Transformer Oil

Which????? Mineral oil.

Why??? Because I said so.

Comments::::::::You should have read the manual or searched for "Transformer oil" on the web.

You forgot animal oil. How about lard or blubber?

They ain't no published research on the BDV of blubber, you dunce.

Tell me again why we should allow anonymous posters here?

Because self-abuse is one of the finest joys.

So we can do their homework for them.

You should use the fluid the transformer manufacturer specifies. Why? Because the warranty is voided if you don't.

Depending on the design of the transformer, the cooling media could be mineral oil, anhydrous nitrogen, air, paraffin, vegetable oil, sulfur hexafluorine, sodium or whatever. I've heard a rumor that some companies have considered using the blood of lazy, idiotic new employees that obviously did not earn their degree to cool their transformers.

Mineral because it works and is cheaper.

Other alternatives will depend on the particular transformer application, that is why there are so many different types of mineral and non-mineral based transformer oils on the market.

Mineral and vegetable both. Mineral is slowly being phased out because vegetable is less environmentally hazardous. Mineral does more damage to the environment than vegetable does. Also less hazardous to responders who must mitigate and then clean up the mess after a leak, explosion or fire.

Good Luck, Old Salt

Vegetable oil will go rancid.

Inhibitors are used to keep it fresh and not clogging up the fins or heat exchanger tubes.

Good Luck, Old Salt

Are you cooking or transforming?

those nutritional sites have a few pages from canola to coconut oil specs for high temp reactions and health to the body

hmph

just so it is not the goo out of old capacitors...

by th'way: a good "scientist" (knowledge-gatherer, of scientia:knowledge) simply does not have any -some-think-necessary- "good ideas" (subjectiveness as involved beyond a knowledge of...) but good scientists DO HAVE good objective data-acquisition skill/notation-sets, and leaves the theories to the 'knowledge-interpreting-benders' .

Definitely mineral oil. Any vegetable oil, when heated would, when heated, eats oxidised and leaves the solid layer of oxidised oil, that would hinder heat transfer.

Mineral oil is of much recent origin than vegetable oil. Vegetable oils have been in use as lubricants, creating light (Wick lamps) apart from culinary use since time immemorial. Using as an insulator in transformer is also of recent origin. transformer oils have to be tested periodically for free acidity. This free acidity is even more pronounced when vegetable oils are used, unless refined vegetable oils are used, which makes them even costlier. When free acidity increases, failure of transformers is even more frequent. However, vegetable oils could be used, as a transformer insulating oil, according to the information given by fellow members. In any case, vegetable oils per se are costlier and considering their shorter life they may not be cost effective.

The cost of only one Mineral Oil spill is far greater than all the costs of using a highly refined vegetable oil without the Haz Mat liabilities. Also a Veg Oil spill is far less than one of Mineral Oil.

Life time costs of Vegetable Oil are much lower than Mineral Oil.

Good Luck, Old Salt

and the spectacularly bright fires, too , after the big bang

(happened to be seen out of the corner of my eye working on a roof top chiller a block away from an exploding TX in the evening)

How is the TX being cooled? At all with fans or GeoThermal groundloop pre-cooling-hybrid?
