An Insulating Oil must have the following properties: 1) Excellent dielectric properties resulting in minimum power loss. According to the feverish research I did as soon as the power was returned, there is a newer, new tranformer oil and an older, new transformer oil. 2. PCBs are either oily liquids or solids that are colorless to light yellow. contamination content – oil mustn’t have any bad contaminants that may cause failures in a system; flash point – a temperature, which gives vapour. Waukesha, Wisconsin 53188-3899 USA . Oddly enough, although they’ve been around for over 130 years, finding the best kind of oil to cool electrical transformers is still the Holy Grail among engineers. For this purpose, five different sets of reactors were prepared in which four different PCB-118 concentration (1, 10, 20, and 30 mg L −1 ) and three different TO concentration (0.38, 0.76, and 1.52 g L −1 ) were applied. Transformer oil is usually a highly-refined mineral oil that is stable at normal operating temperatures. Transformer Oil is basically an Insulating Oil. But it also means that there is a great deal of legacy equipment that’s nearing end-of-life that will require hazardous waste management, as PCB contamination is particularly onerous, and the regulations surrounding its disposal are commensurately strict. At this point, it’s all beginning to sound like 1)we know the oldest stuff (with PCBs) is bad, 2) the stuff after that (naphthenic mineral oil) is pretty bad. Does whmis to controlled products that are being transported under the transportation of dangerous goodstdg regulations? What was the weather in Pretoria on 14 February 2013? At first, polychlorinated biphenyls (PCBs) were employed, since they’re nonflammable and highly nonconductive. Cooper Power Systems . If regularly conducted, oil analysis allows identification of specific fault conditions that may be developing. products). Another material that was used as transformer oil is polychlorinated biphenyls or PCBs. While these chemicals had the desired profile for insulation and heat resistance there quickly proved to be a major problem. Over time oil degrades and Transformer Oils are no exception and are especially sensitive to this. As the laws of physics would dictate, the enormous amounts of current applied to the primary coil and induced in the secondary together generate considerable amounts of heat: enough to turn both coils into useless blobs of molten copper. The mineral oil as transformer oil can generate poisonous substances due to oxidative instability. The higher flash point, the better work of transformer is; pour point – a lowest temperature, which leads to freezing of oil. The disposal and clearance after equipment failure and spillage is also a very difficult exercise. One type is those things you see atop utility poles in front of houses; they look like big tin cans with wires popping out the top. This is good in the long run. 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 Customer Service: 800 … At first, polychlorinated biphenyls (PCBs) were employed, since they’re nonflammable and highly nonconductive. This means it will form a homogenous mixture with them in any proportion; and years ago the same drums, pumps, and hoses used to deliver mineral oils were used for PCBs. Oil is basically nonconductive, so it won’t short-circuit the coils, while its very high boiling point allows it to absorb a great deal of heat, thus preventing the copper from melting. However, mineral oil is flammable and can be toxic to the environment. Polychlorinated biphenyls (PCBs) are mixtures of up to 209 individual chlorinated compounds (known as congeners). Given that rouges’ gallery of drawbacks, production of PCBs was banned in the United States in 1979.Thereby, PCBs haven’t been used in electrical transformers for 40 years, more-or-less. Contact us at (888) 681-8923. FR3 fluid is much less flammable than mineral oil; it biodegrades easily and is carbon neutral, nontoxic and non-hazardous in soil and water*—and it offers superior performance to mineral oil. It creates an acceptable level of insulation in combination with the insulating materials used in the conductors and coils. WATER CONTENT Test Method IEC 814 Water, in minute quantities, is harmful in power equipment because it is attracted to the places of greatest electrical stress and this is where it is the most dangerous. Bio-based oil does not include petroleum hydrocarbons, silicons, or halogens, it quickly biodegrades in case there is a leak or spill, and is non-toxic in nature. they are not flammable and have high electrical insulation but they are highly non-biodegradable, toxic, bioaccumulative, and cannot be safely disposed of. If a transformer were to leak mineral oil, it could easily start a fire. When did organ music become associated with baseball? KNAN/KNAF transformers uses insulating non-mineral oil that has higher fire point (>300 0 C) compared to regular mineral oils (Symbol starts with ‘O’) used on typical oil filled transformers classified as ONAN/ONAF etc. Insulating Oils or Transformer Oils are mineral electrical insulating oils processed from fractional distillation and treatment of crude petroleum. Because of its flammability, fire codes often prohibit transformers that are cooled with mineral oil from inside buildings or structures. ASTM standard D3487 “Standard Specification for Mineral Insulating Oil used in Electrical Apparatus” provides additional information about the mineral oil used in distribution transformers. It absorbs the excess amount of heat when the transformer is operational and keeps the transformer cool from inside. Oil Condition: General ‘Physicals’ Analysis. For example: If the primary coil is half the size of the secondary, the voltage appearing in the secondary will be twice larger. 