was 1P2p oil used in electric Transformers
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.
Oil used in electric transformers.
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.
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.
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.
One can shop for affordable oil filled electric heaters from many different stores and retailers. Some examples of these stores include Target, ZORO Tools, and Frontgate.
An oil filled electric space heater produces a more "even" heating without the hotspots that standard electric space heaters can produce. Also it is not possible for something poked into the oil filled electric space heater to touch the electrical heating element wires as is possible in standard electric space heaters (which would shock you).
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.
High power transformers used to contain PCP's, but modern transformers contain mineral oil because it is less environmentally sensitive.
what are the major advantages of dry type transformers over oil type transformers
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).
No. I spoke with customer care representatives of two brands (Delonghi and Holmes) of electric oil-filled heaters, and both said that the oil will not freeze. I asked whether there would be any harm in leaving one of their radiators in a car for several days at below-freezing temperatures, and was assured that this would not be a problem.
