Hyvolt II meets requirements of ASTMD 3487-2009. This measurement is taken 3 to 6 times in the same sample of oil, and we take the average value of these readings. There is another key point to use transformer oil in a power transformer. in Dyne/cm or milli-Newton/meter. Transformer oils come in a wide range of types, meaning there isn’t a single chemical name for all oils. 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. Transformer Oil does mainly two tasks. Full disclaimer here. It is uninhibited electrical insulating oil made up of superior quality base oil for use as an insulating and heat transfer media in electrical Every liquid becomes more viscous if the temperature decreases. Despite the disadvantages mentioned above, paraffin-based oil is still commonly used in many countries (such as India) due to its high availability. Apar offers Transformer oils tailor made to suite the exact requirements of different types of Transformers and the latest National / International Standards like IEC 60296-2012, ASTM D 3487 - 2009 Type I & II , EN BS 60296 , BS 148 - 1998 Class I/ IA & II / IIA , DIN 57370 / VDE 7370, AS. We are a prestigious organization in the field of offering Transformer Oil to the clients. These tests will help determine if the oils are clean and will create a baseline of properties that need to be tested periodically. Good oil should have a low viscosity so that it offers less resistance to the conventional flow of oil thereby not affecting the cooling of a transformer. Transformer oil is also used to preserve the transformer’s core and windings – as these are fully immersed inside the oil. 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 So resistivity of the insulating oil must be high at room temperature and also it should have good value at high temperature as well.That is why specific resistance or resistivity of transformer oil should get measured at 27oC as well as 90oC. It is manufactured through special refining process selecting optimum types of hydrocarbons so that finished transformer oil provides longer service life, It does not contain Poly-Chlorinated Bi-phenyis (PCBs). The power transformer protection as a whole and the utilization of the below presented protection devices are not discussed here.. 1. It must be leveled and fire-resistant. This Transformer Oil is used to enhance the performance of the transformers. There are two main types of transformer oil used in transformers: Naphtha oil is more easily oxidized than paraffin oil. Acidity accelerates the oxidation process in the oil. A PCB oil is only a hazardous materials subject to USDOT regulations in transportation if there is 1 lb or greater of PCBs in a single packaging. The main advantage of using MIDEL transformer oils over mineral oil is their far greater fire safety. Chemical name or formula name of usually using in transformer is DIFLORO DICHLORO ETHYL BENZENE . The amount of dissolved gas in transformer oil can be found using a dissolved gas analysis (DGA) test. 2) High resistivity leading to better insulation values between windings. It is of two types: Paraffin-based transformer oil and Naphtha-based transformer oil. Although Paraffin oil has a lower oxidation rate than Naphtha oil, the oxidation product (sludge) is insoluble and precipitated at the bottom of the tank. Minimum breakdown voltage of transformer oil or dielectric strength of transformer oil at which this oil can safely be used in transformer, is considered as 30 KV. 1767.1 - 1999 and Doble's TOPS, IS 335 - 1993 and IS 12463 - 1988. © 2016 - 2021 KaaShiv InfoTech, All rights reserved. The performance characteristics of transformer insulating oil are monitored and tested at several stages during its service life. We are a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for us to earn fees by linking to Amazon.com and affiliated sites. For measuring BDV of transformer oil, portable BDV measuring kit is generally available at site. It is the minimum temperature at which oil starts to flow under standard test condition. The oil used in the transformer is a key element to check the physical condition of the unit. BDV is an important and popular test of transformer oil, as it is the primary indicator of the health of oil and it can be easily carried out at the site. A comparison between the Naphthenic and Paraffinic Transformer Oil is listed below. A low value of BDV indicates presence of moisture content and conducting substances in the oil. We measure the water content in oil as ppm (parts per million unit). Concrete base. flash point of transformer oil is more than 140°(>10°). High resistive insulation is a good insulator. So we should try to keep the value of tanδ as small as possible. Most Important: Some spurious oil is being supplied by some spurious Trader in the Name of Transformer oil which looks like Transformer oil but actually this type of oil having flash point of about 100 deg C is very dangerous to public life and property. 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. If the loss angle is small, then the resistive component of the current IR is small which indicates a high resistive property of the insulating material. High Pour point does not cause any problem because of hot climate of India. Paper absorbs the maximum amount of water from oil which affects paper insulation property as well as reduced its life. This is also known as neutralization number. 