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
What type of oil transformer is nytro Libra oil?
Nytro libra is an uninhibited transformer oil
What is means of transformer oil what contents is there in that oil?
transformer consists of polychlorinated biphenyls,...etc
What is the working of oil level indicator of transformer?
The oil level indicator in a transformer is used to show the oil level.
How do you stop oil leakage in Transformer?
If you have a large power transformer that is leaking oil, do NOT touch it! Older transformer oil contains PCB's which are extremely toxic!! Get a licensed firm to test the oil for PCB's and repair or replace the transformer. Don't fool around with this! PCB's are a serious danger to you and others. Do not let this go. Get it fixed right away!
What is the expriy date of 11 KV Transformer oil?
It is better to check the BDV (Break down voltage) of the oil to decide whether the said oil is usable for 11KV application, instead of depending upon its "expiry" date.
What are the conditions for operate the three phase transformer?
The BDV value of the transformer oil should be above 50kv winding resistance value should me minimum depends upon the KVA Of trans earthing should be provide for the trans air should be release inside of the tranformer insulation level should be check to operate the transformer these are all the initial condition to operate the trans
How much kv require for trasformer oil BDV?
above thirty (30) KV (rms)
What is oil transformer?
Transformer oil is pure insulating oil.
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
Bil of power transformer?
B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
What type of oil transformer is nytro Libra oil?
Nytro libra is an uninhibited transformer oil
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 is means of transformer oil what contents is there in that oil?
transformer consists of polychlorinated biphenyls,...etc
What is BDV test for distribution transformer?
When you say BDV you might mean the dielectric strength of transformer oil. A new transformer oil should have at lest a dielectric strength of 39 KV. from a British standard.Transformer oils used are normally tested using ASTM D877-82 with the KV strength tester using 1" electrodes spaced 0.1" apart and the test voltage increased at 3,000 volts/min until it breaks down. The average Kv obtained after 8 trials is considered the Oil dielectric strength.Using this test method,dielectric strength at 30 kv and above is considered good. Dielectric strength between 23 to 29Kvis considered usable, but requires filtering. Below 23 kv, the transformer oil should be replaced.Another method ASTM D18747-82 uses the small radius electrodes but spaced only .o4 inches. The test voltage is 500volts/min and increased until breakdown. The dielectric strength is still the average Kv obtained in 8 trials. The dielectric strength of 28-29Kv is considered good. Below 28 kv, the transformer oil is usable but requires filtering. The latter method is considered a better test method
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.
How the transformer oil is circulated and how it works in the transformer?
convection currents
