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.
17KV/min
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.
above thirty (30) KV (rms)
Heat engine utilizes low heat value of oil and also the fuel oil consumption for IC engine usually based on high heat value of oilby Shyam
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.
Because electorn ionised the moisture content and evaporated. Every trial for the same sample moisture content get reduced which helps to improve dielectric strength a bit. But if the sample having very low dielerctric strength it should be thrown.
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

You don't necessarily want the cheapest oil, diesels need GOOD oil. I am a diesel mechanic and I highly recommend Shell 15W40 motor oil.
Crankcase oil is engine oil , so yes
every 2 years
Yes, you need engine oil.
