You've read the user manual, haven't you?

You've rung the manufacturer, haven't you?

Now you're asking strangers. Why?

Please have a look at the trafo datasheet........you will find the values there

Further these questions are very vague........these values differ from one manufacturer to other.....so u better be specific so that you yourself dont get misleaded.

Lastly........try utlising your resources first.......good for you in the long run

Dear Smruti.sahu,

The di-electric strength of oil is expressed in terms of BDV. It tells the healthiness of the oil. If you are in India. Please refer IS 335 (for new Oil) and IS 1866 (for oil in service).

It depends on the working voltage and not the rating of the transformer.

Transformers don't have a BDV Value. Only the oil used in transformers have. Then also it is not related to the MVA Rating of the transformer, but the voltage rating.