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. 2) High resistivity leading to better insulation values between windings. Introduction Biotransol has been used by various transformer companies in their oil filled power transformers all over Asia and North America. It’s also highly flammable. The transformer oil performs two very important functions. Transformer oils have undergone a couple of changes since being introduced. Older transformer oil contains PCB's which are extremely toxic!! 3) exposure limit for total product as oil mist (aerosol) 5 5 10 . The fluid is readily biodegradable as per US EPA OECD 301B, environmentally friendly and non–toxic to aquatic life . They use step-down transformers, for example, to reduce voltage to the relatively safe and familiar 120/220 VAC we have in our homes. Not only are PCBs toxic, they’re also bioaccumulative. In sum, an electrical transformer consists of one wire coil encased closely to a second. Common Name: MINERAL OIL (HIGHLY REFINED) CAS Number: 8012-95-1 DOT Number: None DOT Hazard Class: None ----- HAZARD SUMMARY * Mineral Oil can affect you when breathed in. It’s also worth noting that mineral oil—the most common replacement for PCBs—might be contaminated with PCBs and thus require a more rigorous level of hazardous waste management than is common for less-toxic waste oils. Thus, there are literally millions of transformers in use across America and rest of the world. Remember when transformer oil was still full of super toxic PCB's? PCBs can affect an animal’s immune system, reproductive system, nervous system and endocrine system. This is called a “step-down transformer.”, Utilities use massive step-up transformers to increase voltage (aka tension) in order to push electricity more efficiently through long-distance transmission lines—hence the term “high tension wires.”. How much money do you start with in monopoly revolution? This means, in the event of a transformer failure due to an arc or lightning strike, there would be no pool fire (as would be the case with mineral oil). Incinerating PCBs generates such poisons as chlorinated dioxins and dibenzofurans, which are even more toxic to humans, animals, and the environment than the PCBs themselves. Conventional Transformer Oil . Transformer oil, is a very nasty substance! Get a licensed firm to test the oil for PCB's and repair or replace the transformer. Invented in the 1880’s, the job of adjusting to useable levels the thousands of volts generated by power utilities has always fallen to electrical transformers. Transformer oil quality indicators. To prevent this, the transformer encasement is filled with oil, so that both coils are effectively bathed in it. Now, with silicone oil prices nearly tripling to around $7 per quart, even its financial attractiveness has evaporated. Unfortunately, they are also toxic, bioaccumulative, not at all biodegradable, and difficult to dispose of safely. Emergency Telephone: (262) 547-1251 . Big transformers are usually connected to HV lines and they are actually the source for any magnetic fields you might be exposed to. High dielectric strength Polychlorinated biphenyls (PCBs) formerly used as transformer oil, It is toxic, bio accumulative, not flammable and at all biodegradable also difficult to dispose of safely. There are no known natural sources of PCBs. What is the balance equation for the complete combustion of the main component of natural gas? As the timeline shows, the manufacturers and major users of PCBs knew by the 1930s and 1940s that PCBs caused serious health problems in their workers, … Remember that no executives in the transformer business gave a shit until it couldn't be denied anymore? 1900 East North Street . PCBs haven’t been specified inside electrical transformers for nearly 40 years. Product Information: www.cooperpower.com . Transformer Oil also acts as insulation so that it could protect winding from direct contact with the oxygen and stop any kind of oxidation reaction. There is another key point to use transformer oil in a power transformer. Mineral oil is the most common alternative, but its insulating properties are rapidly degraded by any amount of moisture. The original transformer oils were comprised of polychlorinated biphenyls, or PCBs. Sadly, they’re also extremely toxic; they’re not biodegradable; and they’re absorbed faster than they can be metabolized (or excreted) by animals and humans. * Breathing Mineral Oil can irritate the lungs causing coughing and/or shortness of breath. Hazardous Waste Experts can help you dispose of your transformers for a very reasonable price. Adequate oil treatment and, if necessary, additional interventions, can be undertaken. Table 2 Mineral Oil 1.0 Beta Fluid 4.0 FR3 5.0 Bio-Temp 6.0 Silicone 