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.

Different types of insulation used for transformers?
Most transformers are insulated with polymers or porcelain. Some transformers have an oil based insulation which must be kept dry to remain effective.
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.
What are the Relays in transformer?
There are many types of protection relays used in transformers depend upon its construction, size, use etc. They are 1. Buchholz relay for incipient faults like short ciruit, winding temparature protection, oil temparature protection, oil level protection, oil pressure protection, Pressure relief valve (for oil filled transformers) 2. Differential protection 3. Thermal Protection 4. Earth fault protection 5. Over current protection 6. Over excitation protection(where OLTC is used) etc
WHAT IS A BREATHER AND WHAT IS IT USED FOR IN TRANSFORMERS?
A breather is used for underwater breathing in the Transformers Franchise. Most transformers have this feature, however, there are some who don't, like Pptimus Orime, Negatrom and more.
What is transformer oil soak pit?
it is a pit which is used to drain leakage oil of transformers .AnswerIt's a walled area, surrounding a transformer, intended to contain any oil leakage from a transformer.
Was electric transformers filled with 1p2p oil?
was 1P2p oil used in electric 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.
How do oil cooled transformers without conservator work?
Oil filled transformers without a conservator are usually distribution transformers with relatively-low kV.A ratings. The volume of oil in these transformers is comparatively low and there is no need to allow for any substantial expansion, which is the main purpose of a conservator tank.
Definition working principles of oilfilled transformer?
Oil Filled Transformers Oil Filled Transformers are known for consistent performance even in harsh weather conditions like extreme temperature and atmospheric pollution. We follow oil impregnation procedure is used in the oil filling in these transformers. These are also known for low power loss, low noise and longer functional life. We have a vast array of Oil Filled Transformers for our clients that we manufacture as per the industry standards. In our range, clients can avail Amorphous Core Transformers, Converter Duty Transformers, Furnace Duty Transformers and Power Transformer. Besides, we also meet the demands of Distribution Transformers in Voltage ranges of 11 KV, 22 KV and 33 KV, Power Transformers upto 60 MVA in voltages of 11 KV, 22 KV, 33 KV, 66 KV & 132 KV and Isolation Transformers.
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).
How do you identify a liquid transformer?
Most transformers have a name tag, start there. If it's outside, theres a 75% chance it's filled with oil. Generally oil filled transformers are housed in a cylindrical powder coated steel container, green, grey or tan. Ranging in size of pole mount(Keg), pad mounted (Car), to Substation transformers(size of your house) Larger Oil filled transformers have cooling capability, large radiator looking thing on the side with one to many electric fans blowing air past the cooling fins.
Why is class A winding insulation is only used in oil filled transformers?
This is because the oil has flash over point at 140 deg.Cl and the winding insulation cannot exceed the flash point of the oil.
What are the advantages of dry type over oil type transformers?
what are the major advantages of dry type transformers over oil type transformers
Different types of insulation used for transformers?
Most transformers are insulated with polymers or porcelain. Some transformers have an oil based insulation which must be kept dry to remain effective.
What is the coefficient expansion of transformer oil?
Transformers can be filled with various types of Refined Mineral Oil. That coefficient is something you would find in specifications of the supplier. Commonly, it is .08% per degree Centigrade.
Which are best oil-filled or non-oil-filled radiators?
oil filled
What are the types of transformer?
There are a variety of types of transformers. These include autotransformers, polyphase transformers, leakage transformer, resonant transformers, as well as audio transformers.the decepticons are the bad guys, and the autobots are the good guys. bumblebee and optimis prime are autobots. megatron is a decepticon.
