An Oil Dielectric Strength Tester is the standard for qualifying Transformer Oil. Thermal Stability would involve heating and then testing. I do not know of a product which controls heat and applies the HV test.

Transformer oil is pure insulating oil.
to cool a winding of transformer and it is a insulating material and transformer oil is a purifing oil
I am guessing at this one but probably to warm the oil so as to assure proper flow and prevent thermal shock once the transformer and its components are heated up under load.
Nytro libra is an uninhibited 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).
transformer consists of polychlorinated biphenyls,...etc
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.

minarel or power oil
Its "Mineral Oil".
it is a pit which is used to drain leakage oil of transformers .AnswerIt's a walled area, surrounding a transformer, intended to contain any oil leakage from a transformer.
