Which type of oil is used in transformer for cooling the windings?
Mineral oil
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 type of oil is used for cooling arc welding machine coil?
which oil use for arc welding machine
What types of transformers used in 220 kv double bus switch yard?
We use double rating transformer, in this we have two type of cooling . ONAN & ONAF, According to cooling we have two rating.
Where the transformer oil is circulated in the transformer and how it27s cooling the transformer?
Heat is one of the leading causes of transformer failure. The main source of heat generation in transformers are caused by copper loss in the windings and core (I²R losses). If this heat is not properly dissipated, the temperature of the transformer will rise continually which may cause damage to the insulation. A transformer operating at just 10°C above its rating will reduce its life by 50% so it is imperative to understand how transformers are cooled and how to detect problems in their cooling systems. ANSI and IEEE require the cooling class of each transformer to appear on its nameplate. The cooling classification of a transformer, expressed in letters, designate the type cooling system used. Transformers may have multiple load ratings that correspond to multiple stages of cooling.
What is a wet-type transformer?
--transformer which is liquid cooled.. --normally used to couple telephone and electronic equipments. --care should be taken to maintain this type. -- fire proof vault is normally needed(b'coz it's using oil (mostly) for cooling).

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 type of transformer used in bed lamps?
If the bed lamps use a low voltage bulb then the type of transformer will be a step down transformer.
What type of transformer is used in a resistance furnace?
A resistance furnace runs on electricity so it will be some type of electrical transformer.
What type of transformer has only a single winding?
the auto transformer is the one winding transformer. it ismaily used in practical purpose.
Why you use oil in transformer not water?
Oil or similar is used as a cooling fluid in electrical transformer, because it is electrically insulating - which water is not. The figure of merit is the lack of conductivity.
