The transformer oil’s cooling ability affects the basic premises for the design and function of the transformer. Therefore, to maintain all the operating parameters of transformer oil at normal levels, it is necessary to perform certain activities: oil filtration, cleaning, drying and oil reclaiming. 7.2. ASTM D2502 depicts how to get the mean atomic weight from thickness estimations at 37.78 °C and 98.89 °C (100 °F and 210 °F). GlobeCore offers a wide range of equipment designed to deal with transformer oils. Raise in temperature decreases its viscosity and vice versa. Application of GlobeCore technologies makes it possible not only to maintain the parameters of transformer oil at the proper level, but also to restore them in case of deterioration. viscosity is a parameter that influences warm exchange as oil normally courses in little transformers and as it circles by drawing in huge transformers. Obviously resistance to flow of transformer oil means obstruction of convection circulation of oil inside the transformer. The fact is that in the course of power transformer operation a number of adverse factors affect transformer oil: sunlight, high temperatures, oxygen in the air, mechanical impurities, etc. We also use third-party cookies that help us analyze and understand how you use this website. Protecting oils assume a critical job in power supply. Your email address will not be published. As you can see, the list of tasks is rather large, which poses certain demands to the properties of transformer oil. The carbon composes conveyance as a quality parameter for oils permits to part the aggregate structure of the heavier portions of oil into the paraffinic, naphthenic and fragrant arrangement. Viscosity of Transformer Oil. Oldenburg-Eversten, Deutschland, 26131.

The respective increase or decrease are detrimental to the transformer ADVANTAGE HYVOLT II is an electrical insulating naphthenic oil that meets the ASTM D-3487 specification for inhibited oils. The lower the viscosity, the easier the oil can be pumped or can circulate freely throughout the transformer for improved heat transfer and This particular grade has a low pour point and low viscosity at very low temperatures and excellent oxidation stability. Out of these cookies, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. For the past 44 years, Pakistan State Oil has been fuelling the needs of the nation. The classification and acknowledgment of the viscosity of these kinds of oils is vital, mainly in terms of production control and quality. The estimation of viscosity, in this way, will dependably remain an essential working parameter while picking an oil for your electric power gadgets, for example, transformers. You also have the option to opt-out of these cookies. Testing. But opting out of some of these cookies may have an effect on your browsing experience. Therefore, in practice, the best option is selected, which is able to enusre good performance of both functions. Its very low pour point, excellent electrical properties and high level of oxidation stability makes ADVANTAGE HYVOLT II ideal for the demanding requirements of today’s leading transformer manufacturers. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. Transformer Oil Cooling 9 S11 Viscosity !Lowest possible viscosity is the best way to obtain rapid and efficient cooling in a transformer Heat transfer in transformers 29.09.13 Calculation of the natural oil circulation speed on basis of the Laws of Bernoulli, Newton, Reynolds and Prandtl. Always remove oil with soap and water or skin cleaning agent, never use organic solvents. Process oils are likewise utilized in a few fields. If its viscosity is low, its performance will be better. ), even if it is not listed in the directory. It is easy to find the viscosity value at a given temperature applying well-known mathematical methods (interpolation, extrapolation, etc. To ensure reliable operation of your oil-filled equipment, simply contact our specialists and use their help to choose a plant with the required performance. Talk with an Expert Determination of relative viscosity of transformer oil is carried out by means of a special device – Engler viscometer. Hydrotreating limits unwanted segments, for example, sulfur, nitrogen, and aromatics. Resistance to flow of transformer oil means obstruction of convection circulation of oil inside the transformer. Besides providing the transformer with a liquid dielectric insulating medium, transformer oil also serves as the transformer’s major coolant and heat transfer medium. Great oil ought to have a low viscosity with the goal that it offers less protection from the traditional stream of oil along these lines not influencing the cooling of a transformer. Extremely hydrotreated oils can fill an assortment of need: Nypar 315 and Nyflex 3150 are process oils. Then, it is crucial to decrease the viscosity of the aged oil. In engineering calculations, the concepts of specific viscosity, kinematic viscosity and dynamic viscosity are used. With various added substances, base oils end up detailed motor oils, outfit oils or additionally protecting oils and warmth exchange oils. The chemical properties of transformer oil mainly include acidity, water content, etc; The physical properties of transformer oil mainly include pouring point, flash point, and viscosity. Dissolved gas analysis. Save my name, email, and website in this browser for the next time I comment. Testing of transformer oil is mandatory in yearly once for its maintenance. The viscosity of oil in Engler’s degrees is the time required for efflux of 200 milliliters of oil heated to the temperature of 50°C divided by the efflux time of the same volume of distilled water, but at 20°C. It is used as electrical insulation material, for heat dissipation and arc-extinguishing, as well as the medium protecting solid insulation from air and moisture. It consists of brass and metal vessels, a calibrated tube, cork and register pins. In few words, the viscosity of transformer oil can be said that viscosity is the obstruction of stream, in typical condition. So Viscosity of the transformer oil should be very less.
