why mentioning loss angle 0.002 in transformer
7.6 pounds/gallon
The oil should be greater than 100M Ohms resistance. If a flash over occurs within the transformer the oil has to be replaced
Density of Transformer Oil at 29.5oC is 0.89g/cm3.The exact density of transformer oil depends upon the manufacturer but, expressed in SI units, is typically a little less than 900 kg/m3 at 20oC. The J&P Transformer Book states that 'a limit of 895 kg/m3 at 20oC ensures that the temperature (of the oil) must fall to -20oC before the density of the oil would exceed that of ice' -thus ensuring that if ice forms, then it would remain at the bottom of the tank.

Transformer oil is pure insulating oil.
1KG of transformer oil will sum up to 0.815litres.
to cool a winding of transformer and it is a insulating material and transformer oil is a purifing oil
Nytro libra is an uninhibited 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).
transformer consists of polychlorinated biphenyls,...etc
convection currents
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.
