Blowdown Valves
In case of Transformer oil the meaning of BDV is break down voltage. It refers to the one of the tests of the oil.
to cool a winding of transformer and it is a insulating material and transformer oil is a purifing oil
Nytro libra is an uninhibited transformer oil
transformer consists of polychlorinated biphenyls,...etc
The oil level indicator in a transformer is used to show the oil level.
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!
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.
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
The BDV (Breakdown Voltage) value of engine oil measures its dielectric strength, indicating how well the oil can insulate and resist electrical breakdown. A higher BDV value signifies better quality and performance, as it can help prevent the formation of sludge and ensure effective lubrication under high temperatures and pressures. Typically, BDV values for engine oils should be above 30 kV to ensure proper functionality and longevity. Regular testing can help monitor the oil's condition and its ability to protect engine components.
Transformer oil is pure insulating oil.

B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
An oil transformer is filled with PCB oil to better transfer heat from the windings to the outside case (and into the air).

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.
