Composition of Transformer Oil. Insulating Oils or Transformer Oils are mineral electrical insulating oils processed from fractional distillation and treatment of crude petroleum. 4.Dissolved Gases: It is the measurement of dissolved gases produced in the oil due to the decomposition of oil. Therefore only observing the behavior of the Buchholz relay is not sufficient to judge the healthy condition of a transformer. Chemical reaction and breathing action are the cause of moisture. Transformer oil is the mineral hydrocarbon oil obtained from raw petroleum. The performance properties of transformer oil depend heavily on the quality and parameters of the raw material. The transformer core is made of cold-rolled grain-oriented steel or in short CRGO. Paraffin oil gets less oxidized than Naphtha oil. In a transformer, a high PF is an indication of significant power loss in the transformer oil, usually as a result of contaminants such as water, oxidised oil and cellulose paper degradation. It creates an acceptable level of insulation in combination with the insulating materials used in the conductors and coils. It may also be any substance in the oil that either resists or conducts electricity different - Abstract: The invention relates to a transformer oil composition comprising at least one acid interceptor. ... Transformer oil performs two important functions of insulation as well as cooling for the core and coil assembly. Naphtha Oil: Naphtha Oil is a flammable or burnable, liquid hydrocarbon mixture. Insulating oils play an important role in power supply. The need for better dielectrics and transformer oils for insulation is unequivocal. The basic chemical structures of all the oil are more or less the same. Your email address will not be published. : rs 423-7363 supplier: electrolube. Insulating Oils or Transformer Oils are mineral electrical insulating oils processed from fractional distillation and treatment of crude petroleum. By contrast, the four samples of paraffinic transformer oils have a very different distribution. DGA was first introduced for transformer oil in the year 1965 in the UK. Transformer Oil is basically an Insulating Oil. Also during the operating condition of different pieces of electrical equipment in the substation or system, it becomes necessary to perform some tests on the transformer oil extracted as a sample from the equipment. Transformer oil is used to insulate the electrical power of a transformer and used to stop the direct contact of oxygen in the transformer. United States Patent Application 20120043505 . That is the same for oil. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. Naphtha oil gets more oxidized than Paraffin oil. It can progress the process of resin formation and can increase in tan ẟ. The technique used to analyze the gases dissolved in oil by gas chromatography is known as Dissolved Gas Analysis (DGA). The main problem with this relay is that the gases only accumulate in the relay container when the rate of production of the gases is high enough and when the oil gets saturated with the gases. the oil. 7.2. After that, the DGA detects 90% of the internal transformer faults before any major problem occurs in the transformer. The base mineral oil and the inhibited transformer oils also contained a suite of steranes, similar in distribution to those in the starting crude oil. The effect of neutralization number corrosion of various parts of the transformer, insulation degradation, and lower strength of electric. There was no oil used in the earlier Transformers. In scientific terms, transformer oil is a product of crude oil refining. Your email address will not be published. 76 Transformer Oil 1. It is of two types: Paraffin-based transformer oil and Naphtha-based transformer oil. A good number of these properties are experimented upon by using the breakdown The entry into a transformer of oil of substances, such as oxygen and water, leads to its oxidation in the presence of ideal conditions. The basic chemical structures of all the oil are more or less the same. Oil has three different basic properties that identify the suitability of the oil for the purpose of insulation and cooling. 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.

