Depends on the transformer. This can range from a few gallons to thousands of gallons.
Radiators are used in a transformer to cool the transformer oil through natural air or forced air flowing in these radiator fins. As the transformer oil temperature goes down due to cooling it goes to the transformer tank from bottom ,cool the windings and gets heated, and then returns to the radiator for next cooling .This cycle repeats as the oil flow is also natural due difference in temperature of oil on bottom and top. In big power transformers this oil circulation is forced by oil pumps for effective cooling. The radiator has many small fins and there are 4-10 radiator banks in a transformer depending on capacity and make of the transformer.
The basic difference between the air cooled transformer and oil immersed transormer is: If the heat generated in the transformer winding is capable of being swapped by the sarrounding ambient air without causing any problem to the performance of the transformer then its normally reffered as Naturally Air Cooled transformer or simply air cooled transformer. However when the capacity of the transformer increases, the heat generated in the winding of the transformer is more and the ambient air normally is inadequate to cool the windings and maintain the performance of the transformer. Its because of this reason the transformer windings are submerged in an oil tank. It has been observed that the hydrogen ions present in oil help to maintain the temprature of the winding of the transformer and thus overall performance of transformer.
An oil transformer is filled with PCB oil to better transfer heat from the windings to the outside case (and into the air).
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.
it is a pit which is used to drain leakage oil of transformers .AnswerIt's a walled area, surrounding a transformer, intended to contain any oil leakage from a transformer.
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
Transformer oil is pure insulating oil.
to cool a winding of transformer and it is a insulating material and transformer oil is a purifing oil

To cool and to insulate the transformer. Transformer oil has a higher specific heat capacity than air, so it is more efficient at removing energy through heat transfer, and limiting the windiings' temperature rise. Transformer oil has a much greater dielectric strength than air, which means that components at different potentials can be placed closer together, so the overall volume of the transformer can be made smaller, giving it a smaller 'footprint'.
