Name of 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).
WHAT will happen if you run oil transformer with out oil?
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.
What is a function of a Buchholz relay?
A Buchholz relay is designed to detect a failing oil-filled power transformer. It will automatically disconnect the transformer and produce an alarm signal.
What is the maximum allowable operating temperature of an oil-filled transformer?
For a transformer 50 degree c is stable. In most transformers if temp rises above 60 an alaram will sound ,if above 90 trip off. a temp controller which will measure the oil temp will do this actions.
Why are some transformers oil filled?
Transformer oil, or insulating oil, is usually a highly-refined mineral oil that is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled transformers, some types of high voltage capacitors, fluorescent lamp ballasts, and some types of high voltage switches and circuit breakers. Its functions are to insulate, suppress corona and arcing, and to serve as a coolant.After Transformer oil is used for a long-period, the oil will turn to dark liquid. The Transformer plays an important role in the generation, transmission and distribution of electrical energy. Under load the transformer, dissipates heat and the insulating oil acts as a coolant as well as an effective dielectric.Due to the highly hygroscopic nature of the transformer oil, it absorbs moisture from windings, which leads to gradual deterioration of dielectric strength. Also there are some waste impurities, gas contents in the transformer oil which destroy the oil's quality.Hi-tech Vacuum Transformer Oil Purification Systems is the most efficient and economical purification system.Hi-tech Vacuum Transformer Oil Purification Systems is applied to filter various of unqualified insulation oils including aging transformer oil specially for the power which is above 110KV, mutual inductor oil, switch oil and so on. Also it can inject the insulating oil into the transformers on-line.Hi-tech Vacuum Transformer Oil Purification Systems has the great abilities in removing impurities, particles, water content, gas content, acid, etc... making the waste transformer oil to be regenerated to new oil's quality for reuse.for more information, welcome to visit http://bestoilpurifier.bossgoo.com , or email us kevinnchiang@gmail.comAll the polution problems caused by waste oil will be solved by Hi-tech Vacuum Transformer Oil Purification Systems.
Oil filled transformer is usually used indoor or outdoor?
An oil filled transformer is usually used outdoors and a dry core transformer is usually used indoors.
Name of 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).
Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
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.
What is the purpose of the oil in a oil filled transformer?
cooling Not only that, but also to protect the windings from moisture.
What is the Cost of SF6 gas insulated Transformer?
2-3 times more than the cost of a mineral oil filled transformer.

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 is oil transformer?
Transformer oil is pure insulating oil.
Why is it the oil transformer commonly install outdoor?
Most outdoor power and distribution transformers are oil filled. There are two reasons for this: (1) to cool the transformer and, (2) insulate the windings and other components, allowing the overall physical size of the transformer to be reduced and, therefore, provide a smaller 'footprint'.
What is the present excise duty of transformer oil?
to cool a winding of transformer and it is a insulating material and transformer oil is a purifing oil
