Not only that, but also to protect the windings from moisture.

Oil filled transformer is usually used indoor or outdoor?
An oil filled transformer is usually used outdoors and a dry core transformer is usually used indoors.
Name of transformer oil?
An oil transformer is filled with PCB oil to better transfer heat from the windings to the outside case (and into the air).
Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
What is life expectancy of oil filled transformer?
6 years
Is there need of transformer oil in all transformers?
No not really only some do :DAnswerFor transformers used in transmission and distribution systems, yes. Transformer oil is necessary for cooling and insulation purposes, enabling the 'footprint' of an oil-filled transformer to be smaller, and its rating to be higher, compared with those not filled with oil.
What is the Cost of SF6 gas insulated Transformer?
2-3 times more than the cost of a mineral oil filled transformer.
WHAT will happen if you run oil transformer with out oil?
As well as providing a cooling medium, transformer oil is also used to insulate a transformer. As its dielectric strength (how well it insulates) is much higher than air, it means that components within a transformer that are at different potentials can be placed much closer together if they are immersed in oil. So, operating an oil-filled transformer without oil will likely cause insulation breakdown within the transformer.
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 a function of a Buchholz relay?
A Buchholz relay is designed to detect a failing oil-filled power transformer. It will automatically disconnect the transformer and produce an alarm signal.
What purpose of oil filter in transformer?
To remove impurity particles which could reduce the insulation property of the oil as well as that of the windings.
What is difference between a wet type and dry type transformer?
Transformer oil is a much better electrical insulator than air. So, in large transformers, oil is used to reduce the flashover distances between live internal parts, thus reducing the overall bulk of the transformer. At the same time, oil helps cool the transformer either by natural convection, or by forced circulation.'Dry transformers' are transformer that do not use oil for insulation or cooling purposes. They tend to be transformers with lower voltage and power ratings, where flashover and cooling is far less relevant.
What is oil transformer?
Transformer oil is pure insulating oil.
