycle of mineral and vegetable transformer oils. Read more about NYTRO Libra (IEC 60296, ED. Mineral oil varies in specific gravity from 0.818 to about 0.920, depending on how refined it is. act as a coolant). Due to these above mentioned negative points attached with mineral oil, its use is highly questionable in many countries. Density of Transformer Oil at 29.5oC is 0.89g/cm3. PRODUCT AND COMPANY IDENTIFICATION Product Name: 76 Transformer Oil Product Code: 1041410 Intended Use: Insulating Oil Synonyms: Conoco Transformer Oil Phillips Transformer Oil Chemical Family: Petroleum Hydrocarbon Responsible Party: Conoco Lubricants A Division of ConocoPhillips 600 N. Dairy Ashford Houston, Texas 77079-1175 Transformer oil is nothing but the mineral hydrocarbon oil extracted from raw petroleum. TLV-TWA 8 hours ACGIH (1998). It is used in oil-filled transformers, some types of high-voltage capacitors, fluorescent lamp ballasts, and some types of high-voltage switches and circuit breakers.Its functions are to insulate, suppress corona discharge and arcing, and to serve as a coolant. Insulating oils play an important role in power supply. Two of the main characteristics of transformer oil are its viscosity and density. All these compounds are hydrocarbons, so Transformer Oil is is a pure hydrocarbon mineral oil. 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. Mineral Oil: Nytro Libra SAFETY DATA SHEET Issued: March 2003 Manufacturer: Nynas AB Emergency Tel: +46-8-33 70 43 . The leakage of mineral oil transformer can post a serious threat to environment if leakage or spillage. M��P�[ �%�ý�D�JF�eP�D1&91�JAr�����9Wp MIDEL 7131. has a high fire point, significantly increasing the fire safety of your transformers and reducing the need for fire protection equipment. Transformer Oil consists of organic compounds namely parraffins, naphthenes, aromatics and olefins. The TXplore service can be offered for mineral oil, ester fluids and silicone. Density of Transformer Oil at 29.5 C is 0.89g/cm3 From Pardeep Chouhan mobile no.09855359916 So one US gallon weighs between 6.83Lbs to 7.68 Lbs... An … 0 alternative to mineral oil, silicone fluid and dry-type transformers. [��QF�(�K�NK�WX�`[�L>2`�vD�K,� C̰!W����q�*'�-�A�[U. Transformer mineral oil (TMO) is a clear liquid with an odour of petroleum. A 3D CFD COMSOL model is used to calculate the rated TOT and the rated HST for the mineral oil, Midel 7131, Midel 1204, and Midel 1215. 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. (However, mineral oil has much higher viscosity than water, which I'm not sure is what you want as it suppresses convection. It is configured as standard based on the density of mineral oil. Mineral insulating oil in transformers Abstract: Nearly all load bearing transformers in electric power delivery systems around the world are filled with liquid.
