There are two kinds of transformers, one which is used to produce high voltage known as step up transformer and which is used to decrease the voltage is known as step down transformer. Transformer oil is used in oil-filled and submersible transformers to maintain temperature of transformer. In addition to its namesake, it’s also used in high-voltage switches, some capacitors, and circuit breakers. Why is transformer oil purification essential? In other words it is a by-product of the petroleum distillation. After testing Various oil samples, it is noted that a mixture of mineral oil with 20% Ester oil tends to be more reliable than use of mineral oil alone and hence prove to be cost effective. Where as oil cooled transformer are ideal to be used in outdoor installations due to possibility of oil spillage and leaks which pose a fire risk. In case of heavy faults the oil temperature increases suddenly to high values. Transformer Oil Testing is a proven loss prevention technique which should be a part of any condition based predictive maintenance program. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. they are not flammable and have high electrical insulation but they are highly non-biodegradable, toxic, bioaccumulative, and cannot be safely disposed of. Transformer insulating oil is a dielectric liquid that is intended for cooling and insulating electric power transformers and other high voltage equipment. Find here Used Transformer Oil, Second Hand Transformer Oil manufacturers, suppliers & exporters in India. They can then sell the oil for about $12 per liter to chefs at cooking stands who use it to fry food. Transformer oil is an oil which remains stable at high temperature. 8.8 Protection Against Leakage of Insulating Liquid & SF6 Gas. This early warning system can allow maintenance management to identify maintenance priorities, plan work assignment schedules, arrange for outside service, and order necessary parts and materials. But adding 20% Ester oil does not affect the margin of viscosity index of the mineral oil. Firstly, it is liquid insulation in electrical power transformer.

The mineral oil has proved to be more susceptible to the ageing impurities and the Ester oil to some extent. The transformer oil is pumped in to the high vacuum oil filtration machine by means of the inlet pump provided. Most of the transformers use mineral oil as liquid insulation due to its extended dielectric properties and withstanding capabilities. Transformer Oil is responsible for protecting the transformer’s main core and the winding. Coolant fluid is a special fluid with additives because it need to remain liquid at low temperature but does not evaporate at high temperature. Technically speaking, transformer oil is a mineral oil used to cool and insulate the fins of an electric transformer. Application of transformer oil can also be seen in high-voltagecircuit breakers and switches. The process continues until oil appears in stopper orifices. Each oil has its own limitations and merits. Transformer is the soul of Morden power system. Coolant is a fluid. heights and some are small enough to hold in your hand. All these lead to failure of the equipment which in turn create economic loss. Modine (CIS) designs and manufactures transformer type BETA/CETA and ALFA oil coolers for oil insulated power transformers and reactors. Oxidation stability is the factor by which the natural Ester oil grades down as it has the tendency of getting oxidized more easily. The culprit is an unusual one: A vandal who is selling the toxic oil, drawn from the transformer, to chefs who use it for frying food in roadside stalls. Automotive Oil is greatly designed for heavy/medium/ light commercial vehicles, agricultural tractors, pump sets, outboard motors, marine engines, commercial & passenger cars, two and three wheeler etc. Transformer either increases or decreases AC voltage. The former uses transformer oil (and of course other oils such as beta oil) as the cooling and insulating medium, and the latter uses air or other gases such as SF6 as the cooling medium. Oil filled transformer is to place the body consisting of iron core and winding in a fuel tank filled with transformer oil. It possesses the advantage of high viscosity there by act as an effective coolant and reduces the heat developed by thermal stress. Transformer are used to meet a wide variety of requirements. Transformer Oil does mainly two tasks. There are two mode types of transfer. An Insulating Oil must have the following properties: 1) Excellent dielectric properties resulting in minimum power loss.