Thermal degradation arcing and partial discharge are the cause of dissolved gases. It is of two types: Paraffin-based transformer oil and Naphtha-based transformer oil. This oil is mainly used in hygiene oil, cold cream, perfumes, cosmetic substance, candle, and in medical purpose. Also, it should be free from any suspended matters. To confirm these properties, the tests performed on the transformer oil can also be divided into three different categories. Always remove oil with soap and water or skin cleaning agent, never use organic solvents. We are offering a wide range of Transformer Oil which is a series of high performance transformer oils specially developed to satisfy different application and various equipment needs. Density: – The density of healthy transformer oil should be 0.89 gram per cubic centimeter at the temperature of 29.5 centigrade. has two main purposes. In India, transformer oil is tested on the basis of IS 335. These gases are also dissolved in the oil but when there is a sufficient amount of gas formed in the oil it starts accumulated in the Buchholz relay. Severely hydrotreated oils can serve as base oils, insulating (transformer) oils, or process oils. And for new treated oil that should be a minimum of 60 KV RMS. Other name: insulating oil. There are several properties of transformer oils. At last, we can conclude that the transformer oil is combined with different types of component. The absence of moisture can decrease the electric strength (BDV), and resistivity of dissipation factor. Then Buchholz relay came into use. 2.Oxidation Stability: Oxidation Stability is the chemical reaction due to the combination of lubricating oil and oxygen. So to analyze the faulty condition of the transformer it became necessary to analyze the dissolved gases in the oil. 1.Neutralization Number: Neutralization number is the number of a milligram of Potassium hydroxide to neutralize completely acids present in 1 gm of the insulating oil. Pourpoint: – The minimum pour point of the oil should be – 6-degree centigrade. It is a member of alkane series and a mixture of hydrocarbons. There are some essential tests to be performed on an insulating oil before selecting it for the purpose of insulation and coolant. Naphtha is produced from the natural gas condensates, petroleum distillate, distillation of peats and coal tars. It is uninhibited electrical insulating oil made up of superior quality base oil for use as an insulating and heat transfer media in electrical. COMPOSITION. Description. Flash point: 140-150°C . Usually the process of oil aging is inextricably linked with its oxidation. Electrical Tests: – dielectric strength, power factor, resistivity. General Composition: BASE Oil. Transformer oil can be similar to a window of a house. An Insulating Oil must have the following properties: 1) Excellent dielectric properties resulting in minimum power loss. The fraction of isolated aromatic hydrocarbon has higher conductivity than the Paraffinic and Naphthenic fraction. Transformer oil is generally a hydrocarbon and thus hydrophobic; how - ever, when the sample undergoes oxidative degradation, oxygenated species such as carboxylic acids are formed, which are hydrophilic in nature. Int. Typical additives include antioxidants (inhibitors), metal passivators and pour point depressants. heat Furthermore, transformer oil prevents direct contact of atmospheric oxygen with cellulose made paper insulation of windings, which is susceptible to oxidation. Paraffin is less soluble than Naphtha oil. Moisture or water content in transformer oil is highly undesirable as it affects the dielectric properties of the oil adversely. Viscosity: – The kinetic viscosity of the oil should be under 27 CST at 27-degree centigrade. The only differences are in their molecular structure and molecular weight. A transformer oil comprising a petroleum oil, normally subject to oxidational deterioration resulting in the formation of sludge, having in admixture therewith relatively small amounts of diphenylamine and a secondary or tertiary alkyl60 substituted cresol, the amounts of said last-mentioned agents present being sufficient at least to substantially retard sludge formation. Since the formation of different gases due to the deformation of the molecular structure of the transformer oil is quite small. The other crucial thing about this insulation oil is its capacity to not allow … Transformer Oil Usage precautions Avoid spilling. In the absence of oxidation stability, metal corrosion will minimize the life of the transformer. Transformer oil is nothing but the mineral hydrocarbon oil extracted from raw petroleum. The role of a transformer oil. Kind Code: A1 . It is therefore, important to pay close attention to oil density when filling or re-filling your electric power transformers with dielectric insulating oil. Supply Ability: 300 Ton/Tons per Day transformer oil. It is available in different Grades like EHV GR-1, EHV-GR2,depending upon the compositions & values of dielectric strength, flash point, neutrilization values as per IS: 335 The sludge of Naphtha oil does not precipitate in the bottom of the transformer and does not disturb the transformer cooling system. 