The cooling behaviour of oil filled transformer is influenced by several factors including the type and volume of insulating oil, the surface and design of the radiators, the availability of oil pumps ...

Under such circumstances, low impedance faults that result in arcing can appear in transformer tanks once the oil loses its dielectric properties. Oil is then vaporized and the generated gas is ...

With aging transformers, the real risks to utilities and their customers are the potential ancillary costs in case of an eventful transformer failure. Many of these costs are related to the ...

Furthermore, the conditions in a transformer are generally such that it would be difficult to apply. However, it is shown in the paper that the cooling of oil-immersed transformer windings, for a ...

All petroleum products, that is to say, – Petrol, diesel, crude oil, lubricating oil, transformer oil, brake or clutch fluid, bitumen (asphalt), tar and others, but excluding LPG, kerosene and naphtha ...
