The oil in a transformer has two functions: Oil is a better electrical insulator than air is, so high voltage parts can be placed closer together, saving space and materials. Also, oil is more efficient at cooling the transformer. The oil circulates inside the transformer, removing heat from the internal core and transferring it to the cooling radiators or the surface. In small Transformers, this occurs naturally, by convective currents. In large transformers, there are thermostatically controlled pumps to assist this cooling cycle.

Why grease is used in electrical transformers?
Grease is not used in transformers. An insulation oil is used to circulate around the internal coils to dissipate the heat generated when the transformer is in operation. Thermo syphon principals are used. Warm oil moves to the top of the transformer case and is displaced by cooler oil moving to the bottom creating a flow in the oil and there by aiding in the cooling of the coils. Transformers in larger sizes have cooling fins or tubes through which the oil flows to give more surface area to dissipate the internal coil heat. Smaller size transformers use the oil contact with the oil containment shell of the transformer to dissipate the heat.
What are the advantages of dry type over oil type transformers?
what are the major advantages of dry type transformers over oil type transformers
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.
Is dry type transformer air conditioned?
To my knowledge no transformer is air conditioned. Some transformers have fans mounted on them, however, for uprating purposes. I don't believe this is an effective cooling mechanism for dry type transformers either (fans are usually used on oil filled transformers).
What is the oil used in a transformers?
Transformer oil is a highly refined mineral oil.
Which oil is used in x ray machine for insulation and cooling?

Standard transformer cooling methods?
Standard transformer cooling methods include; Air cooling and oil cooling.AnswerTransmission and distribution transformers are oil filled. Cooling is achieved either by natural convection yo the sides of the tank (small distribution transformers) or through cooling tubes, or by pumped circulation through external heat exchangers. The heat exchangers themselves, are cooled by natural convection, forced air draught, or water.