7.0 (9) Application in LTC’s, Since most of the tap-changers were developed historically for mineral oil What is BDV Test in Transformer Oil? The intense electrical and thermal strain can catalyse or initiate undesirable changes in the properties oil which may turn it into a hazard further down the line. This is good in the obvious sense, but it also means that there’s a lot of legacy equipment in existence that’s nearing end-of-life (or languishing in junk piles) that needs to be disposed, and so doing will require careful hazardous waste removing. transformer will run a few degrees hotter. And although mineral oil is relatively more benign than PCBs, it’s nonetheless an environmental contaminant that requires careful hazardous material removal. Copyright Â© 2021 Multiply Media, LLC. The leakage of mineral oil transformer can post a serious threat to environment if leakage or spillage. Oddly enough, although they’ve been around for over 130 years, finding the best kind of oil to cool electrical transformers is still the Holy Grail among engineers. (888) 681-8923, Copyright 2012-2020 Hazardous Waste Experts All Rights Reserved, How to Choose a Dumpster Rental Company for RCRA Regulated Waste. What is Toxic Waste and How Do You Dispose of it? Thus, PCB contamination can still be an issue for transformers that are ostensibly PCB-free. There is some evidence that high ac field are bad for you. Exposure Limits: OSHA PEL ACGIH* TLV STEL. As a result, it is not surprising that PCBs … When the first or “primary” coil is fed alternating current, another alternating current is induced in the nearby “secondary” one. Polychlorinated biphenyls (PCBs) were formerly used as transformer oil, since they have high dielectric strength and are not flammable. Transformer oil analysis – basic introduction By N Robinson, WearCheck As blood tests disclose one’s state of health, so oil analyses disclose the condition of a transformer. Bio- based is a type of transformer oil which is obtained from vegetable oil feed stock. The Transformer Oil Spill Cleanup Policy will be used to provide a consistent approach for the cleanup of transformer oil spill sites. act as a coolant). In this study, possible toxicity of increasing doses of PCB-118 and transformer oil (TO) on anaerobic sludge digestion was investigated. BDV in terms of transformer oil is the abbreviation of Break Down Voltage.

Sadly, they’re also extremely toxic; they’re not biodegradable; and they’re … Fitchburg, WI 53711 Why don't libraries smell like bookstores? Within hours of the power going out, transformer oil can end up on the street, where it creates another health and environmental problem because it … Hazardous Ingredients/Identity Information . This paper reviews some of the transformer oil tests and there significance. They’re amazingly simple devices—but nonetheless require end-of-life hazardous waste management. (d) Approximate Price Comparison: The relative price of various fluids compares to Mineral Oil to a base of 1.0. types of electrical voltage transformers, switches, circuit breakers and other electrical equipment requiring a liquid insulating medium of high resistivity. But that’s only half of it. 5520 Nobel Dr., Ste #125 What kind of oil is used in electrical transformers? 76 Transformer Oil 1. TWA (mg/m. Hazardous Waste Experts When burned, they form even more toxic products, such as chlorinated dioxins and chlorinated dibenzofurans. 1. 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. It is a health issue and should not be allowed to continue to 'leak' onto the ground. If it contains polychlorinated biphenols (PCBs), yes. The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. Polychlorinated biphenyls are a man-made substance first synthesized over a century ago and found to have desirable properties that led to their widespread use. How big and how near are the questions. Based on extensive studies conducted using environmentally relevant doses, EPA found clear evidence that PCBs have significant toxic effects in animals, including non-human primates. This is called a “step-up transformer.”, Conversely, if the primary coil is twice larger than the secondary, then the voltage appearing in the secondary will be half as much. Non-Mineral oil also increases insulation life of transformer, is more environmentally friendly, is non-toxic, less flammable. composition of the oil as it exists (allowing for breakdown Problem is, each will eventually wear out and require hazardous waste disposal. There are other carcinogens, and breakdown products may be All Rights Reserved. Consider: the voltages of the two AC currents will match the sizes of the two coils in exact proportion to one other. carcinogenic. Another consideration: mineral oil is fully miscible with PCBs. You would need a thorough description of the chemical Don't fool around with this! Could it be the end of an era for silicon transformer fluids? * Mineral Oil can irritate the skin causing a rash or burning feeling on contact. Also, bio-based transformer oils … For those who don't, here's a snip: "PCB history is not pretty. The body's regulation of all of these systems is complex and interrelated. For instance, concentrations of PCBs greater than 5 parts per-million are classified as hazardous waste in California.
