Modine (CIS) designs and manufactures transformer type BETA/CETA and ALFA oil coolers for oil insulated power transformers and reactors. The condition of oil defines transformer reliability and continuous power supply to the clients. Factors Affecting The Quality Of The Oil : The quality of the insulating oil can be determined by considering the factors like heat transfer, breakdown voltage, electric charging ability etc. Heat transfer is the key function to be performed by the transformer oil as the power transformers broadly suffer from thermal heating. 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. Since the oil is in constant contact with components it is therefore susceptible to chemical interaction. So Transformer oil and winding paper insulation starts decomposing and various gases like Methane, Ethane, Ethylene, Acetylene, Hydrozen etc. The following information and clauses concerning transformer bunds is extracted from BS EN 61936-1 : 2010. Transformer oil can be similar to a window of a house. The ability of the oil to transfer the heat can be analyzed by studying the variations in the viscosity of the transformer oil in accordance with variations in temperature. Without the use of transformers, the power supply network cannot be operated as much effectively. When a transformer uses the arrester, the arrester is dipped in the insulating oil of the transformer. Hence the maintenance of power transformers also have become more important. In this article we will look at the process of transformer oil transfer. The breakdown voltage of mineral oil alone was an average value. Transformer oil filtration equipment FLOWOIL enables to pump transformer oil from and into transformer tanks, oil storage tanks and other types of vessels. But this process leads to accumulation of charges around the surface of the oil and creates partial discharge which further cause breakdown of the transformer. 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 . Why is transformer oil purification essential? Oil filled transformer is to place the body consisting of iron core and winding in a fuel tank filled with transformer oil. Transformer oil testing is one of the important parts of a power transformer.This test will be performed when your power transformer cooling system is an oil type. Transformer Oil is having extremely good insulating properties, good degeneration stability, low votality and resistance to grease formation. The mineral oil and paper insulation system has been extensively studied and used for more than 100 years. Transformer is an electric device, by the principle of electromagnetic induction, transfer electrical energy from one electric circuit to another, change of voltage and current. The oil’s “Dissipation Factor” is responsible for the oil’s dielectric properties and protects the transformer’s electrical system from possible short circuits. Mineral oil is the one which perfectly suits for heat transfer aspect of transformer at normal operating temperatures as it has high viscosity gradient whereas silicon oil has proved to be ineffective for the dissipation of heat. The oil insulation used in the power transformers act as electrical insulating medium as well as a coolant for the transformer. To resolve these problems and to develop a device capable of early detection of the internal faults in the transformer, the use of H 2 sensors that can be directly inserted to the transformer oil for continuous real-time monitoring of dissolved H 2 gas has been suggested. Oxidation stability is the factor by which the natural Ester oil grades down as it has the tendency of getting oxidized more easily. It possesses the advantage of high viscosity there by act as an effective coolant and reduces the heat developed by thermal stress. Transformer Oil does mainly two tasks. Lubricating Oils satisfy the needs of all core industrial sector of India. This is illegal and will get you into trouble when you are caught. The smooth operation of electrical equipment largely depends on the transformer’s internal condition. HyVolt products have very low pour points and excellent oxidation stability. Mineral oils consist of hydrocarbon components, that usually come from residual oil fractions of the appropriate viscosity level. If the voltage is below 11 kV, oil can be filled without vacuum, with the temperature of the dielectric liquid above 10ºC. This is because it tends to deteriorate over time. Transformer Oil does mainly two tasks. Considering these factors, oil units seem, by all accounts, to be the better alternative overall with higher energy efficiency, recyclability, low noise pollution, lower operational costs and a small environmental foot print. It is uninhibited electrical insulating oil made up of superior quality base oil for use as an insulating and heat transfer media in electrical Most modern transformers use oil for insulation and cooling. 2.