2. Mineral oils have long since been recognised as a fire hazard, but MIDEL’s natural ester fluids and synthetic ester MIDEL 7131 all possess a 100% fire safety rating. Transformer oil Treatment. The Autobots (also known as Cybertrons in Japan) are the heroes … Description : Procurement Plan for Supply Transformer Oil for Phu My 1 Date Approval: 19/07/2019 Package: 1 Type: Goods Name: Supply transformer oil for Phu My 1 Price: 968.000.000 [Disclaimer: The above text is machine translated. But in reality, no insulating materials are perfect dielectric in nature. The acidity test of transformer oil can be used to measure the acidic constituents of contaminants. The power transformer protection as a whole and the utilization of the below presented protection devices are not discussed here.. 1. Paper is highly hygroscopic. The properties (or parameters) of transformer oil are: The dielectric strength of transformer oil is also known as the breakdown voltage (BDV) of transformer oil. Buchholz (Gas) Relay. See bigger list of transformer oil testing methods in the end of the article. Transformer Oil Filters Products from parker include. There are two types of Transformer Oil, Naphthenic and Paraffinic based Transformer Oils. Parker's transformer oil filters maximize the performance and service life of insulating oil by removing moisture and contaminants to increase transformer life spans and reduce transformer breakdowns. Ergon's Hyvolt II Transformer Oil is a severely hydrotreated naphthenic insulating oil that does not require carcinogenic labeling. When the oil gets deteriorated or the solid insulation gets damaged, or its quality decreases, and because of this, the efficiency of the transformer gets affected. Overheating oil will produce methane and ethylene (300 degrees F) or methane and hydrogen (1,112 degrees F). Even if the cost of testing is high, the expense should be compared to the cost of replacing a transformer and the downtime associated with losing the transformer. So taking the proper testing procedures now will save you thousands of dollars in the long run. If oil becomes acidic, the water content in the oil becomes more soluble in the oil. Hyvolt II meets requirements of ASTMD 3487-2009. Dry and clean oil gives BDV results, better than the oil with moisture content and other conducting impurities. Transformer oil is called as mineral oil which is free from FATTY acids.And the Chemical name of Transformer oil is Hydrotreated Light Nepthanic Distillate. In this mineral Oil, available in market are by the name of POWER OIL, TRANSOL, SAVITHA, APAR, GHANDHAR etc. and to provide proper insulation . Over time, the oil will degrade resulting in the potential for faults and costly repairs. The gassing rate will vary based on the loading, insulation material, and transformer design. Oil Natural Air Forced (ONAF) ONAF method is used for the cooling of the transformer of rating up to 60 Mega volts ampere.As discussed above that in ONAN method, the dissipation of heat is taking place by the convection process in which air is naturally circulated to cool down, but in this type, the forced air is used for the purpose of cooling the transformer. See bigger list of transformer oil testing methods in the end of the article. Insulating oil in an electrical power transformer is commonly known as Transformer Oil. MAIN COMPONENTS OF A POWER TRANSFORMER Figure 4.2 illustrates the outline drawing of a transformer. In this kit, oil is kept in a pot in which one pair of electrodes are fixed with a gap of 2.5 mm (in some kit it 4mm) between them. Whenever oil temperature increases to specific level, it provide signal to alarm circuit. In this mineral Oil, available in market are by the name of POWER OIL, TRANSOL, SAVITHA, APAR, GHANDHAR etc. The performance characteristics of transformer insulating oil are monitored and tested at several stages during its service life. In India, Naphthenic based Transformer oil is used in spite of its high pour point. Noticeable darkening oil indicates either contamination or that arcing is taking place. The Buchholz protection is a mechanical fault detector for electrical faults in oil-immersed transformers. 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. Acid coupled with water further decompose the oil forming more acid and water. Interfacial tension between the water and oil interface is the way to measure the attractive molecular force between water and oil. Flash point of transformer oil is the temperature at which oil gives enough vapors to produce a flammable mixture with air. So it is desirable to have a very high flash point of transformer oil. Autobots. * This is a toy-centric character list. As an insulating material is dielectric in nature the current through the insulation ideally leads the voltage by 90o. Transformer oil needs to be tested to ensure that it works for today’s standards. During oxidation, acids get formed in the oil the acids give rise to the solubility of water in the oil. This oil in your transformer acts as an insulator and a cooling agent. 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. That means at which voltage dielectric strength of transformer oil between the electrodes has been broken down. Flash point of transformer oil is the temperature at which oil gives enough vapors to produce a flammable mixture with air. It give reading directly through a sensor. But the product of oxidation – i.e. Typically a oil/water heat exchanger (radiator) is attached to the outside of the tank. Which grade of mineral oil is used in transformers as transformer oil? Includes characters named on or in official, Hasbro toy packaging. We express the acidity of oil in mg of KOH required to neutralize the acid present in a gram of oil. In the last five decades in India, there is a drastic change in production technology. There are different configurations of units, that operate with transformer oil. The transformer oil acts as a barrier between the atmospheric oxygen and the cellulose – avoiding direct contact and hence minimizing oxidation. As a result, the paper releases water and increase the water content in transformer oil. Properties of MIDEL 7131 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. Transformer oil is a mineral based oil that is commonly used in transformers for its chemical properties and dielectric strength. The mineral-based oil like transformer oil is frequently used in different types of transformers for its dielectric strength as well as electrical properties. The fluid is either: Conventional transformer oil (mineral oil), Envirotemp® FR3 fluid, or; Silicone fluid. Concrete base. What is the chemical name of transformer oil? It absorbs the excess amount of heat when the transformer is operational and keeps the transformer cool from inside. If the resistivity of the insulating oil gets decreased, the value of tan-delta increases and vice verse.
