Thats way too big of a qurstion to expect anyone to answer in this forum. About like asking ho welectricity works. Try a more specific question.

Have some fun.
If this is not enough, type in Transformer training at Google.

Dry type has windings that are not submerged in oil. The others are (submerged in oil )

What's so hard about that?:smile:

Elmer Fud reference?

The new Elmer Fud.

a qurstion

Now I have a question?

Ok, ill try to narrow it down some. Thanks for letting me know that dry types dont have the oil, and the others do.

Whats the real advantage to having the oil type over the dry type??

Dry type transformers use air as their cooling medium. Dirty air means dirty transformers, dirty transformers mean more maintenance for internal cleaning. Air cooling requires large surfaces so dry type transformers are usually large compared to oil filled units.

Liquid filled/cooled (liquids can be oil, silicone, and gas) transformers use a liquid to transfer heat from the transformer core to radiator fins. Radiator fins are relatively easy to clean compared to dry type cores.

There is not a single advantage to one type other the other. Other considerations, such as liquid containment, short circuit capability, and overload capacity.

There are also incapsulated transformers in addition to oil filled, and dry type.

Dry type can be convection or forced air electric fans.

OIl filled can be mineral oil generally utilized outdoors due to flamibility issues. Then there are synthetic oils utilized indoors less risk from fire. The cooling fins on an oil filled can be convection or have cooling fans.
