In oil transformer which oil is used & what should be the insulation resistance & heating ..

Naphthenic mineral oil ( higher flash points ) and minimum
safe insulation resistance in 33KV TR-500 ohm
11KV TR-300 omh
insulation at temperaturs more than 120 to 140 c the gas
bubble are formed as a result of insulation deterioration
these is reasion of leading breake down.