3.Moisture: A small amount of water which makes something wet or moist is called moisture. This is the reason, we need to analyze the dissolved gas in the oil from time to time to monitor the condition of the transformer. Section 3: Composition / Information on Ingredients Component CASRN Concentration¹ Lubricant Base Oil (Petroleum) VARIOUS >99 Additives Proprietary <1 ¹ All concentrations are percent by weight unless ingredient is a gas. Most of the gases are easily dissolved in the oil. Ional (2,6-di-tert-butyl-4-methylphynol) is used in a fraction of monocyclic aromatic hydrocarbons isolated from a transformer oil distillate. There are mainly three types of Transformer oil in general use for the purpose. It is used in oil-filled transformers, some types of high voltage capacitors, lamp ballasts, and some types of … Some synthetic insulating oils are also available in the market but we generally avoid to use them as transformer oil. Although the oxidation rate of naphthene oil is much more than that of paraffin oil. Water Content: – The water content of transformer oil should be within 50 PPM. The paraffin and naphthene based oil are mostly used for the purpose. Physical Tests: – specific gravity, viscosity, flash point, pour point, color, interfacial tension. The transformer oil is a combination of mineral oils. The oil used in different pieces of switchgear equipment like circuit breakers, current transformers, potential transformers, etc. Powerlink Oil Refinery Ltd. All rights reserved. The transformer oil performs two very important functions. Transformer oil composition, comprising at least one acid interceptor . Paraffin: Paraffin is a colorless, odorless solid substance which can’t soluble in water and does not easily react with any reagent. IFT is the surface tension of a sample … The basic chemical structures of all the oil are more or less the same. Insulating oils for general application, which are covered by this specification, are manufactured from predominantly naphthenic base crudes. Hydrocarbon helps to derive or making petroleum for transformer oils and identified by the very low values of tan ẟ at 50 Hz and temperatures from (20-125)℃. The performance of the oil is defined by the positive and negative properties of the crude oil. They have been . help dissipates ). 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 sludge of Paraffin oil does not precipitate at the bottom of the oil tank and disturb the transformer cooling system. These are carcinogenic and highly biodegradable. We have considered the eleven most common ones. Transformer oils are mineral oils, dissolved gases, Paraffin, Naphtha, and hydrocarbon. Chemical composition of oil is quite complex. That is the reason, naphthene base oil becomes the only means for the purpose in cold climate countries. These are paraffin, naphthene, and aromatic types of mineral oil. The only differences are in their molecular structure and molecular weight. Effects of dissolved gases are partial discharge, low energy discharge, arching, and high temperature. The composition of a transformer core depends on such factors as voltage, current, and frequency. The GlobeCore CMM-R systems are designed to extend transformer service life by restoring the dielectric strength and chemical composition of dielectric insulating oil. Three of four of the samples analyzed contain n-alkanes, alkyl-cyclohexanes and bicyclanes, but no iso-alkanes, steranes or PAH. The success and correctness of detected faults in transformers led a decision to undergo a routing dissolved gas analysis of all 400 KV transformers in the year 1967 in the UK. transformer oil composition wholesale, buy transformer oil composition from 69 transformer oil composition suppliers from China. The minimum resistivity of used transformer oil should be 0.2×1012 ohm-cm 90-degree centigrade and the same should be 2.5×1012 ohm-cm at 27-degree centigrade. Packaging & Delivery. Transformer oil is nothing but the mineral hydrocarbon oil extracted from raw petroleum. The oil in the transformer can be used without replacement for the entire service life of the transformer. Among these two types of oil naphthene based oil is more preferred. The invention further relates to the use of acid interceptor in transformer oils for improving stability. The transformer oil serves as the insulating as well as the cooling medium of transformers. Transformer Oil is basically an Insulating Oil. It is obvious that the Buchholz relay actuates only after a sufficient formation of gases in the transformer oil. Appearance: – The color of the oil must be clear and transparent. The cause of neutralization in transformer oil is due to the aging of oxidation. At the very beginning of using transformer oil, the gassing problem of the oil was ignored. Fatty Acids Composition of Vegetable Oils Fourteen samples of analyzed vegetable oils were mostly produced as virgin oils with a sustentative content of monounsaturated (MUFAs) and polyunsaturated (PUFAs) fatty acids. Chemical composition of transformer oil. Packing: 170kg/drum. But in a loaded transformer, … Composition of Transformer Oil. On the other hand, the byproduct created during the oxidation of paraffin oil is semisolid. In this mineral Oil, available in market are by the name of POWER OIL, TRANSOL, SAVITHA, APAR, GHANDHAR etc. Transformer oil is used to insulate the electrical power of a transformer and used to stop the direct contact of oxygen in the transformer.
