The oil is primarily there to carry heat away from the windings but also acts as an insulator.

How does conservator work in transformer?
To allow room for oil expansion and contraction. The transformer is completely filled with the oil and when it heats up under load or due to ambient temperatures, the oil has to have a place to go. In the event of colder weather or if the transformer is not under heavy load the oil cools and contracts creating a slight vacuum inside the tank. The conservator acts as a reservoir of oil that can then flow back into the tank so that no air enters it.
What is the function of oil temperature gauge in transformers?
Normally, in Transformers due to coil the temperature often rises up to a certain point.To minimise the temperature during transformer operation,specially engineered oil is used.To indicate the level of oil, a gauge is employed.
What is transformer ducts?
The transformer ducts are usually made up of strips of transformer board that is glued to the Diamond patter resin coated paper. It is widely used by transformers for manufacturing oil immersed distribution transformer windings.
What the transformer oil transformer provides?
Significantly-better cooling and insulation than air. This means that the transformer can operate at higher power ratings than an equivalent air-cooled transformer, and its internal electrical components can be much closer together, giving an oil transformer a much smaller footprint so it takes up far less space in a substation.
Why transformers are not excited with dc?
by using step-up transformer we can change the voltage in higher level
How you make-up the oil level in hermatic sealed power transformer 2000KVA?
The transformer will have to be taken out of service, and topped up. Usually, this would also be a good opportunity to test the oil for contaminants.
Why does an oil furnace require a step-up transformer?
An oil furnace has a step up transformer to generate a spark to ignite the oil spray at the tip of the nozzle.
How do you decide transformer oil filteration required?
When the water content in the oil in the Oil rises up to or more than 2% than it is needed to replace the transformer oil or filter it.

Where is a step up transformer used in the home?
An example would be if you had a oil furnace, the ignition system would be a step up transformer. The step up 120 volt to 15000 volt transformer is used to ignite the fuel that comes out of the nozzle under high pressure to make the fuel burn.
How many gallons of oil in a 2500 kva 12470 480 volt transformer?
Oil is used to cool the transformer. There is no telling what the transformer in question uses without knowing the specific part number and looking up the specification.
How do you Ignite Oil Furnaces?
With a special transformer that is stepped up to 10,000 volts

What is the Use of distribution transformer?
A transmission transformer steps the voltage up to a very high value so electricity can travel long distances on transmission lines from the power plant to a city or area with low loss. A distribution transformer steps the high voltage back down to a level that can be used for local distribution and use by businesses and homes.
