<VV> Moving parts in a transformer

[ScottyGrover at aol.com]

And what does all this comparison with the operating characteristics of a  
transformer have to do with what happens in an engine?  How this hBN  
affects oil in a Corvair can best be determined by mixing the hBN with motor oil  
and operating the car for a while, at the same time making measurements of  
pertinent operating characteristics; I think you could easily come up with  
desirable parameters for operation, John, and I would very much appreciate 
it if  you would.

Well, nearly all of them move the oil via convection, as pumps,  etc., add 
to the cost, complexity, and diminish reliability. 

Most tap  changers are done in a switch filled with SF6, as switching in 
oil under load  can have explosive consequences. 

At any rate, what goes on in a  transformer is nothing like what goes on in 
an engine. Engines run a LOT  hotter, have high pressure lubricated 
surfaces, the oil is exposed to  combustion products, etc, none of which goes on in 
a transformer.

Some of the  larger transformers do have pumps, and radiators.  They also 
have  
moveable parts such  as tap changers that will step up or step down  the 
voltage 
from an electronic system when the need for a change is  sensed.  If the 
oil gets 
to hot it can be shut down  automatically.
